FOR YOUR SAFETY - PLEASE READ THESE WARNINGS!

ENGINE WARNINGS

● Never use any other fuel in your engine other than glowfuels specifically designed for use in model car engines. Use ofany other types of fuel can cause severe damage to the engineand/or personal injury. NEVER use gasoline!

● Never operate your model on any public streets. This couldcause traffic accidents, personal injury or property damage.

● Glow fuel engines emit exhaust vapors that are poisonousand can be dangerous to your health. It is important that youoperate your engine in a very well ventilated area, preferablyoutdoors.

● Before starting the engine, make sure that the throttle trim isset to the idle position. Starting the engine at any setting aboveidle can cause the truck to lurch out of your hands.

● When the engine is running, there are certain parts that ro-tate at high speeds. Be careful not to touch the drive shafts,gears, clutch assembly or any other moving parts. Serious in-jury could result.

● It is normal for the engine and tuned pipe to get very hotduring operation, especially the cylinder head and muffler ortuned pipe. Never touch the engine or muffler assembly whilethey are hot.

● Model car engines produce vibration when they are run-ning. It is important to periodically check the engine mountingscrews, muffler screws and other assemblies to ensure they aretight. Running the engine with the engine mounting screws loosecan lead to severe engine and/or chassis damage.

FUEL WARNINGS

● Nitro fuels like those used in your XTM Racing nitro truckare poisonous. Follow all the precautions that are printed on thefuel manufacturer's container.

● Keep fuel out of the reach of children.

● Nitro fuel is extremely flammable. Keep away from highheat, sparks and flame.

GENERAL TRUCK WARNINGS

● Under no circumstances should you operate your model incrowds of people. Serious injury could result.

● Never operate your model on busy streets or if there are carsaround. Never drive your model at night, either.

● Do not use your model to chase pets or other animals.

● The radio system included in your model is not waterproof.Therefore, do not drive through water, wet grass or mud.

● Because your model is operated by radio control, it is im-portant to make sure you always are using fresh and/or fullycharged batteries. Never allow your batteries to run low or youcould lose control of the model.

● If your model becomes stuck, allow the engine to idle, thenretrieve your model by hand.

● To prevent excessive r.p.m.'s from damaging the engineand/or drive-train components we suggest reducing throttle whilein the air during jumps.

Our Recommendations

This section lists the recommended items necessary to run and maintain your new Baja Outlaw nitro truck. We have tested these itemsextensively with the Baja Outlaw and found that they offer the best in reliability and value.

FUEL

Fuel can make a big difference in the way your engine performs. For the break-in period you should use a fuel specifically designed forR/C car engines that contains no more than 20% nitromethane. Once the engine has been adequately broken in (about 30 minutes ofrun-time) you can switch to an R/C car fuel containing up to, but no more than, 30% nitromethane.

☛ We do not recommend using fuels designed for R/C airplane engine use. These fuels do not contain the proper amount oflubricants; therefore, they will cause the engine to overheat and severe damage to the engine will result.

Use the following fuels for the best performance:

Trinity 16% Nitro Car Fuel - Part # 837826 (use this for break-in)

Trinity 30% Nitro Car Fuel - Part # 837832 (use this after break-in)

GLOW PLUG WRENCH

A long reach glow plug wrench is necessary to easily and quicklyremove and replace glow plugs. The Magnum Long Reach GlowPlug Wrench is a good choice.

YOU SHOULD ALSO PURCHASE SOME SP ARE GLOW PLUGS

Even though your Baja Outlaw comes with a glow plug already installed in the engine, glow plugs wear out, especially during thebreak-in period; therefore, it's a good idea to have a couple of spares handy. The glow plug can make a big difference in how yourengine performs. We recommend using a "hot" type glow plug intended specifically for performance engines like the ThunderboltStandard Long # 115568 or the McCoy MC-59 # 690215. Do not use "cold" glow plugs or those intended for four cycle airplaneengines. Using the wrong type of glow plug will cause the engine to run erratically and make it difficult to tune properly.

GLOW STARTER

A glow starter is a battery operated device that when attached to theglow plug, heats the glow plug so that the engine can start. Theglow starter is then removed after the engine is running. The Mag-num Long Reach Glow Started is a perfect choice.

FUEL BOTTLE

Because fuel is packaged in quarts or gallons, you will need to use asmaller bottle with an extension tube or wand to fill the fuel tank.Fueling using this method is much easier and a lot less messy. TheMagnum 1/2A Fueling Bottle is a good choice.

