If theenginehasbeen running,allow it to cool for at leasthalhour beforecleaning. Cleanall exterior surfaces, touchupandamaged paint, and coatother areas thatmay rustwith a lighof oil.

Using a garden hose or pressure washing equipment can forwater into the air cleaner or muffler opening. Water in the air

cleaner will soak the air filter, and water that passes throughair filter or muffler can enter the cylinder, causing damage.

Gasolinewill oxidize and deterioratein storage. Deteriorated

gasoline will causehard starting, and it leaves gum depositsclogthe fuel system. If the gasoline in your engine deterioratduringstorage, youmay needto havethe carburetor, and othfuel systemcomponents,servicedor replaced.

Thelength of time thatgasoline can beleft in your fuel tankacarburetor withoutcausing functional problems will vary withsuch factors as gasoline blend, your storagetemperatures, awhether thefuel tankis partially or completely filled. The air ipartially filled fuel tankpromotes fuel deterioration.Very warstoragetemperaturesaccelerate fueldeterioration.Fuel probmay occur within a few months, or even less if thegasoline wnot fresh when youfilled the fuel tank.

Fuel system damageor engine performance problems resultfromneglectedstoragepreparation are notcoveredunder thDistributors Limited Warranty.

You can extend fuel storage lifebyadding a gasoline stabilizethat is formulated for thatpurpose, or youcan avoid fueldeterioration problems by draining the fuel tankand carburet

When adding a gasolinestabilizer, fill the fuel tankwith freshgasoline. If only partially filled,air in thetank will promote fuedeterioration duringstorage. If youkeepa container of gasolfor refueling, besure thatit contains only fresh gasoline.

If your enginewill bestored with gasoline in thefuel tankandcarburetor, it is important to reduce the hazard of gasoline vaignition.Selecta well-ventilatedstorageareaaway fromanyappliance thatoperates witha flame, such as a furnace, wateheater, or clothes dryer.Also avoidany areawith a spark-producing electric motor, or wherepower tools are operated

If possible, avoid storageareas withhigh humidity, becausetpromotes rust and corrosion.

Keepthe engine level in storage. Tilting can cause fuel or oilleakage.

With the engine and exhaustsystem cool, cover the engine tokeep out dust. A hot engineand exhaust systemcan ignite orsome materials.Do not use sheet plastic asa dustcover. Anonporous coverwill trapmoisturearound the engine,promrust and corrosion.

Gasolineis highly flammable and explosive, and youcan beburned or seriously injured when handlingfuel.

Stopengine and keep heat, sparks, and flameaway.

Wipeup spills immediately.

Place anapprovedgasoline container below the carburetor, anduse a funnel to avoidspilling fuel.

If the cylinderwas coated withoil duringstoragepreparationengine will smoke brieflyatstartup.This is normal.

Check your engine as described in the BEFORE OPERATIONCHECKSsection of this manual (see page ).

If equipped witha battery for electric starter types, rechargetbattery oncea month while the engine is in storage.Thiswill help to extend the service lifeof the battery.

Handle fuel onlyoutdoors.

Remove the carburetordrain boltand gasket. Remove thesedimentcup and O-ring, then move the fuel valve lever to theON position.

After all the fuel has drained into the container, reinstall thedrain bolt, gasket, sediment cup and O-ring. Tighten the drainboltand sedimentcup securely.

Change the engine oil (see page ).

Poura tablespoon 5 10cm (5 10 cc) of clean engine oil intothecylinder.

Pull thestarter rope several times to distribute theoil in thecylinder.

Reinstall the sparkplug.

Pull thestarter rope slowly until resistanceis feltand the notchon thestarterpulley aligns with theholeatthetop of the recoilstarter cover.This will close the valves so moisturecannotenterthe engine cylinder. Return the starter rope gently.

Remove the sparkplug (see page ). If theenginehasbeenrunning,allow it tocool forat least15

minutes beforeloading the engine-powered equipmenton thtransportvehicle.A hotengine and exhaustsystem can burnand can ignitesomematerials.

If the fuel was drained during storagepreparation, fill the tanfresh gasoline. If you keep a container of gasolinefor refuelinsure it contains only fresh gasoline.Gasolineoxidizesanddeteriorates over time, causing hardstarting.

Keep the engine level when transporting to reducethe possibof fuel leakage.Turn thefuel valveto theOFFposition (seepage ).

Emission Control System Information

Source of Emissions

Tampering and Altering

Problems That May Affect Emissions

Replacement Parts

Maintenance

The U.S., California Clean Air Acts and Environment Canad

Thecombustion process produces carbon monoxide,oxidesnitrogen, and hydrocarbons.Control of hydrocarbons and oxof nitrogen is very important because, under certainconditiothey react to formphotochemical smogwhen subjected tosunlight. Carbon monoxidedoesnot react in the sameway,bis toxic.

Hondautilizes lean carburetorsettings and other systems toreducethe emissions of carbonmonoxide,oxides of nitrogenhydrocarbons.

EPA, California and Canadian regulations requireallmanufacturers to furnishwritten instructions describing theoperation and maintenanceof emissioncontrol systems.

Thefollowing instructions and procedures mustbefollowedorder tokeep the emissions from your Honda engine withintemissionstandards.

Tampering withor altering the emissioncontrol system may

increase emissions beyond the legal limit. Amongthoseactsconstitute tampering are:

Removal or alterationof any partof the intake, fuel, or exhasystems.Alteringor defeating the governor linkage or speed-adjustimechanism to causethe engine to operateoutsideitsdesigparameters.

If you are aware of any of thefollowingsymptoms, haveyouengine inspected and repaired by your servicingdealer.

Hard starting or stalling after starting.

Rough idle.Misfiring or backfiring under load.Afterburning (backfiring).Blackexhaustsmoke or high fuel consumption.

Theemissioncontrol systems on your Hondaengine weredesigned, built,and certified to conformwithEPA, CaliforniaCanadian emissionregulations. We recommendthe useofgenuineHonda parts whenever you have maintenancedone.Theseoriginal-designreplacementparts are manufactured tosamestandards as the original parts, so you can beconfidenttheirperformance.Theuseof replacementparts thatare notoriginal designand quality may impair the effectiveness of yo

emissioncontrol system.

A manufacturer of anaftermarketpart assumesthe responsibthatthe partwill notadversely affectemissionperformance.Tmanufacturer or rebuilder of the partmust certify thatuseofpartwill not result in a failureof theengine to comply withemissionregulations.

Follow the maintenancescheduleon page . Remember thatschedule is based on theassumption that your machine will bused for itsdesignedpurpose.Sustainedhigh-loador high-temperatureoperation, or usein unusuallywetor dusty condwill requiremore frequent service.

When the carburetor has been modified for high altitude operation,

the air-fuel mixture will be too lean for low altitude use. Operationat altitudes below 1,500meters (5,000 feet) with a modified

carburetor may cause the engine to overheat and result in serious

engine damage. For use at low altitudes, have your servicingdealer return the carburetor to original factory specifications.

Even withcarburetormodification,engine horsepower willdecrease about 3.5%for each 300-meter (1,000-foot) increaseinaltitude. Theeffect of altitudeon horsepowerwill begreater thanthis if no carburetor modification is made.

High altitudeperformance can be improvedbyspecificmodifications to the carburetor. If youalways operateyour engineataltitudes above 1,500 meters (5,000feet), have your servicingdealer perform this carburetormodification.Thisengine,whenoperatedathigh altitudewith the carburetormodifications forhigh altitudeuse, will meeteachemissionstandard throughoutitsuseful life.