Fuel Bottle Part # 237360

Glow Plug Wrench Part # 237425

Glow Starter Part # 237428


Other Recommended Items

● Trinity "8 Pack" AA Alkaline batteries for the transmitter -- Part # 837801

● Trinity "4 Pack" AA Alkaline batteries for the receiver -- Part # 837800

● Pacer After-Run Oil to "wet" the air filter and to lubricate the engine -- Part # 339127

● Emerald Nitro Car Cleaner to clean the chassis and engine -- Part # 340196

● Small flat blade screwdriver to make engine adjustments

● Adjustable wrench to make chassis adjustments

● Each radio system comes with crystals and stickers on the back of the transmitter and on the receiver showing which frequency theradio operates on (either in the 27Mhz or 75Mhz band). No two radio systems can operate nearby each other if they are on the samefrequency. You can purchase transmitter and receiver crystals separately and change them if you plan on running your truck with otherpeople. Listed below are the frequencies available for your radio system.

Battery Cover: This cover houses the 8 AA Alkaline batteries that power the transmitter.

Crystal: This is the frequency crystal of the transmitter. You can change crystals in both the transmitter and the receiver (in the truck)so that you and your friends can drive at the same time. No two radio systems nearby can be on the same frequency.

On/Off Switch: Turns the transmitter on and off. Two L.E.D.'s show the power of the batteries.

Servo Reversing Switches: Allows you to quickly and easily switch the direction the servos rotate by just flipping the switches on thetop of the transmitter.

Steering Wheel: Controls the trucks steering. Turn the wheel to the right and the truck turns right. Turn the wheel to the left and thetruck turns left.

Throttle/Brake Trigger: Controls the speed and braking ability of your truck. Pull the trigger to accelerate, release the trigger todecelerate and push the trigger to brake.

Trim Levers: These levers, one for steering and one for throttle/brake control, allow you to fine tune the servo's center by sliding thelevers on the transmitter.

Antenna: The antenna is part of the receiver. It receives the signals broadcast by the transmitter.

Battery Holder: The batter holder holds the 4 AA Alkaline batteries that power the receiver.

Body Post: The body is held to the chassis using four body posts. The body posts are adjustable so you can adjust the height of thebody on the chassis.

Bumper: The bumper is molded from high-impact plastic to provide excellent dampening in case of a front-end crash.

Engine: The engine is a nitro fuel powered device that uses a glow plug to ignite the fuel/air mixture. Modern R/C car engines are verysimple compared to "full-size" engines.

Fuel Tank: The fuel tank holds the fuel that your engine uses. This fuel tank includes a pump to prime the engine and a fuel pressurenipple that connects to the tuned pipe to pressurize the fuel system.

Shock: The shocks used on the Baja Outlaw are oil-filled and use a spring that is well suited for most off-road conditions. The shockscan be easily tuned for different driving conditions.

Steering Servo: This servo controls the truck's steering. A "servo saver" is installed to help prevent the servo gears from beingstripped out.

Tie-Rod: The tie-rod connects between the steering linkage and the castor block. The tie-rods are adjustable to you can make toe angleadjustments.

Tuned Pipe: The tuned pipe is an expansion muffler that greatly increases the power output of the engine.

Throttle/Brake Servo: This servo controls both the engine's throttle and the truck's brake.

Wheel/Tire Assembly: The Baja Outlaw includes molded rubber tires with a tread pattern that is good for most off-road applications.The wheels are spoke-style and molded from high-impact plastic for strength.


Preparing to Run Your Baja Outlaw Nitro Truck

Now that you are familiar with the major component parts of your truck, and with the functions of the Hitec Lynx Sport transmitter, it'stime to prepare your model for it's first run.

❑ Follow steps # 1 through # 16 in the Quick-Start Guide to prepare your model for its first run.

Range Checking the Radio System

To prevent any chance of a runaway model, the radio system should be range checked before the first run of the day and/or after a crash.To range check the radio system, do the following:

❑ Turn the transmitter on first, followed by the receiver.

❑ Extend the transmitter antenna completely.

❑ With the truck on the ground (without the engine running) walk away from the truck about 150 feet. Move the steering wheel whilelooking at the truck's wheels. The wheels should pivot smoothly back and forth as you rotate the steering wheel back and forth.

☛ If the radio system does not operate properly, please refer to the troubleshooting guide on page # 12 before going further.

WARNING

Never attempt to operate your model if the radio control system is not functioning properly. Doing so could be harmful to others aroundyou and/or to your model.

Double Check the Steering and Throttle/Brake Controls

❑ With the transmitter and the truck turned on, rotate thetransmitter's wheel forward (to the right). The front wheels on thetruck should turn right.

☛ If they don't, flip the steering servo reversing switch on thetop of the transmitter to change the direction.

❑ Rotate the transmitter's wheel backward (to the left). The frontwheels on the truck should turn left. Let go of the wheel. Thetruck's wheels should return to center.

☛ If the wheels do not point straight ahead (center) after youreturn the steering wheel to center, move the steering trim lever onthe transmitter to adjust the wheels so that they point straight ahead.



❑ Pull back on the throttle trigger. The carburetor rotor shouldopen completely.

❑ Let go of the trigger and the carburetor rotor should go back toits idle position - open about 1/16".

☛ If the carburetor rotor does not open when you pull back onthe trigger, flip the throttle servo reversing switch on the top of thetransmitter to change the direction.

☛ If the carburetor rotor does not open completely, move thethrottle trim lever on the transmitter until the rotor is opened com-pletely when you pull back completely on the trigger.

❑ Push the throttle trigger forward. The carburetor rotor shouldstay in the idle position and the brake lever should move forward toengage the brake.

❑ Let go of the trigger and the brake lever should disengage.

☛ You can adjust the brake linkage by sliding the wheel collar(on the brake linkage wire) forward or back. See page # 11 formore details.

Installing the Body

❑ Using a pair of scissors cut out each decal along its outer edges.

❑ Carefully adhere the decals to body using the photos on the box cover to position the decals.

❑ Double check that no parts of thebody touch the tires or the exhaust pipe. Ifany parts are touching, remove the bodyand use a pair of scissors to trim the bodyto clear any obstructions.

❑ The body height can be adjusted by re-moving the screws holding the body postsin place, readjusting the height of the posts,then reinstalling and tightening the screws.

☛ Make sure to leave enough clearancefor shock travel.

❑ Place the body onto the chassis, mak-ing sure the four predrilled holes in the bodyslide over the four body posts.

❑ Place one plastic washer over eachbody post and secure the body in place us-ing four metal body clips.


Becoming Familiar with Your Engine

Please refer to the photo below to familiarize yourself with your engine's carburetor. You should have a small flat blade screwdriverhandy to make adjustments to the carburetor.

☛ For even more information about the XTM engine in your Baja Outlaw nitro truck, refer to the separate XTM Engine Instructionsincluded with your truck kit.

Idle Stop Screw:

The idle stop screw is preset from the factory and should notrequire adjustment. The idle stop screw adjusts the closure ofthe throttle barrel. We recommend that the idle stop screw beadjusted so that the carburetor barrel stays open about 1/16".Turning the screw clockwise will cause the barrel to stay openmore. Turning the screw counterclockwise will allow the barrelto close more.

High Speed Needle Valve

The high speed needle valve is preset from the factory for the initial starting procedure. Do not make adjustments to it at this time. Thehigh speed needle valve is used to meter the air/fuel mixture at full throttle. Turn the needle clockwise to lean the mixture or turn theneedle counter-clockwise to richen the mixture. When you start the engine for the very first time, the needle valve should be turned incompletely, then backed out 2-1/2 turns. When you start the engine after that, leave the needle valve in the same position it was in whenyou shut down the engine.

Low Speed Needle Valve

The low speed needle valve is preset from the factory for the initial starting procedure. Do not make adjustments to it at this time. Thelow speed needle valve meters the air/fuel mixture at idle and during transition from idle to full throttle. Turn the low speed needleclockwise to lean the mixture. Turn it counterclockwise to richen the mixture. The low speed needle valve is preset from the factory,but minor adjustments may need to be made to suit your application: fuel used, glow plug and environment all contribute to the setting.To reset the low speed needle valve to the factory setting, follow these simple steps:

❑ Open the carburetor barrel completely.

❑ While holding the barrel open with your finger, use a small flat blade screwdriver to turn the idle mixture needle clockwise until itstops. From this point, turn the needle counterclockwise 5-1/2 turns. This is the factory setting.

Fuel Recommendation

Fuel can make a big difference in the way your engine performs. For the break-in period you should use a fuel specifically designed forR/C car engines that contains no more than 20% nitromethane. Once the engine has been adequately broken in (about 30 minutes ofrun-time) you can switch to an R/C car fuel containing up to, but no more than, 30% nitromethane.

☛ We do not recommend using fuels designed for R/C airplane engine use. These fuels do not contain the proper amount oflubricants; therefore, they will cause the engine to overheat and severe damage to the engine will result.

Glow Plug Recommendation

The glow plug can make a big difference in how your engine performs. We recommend using a "hot" type glow plug intendedspecifically for performance engines like the Thunderbolt Standard Long # 115568 or the McCoy MC-59 # 690215. Do not use "cold"glow plugs or those intended for four cycle airplane engines. Using the wrong type of glow plug will cause the engine to run erraticallyand make it difficult to tune properly.

Air Filter

The air filter is a very important part of your engine. Failure to use the air filter will damage the engine in a very short period of time.The foam air filter element needs to be oiled with after-run oil to work properly. See steps # 15 and # 16 in the Quick-Start Guide forfurther information.

Breaking In the Engine


Engine Break-In

☛ XTM .15 series engines are ABC engines. The cylindersleeve is tapered at the top, causing severe resistance when thepiston moves through the top of the stroke. This is normal. Whenthe engine heats up to operating temperature, this resistance willdecrease and the proper clearance will be achieved. The break-in procedure will guide you through the steps necessary to prop-erly break in your new XTM .15 series engine. Please followthe steps closely.

☛ The break-in process allows the engine parts to perfectlyfit to each other and properly protect each part from prematurewear. The engine should be broken in using a good quality R/Ccar fuel that contains no more than 20% nitromethane.

❑ Follow steps # 17 through # 22 in the Quick-Start Guide tofill the fuel tank and to become familiar with the engine's start-ing and shut down procedures.

❑ Once the engine starts, keep the glow starter attached tothe glow plug and let the engine to run for about 1 minute with-out giving it throttle. This will allow the engine to warm up. Atthis point the engine should be running very “rich” and thereshould be excessive white smoke coming from the exhaust pipe.

❑ After the engine has been running for about 1 minute, re-move the glow starter from the glow plug. Advance the throttlein short, quick bursts and drive the truck around for about 2-3minutes. If the engine is running rich enough, you should noticeexcessive white smoke coming from the exhaust and the engineshould sound like it’s running very rough. Also, the truck willbarely be moving. If there is not excessive white smoke comingfrom the exhaust, richen the high speed needle valve. After 2-3minutes stop the engine by pinching the fuel line to the carbu-retor (see Quick-Start Guide, step # 22).

❑ Let the engine cool for approximately 10 minutes, then re-start it. Set the high speed needle valve mixture to a slightly leanersetting, about 1/8 turn more in. Repeat the step above then stopthe engine and let it cool for approximately 10 minutes.

❑ Repeat the procedure in the step above, while leaning theneedle valve slightly more each time. In all, you should run theengine a total of about 30 minutes. After 30 minutes of run-timethe engine will be broken in. Run the engine with the needlevalve set slightly rich, but lean enough to power the truck. Atthis point the engine should hold a good setting on the highspeed needle valve and you can begin to fine tune the needlevalve settings to increase performance.

WARNING - Please Read Before Starting your Engine

If at any time the pull-start becomes very tight or difficult to pull - STOP! The engine has become flooded and the excess fuel must beremoved or damage to the pull-start and/or engine could occur. To remove the excess fuel from the engine follow the steps listed below:

❑ Completely close the high speed needle valve (turn clockwise) until it bottoms out.

❑ Remove the glow plug from the cylinder head.

❑ With the top of the engine pointing away from you, pull the pull-start cord several times to clear the excess fuel from the engine.

❑ Check to make sure the glow plug has not been fouled, then reinstall it.

❑ Reset the high speed needle valve 2-1/2 turns out from bottom.

☛ It is of the utmost importance that the engine never be leanedout too much. When running the engine, you should always beable to see a trail of white smoke coming from the exhaust pipe.If you can’t, stop the engine immediately and richen the mix-ture. You should also make sure there is plenty of air flowingover the cylinder head to keep the engine from overheating.

Fine Tuning Y our XTM Engine

After your engine has been broken-in, you can set the high andlow speed needle valves for optimum engine performance.

☛ Be careful to never lean the engine out too much. Re-member that the lubricants for your engine are suspended inthe fuel. If you lean out the fuel mixture too much you willalso be lowering the amount of lubricant entering your engine.Less lubricant means more chance of your engine overheatingand possible engine failure.

Setting the High Speed Needle Valve

❑ Start the engine and remove the glow starter from the glowplug. Allow the engine to warm up for about 1 minute.

❑ After the engine has warmed up, drive the car as you nor-mally would. If the engine seems to be running rich, lean themixture screw about 1/16 of a turn at a time until the desiredsetting is achieved. Always make sure you run the engine slightlyrich - you want to be able to see a white exhaust trail at all times.

❑ To get more power from your engine you can use fuelscontaining up to 30% nitromethane. We must caution you,though, that once you run the engine with increased nitro youmay not get satisfactory results if you decide to go back to alower nitro content. Also, if you use fuels containing 30% nitro,we highly suggest replacing the stock .01mm head gasket with athicker .02mm head gasket (available separately: P/N 148186)to lower the compression ratio. If you don’t lower the compres-sion ratio, overheating and erratic running will likely occur.

Setting the Low Speed Needle Valve

❑ Start the engine and lean out the high speed needle valveas per the previous steps. Close the throttle until the engine slowsdown enough so that the clutch is disengaged and the wheelsdon’t turn when the car is lifted from the ground. Allow theengine to idle for about 10-15 seconds.



❑ While holding the car off the ground (making sure to keep your fingers out of the moving parts) quickly open the throttle in a shortburst. If the engine just stops running as soon as the throttle is advanced, the idle mixture is too lean. With the engine stopped, richenthe idle mixture about 1/16 of a turn.

❑ Restart the engine and repeat the step above until the engine will transition smoothly and quickly. Very slight hesitation in thetransition is normal.

❑ If you quickly advance the throttle and the engine seems to be very rich during transition (i.e., lots of smoke coming from theexhaust and very rough sounding), the idle mixture is too rich. With the engine stopped, lean the idle mixture about 1/16 of a turn.

❑ Restart the engine and repeat the step above until the engine will transition smoothly and quickly. Very slight hesitation in thetransition is normal.

❑ Now drive the car as you normally would for a while to get a feel for how the engine reacts to throttle. Now that you know theproper way to tune the engine, you can make slight adjustments to the carburetor until you are satisfied with the performance.

Baja Outlaw Chassis Adjustments

Chassis alignment and geometry are important if you want your truck to perform good. A good performing truck means a truck that iseasier to drive, too. Follow our guidelines in this section to get the most out of your truck.

☛ It's very important that when making changes to the settings of your truck that you make the settings the same for each side.For example, if you change the camber angle on the right front tire, you must change the camber angle of the left front tire the sameamount. If you change the spring tension on the left front shock, you must change the spring tension on the right front shock thesame amount, and so on.

☛ Do not make any changes that are more than 3 degrees from the initial settings listed or the handling characteristics of your truckwill become very poor.

Camber

Camber changes the amount of the tire's surface that contacts the ground. Tires that are exactly perpendicular to ground have 0 degreesof camber. If the tops of the tires lean toward each other, the tires have negative camber. If the tops of the tires lean out away from eachother, the tires have positive camber.

Recommended Initial Settings:

For driving on smooth surfaces set both the front and back wheels at 0 degrees.

For driving on rough surfaces set the front wheels at -1 degrees and the back wheels at -2 degrees.

☛ Camber settings should be measured with the truck at its normal ride height.

☛ For more precise camber adjustments, use the R.P.M. Precision Camber Gauge (P/N 708099).

Castor

Castor is the angle of the front wheel spindles. With a lower degree of castor angle the steering will become much more sensitive thanwith a higher degree of caster angle. The Baja Outlaw comes stock with 20 degree castor blocks. You can purchase after-market 5degree castor blocks if you plan on running your truck mostly on-road.


Negative Camber Positve Camber

☛ Adjust the camber by turning the upperturnbuckles using an adjustable wrench.

(Camber angles exaggerated for photo clarity)


Toe Angle

The toe angle is the angle of both front tires to each other - when viewed from above. Toe-in (both tires pointing toward each other) willmake your truck more stable and it will track straighter. Toe-out (both tires pointing away from each other) will make your truck turnquicker, but it will be less stable.


0 degrees toe-in for overall best 4WD driveability.

☛ Adding more than 3 degrees or more of toe-in will result in excessive loss of speed anddifficulty steering the truck. Adjust the toe-in by turning the tie-rods with an adjustablewrench.

☛ For more precise toe-in adjustments, use the R.P.M. Toe-in Gauge (P/N 708049).

Spring T ension

By adjusting the spring tension of the shocks, you can increase steering sensitivity and increase the ride-height of the truck. How youdrive your truck will dictate what settings you should be using. As an example, if you're using your truck off-road and going over lotsof jumps, you may want to increase the spring tension of the front shocks to help prevent the front of the truck from bottoming out.

● Increase the spring tension by turning down the threaded spring tensioners at the topof each shock.


Turn the spring tensioners so that they are at the uppermost portion of the shock.

☛ When adjusting the spring tension, make sure to adjust the right and left sides equally.

☛For precision shock adjustments, use the Trinity Off-Road Shock Dyno (P/N 840021).

Shock Oil

Changing the shock oil (the oil inside the shocks) will change the dampening characteristics of the shocks. Typically, if you are runningon smooth surfaces, use a heavier weight oil. If you are running on rough surfaces, use a lighter weight oil.

☛ We recommend using only 100% Silicon Shock Oil. Do not use motor oil. The shock oil in the Baja Outlaw's shocks is good formost off-road applications.

Adjusting the Brake Linkage

The throttle/brake linkage in your Baja Outlaw nitro truck is preset from the factory; however, after running your truck you may findthat the brake linkage needs adjusting.

❑ With the transmitter and the receiver turned on, and the throttle/brake trim lever cen-tered, the truck should roll smoothly (i.e. the brake should be disengaged). If the brake isdragging when the throttle trigger is at neutral, the brake disc will wear out very quickly.To ensure that the brake is disengaged, always make sure that there is a 1/8" gap betweenthe linkage spacer and the brake lever.

☛ Your Baja Outlaw nitro truck includes a safety spring connected from the throttleservo arm to the rear bulkhead. Do not remove this spring. If you lose radio controlcontact with the truck, the spring will mechanically pull the throttle back to idle, prevent-ing a runaway truck and potential accident.


Maintenance

Following a simple maintenance schedule will ensure that your truck, engine and radio system operate in top condition every time youuse them. It is strongly suggested.

● Check the foam air filter element for dirt blockage. If thefoam is dirty, remove it from the rubber filter housing and wash itin liquid soap and warm water. Dry the foam element with apaper towel, reinstall it and "wet" it with after-run oil.

● Check the chassis for any loose screws, especially the engineand exhaust mounting screws. Tighten them if necessary.

● Check the steering linkage and the throttle/brake linkage forany signs of wear or misalignment. Tighten and/or readjust themif necessary.

● Once in a while, remove the wheels and clean the wheel bear-ings using a bearing cleaner. This will remove any dust and gritthat may over time, damage the bearings.

● Check the fuel system, including the fuel tank and fuel lines,for any signs of cracking or looseness. Replace any fuel line yoususpect may be damaged.

● After a period of time the chassis will accumulate a lot of dirtand debris, especially around the engine area. This build-up shouldbe cleaned off using a high-powered spray cleaner like EmeraldNitro Car Cleaner. Some nitro car cleaners will damage anodizedand/or plated parts. Test on an inconspicuous area first.

● After cleaning the chassis and engine with Nitro Car Cleaneryou should oil the moving parts of the chassis. Do not oil the clutchbell or spur gear (large exposed plastic gear) or the brake disc.

● Periodically check the condition of the transmitter and re-ceiver batteries. If you think they might be low, replace themwith a fresh set.

● Always use new fuel and keep the cap on the fuel tightlyclosed. As fuel ages it absorbs water, which degrades the fuelsperformance and will cause erratic engine operation.

● After you have finished using the engine for the day, removethe glow plug and squirt several drops of a high quality after-runoil into the cylinder. Reinstall the glow plug and crank the engineover a couple of times (without the glow starter attached) to dis-tribute the oil. This will prevent corrosion inside the engine.

● Never leave unused fuel in the fuel tank for more than a coupleof days. The Nitromethane and methanol in the fuel will evapo-rate, leaving the oil behind. This will eventually turn into a thicksludge that will require replacement of the fuel tank to fix.
