Measure the spark plugelectrode gap with a wire-type feeler gauge. Correct thegap, if necessary, by carefullybending the side electrode.

Visually inspect the sparkplug. Replace it if damaged orbadly fouled, if the sealingwasher is in poor condition,or if the electrode is worn.

Remove the spark plug with a13/16-inch spark plug wrench.

Disconnect the spark plug cap,and remove any dirt fromaround the spark plug area.

For good performance, the spark plug must be properly gappedand free of deposits.

If the engine has been running, let it cool before servicing thespark plug.

Proper storage preparation is essential for keeping your enginetrouble-free and looking good. The following steps will help tokeep rust and corrosion from impairing your engines function andappearance, and will make the engine easier to start when you useit again.

If the engine has been running, allow it to cool for at least half anhour before cleaning. Clean all exterior surfaces, touch up anydamaged paint, and coat other areas that may rust with a light filmof oil.

Using a garden hose or pressure washing equipment can forcewater into the air cleaner or muffler opening. Water in the aircleaner will soak the air filter, and water that passes through theair filter or muffler can enter the cylinder, causing damage.

Standard idle speed:

Turn the throttle stop screw toobtain the standard idle speed.

Move the throttle lever to itsminimum position.

Start the engine outdoors, andallow it to warm up to operatingtemperature.

Depending on the region where you operate your equipment, fuelformulations may deteriorate and oxidize rapidly. Fueldeterioration and oxidation can occur in as little as 30 days andmay cause damage to the carburetor and/or fuel system. Pleasecheck with your servicing dealer for local storagerecommendations.

The spark arrester may be standard or an optional part, dependingon the engine type. In some areas, it is illegal to operate an enginewithout a spark arrester. Check local laws and regulations. A sparkarrester is available from authorized Honda servicing dealers.

In Europe and other countries where the machinery directive2006/42/EC is enforced, this cleaning should be done by yourservicing dealer.

The spark arrester must be serviced every 100 hours to keep itfunctioning as designed.If the engine has been running, the muffler will be hot. Allow it tocool before servicing the spark arrester.

Remove the two 8 mm nuts and remove the muffler from thecylinder.

Remove the three 4 mm screws from the exhaust deflector, andremove the deflector.

Remove the 4 mm screw from the spark arrester, and removethe spark arrester from the muffler.

Install the spark arrester, muffler protector, exhaust deflectorand muffler in the reverse order of disassembly.

Use a brush to remove carbondeposits from the spark arresterscreen. Be careful not to damagethe screen. Replace the sparkarrester if it has breaks or holes.

Remove the 6 mm screw and four 5 mm screws from the mufflerprotector and remove the muffler protector.

Gasoline will oxidize and deteriorate in storage. Deterioratedgasoline will cause hard starting, and it leaves gum deposits thatclog the fuel system. If the gasoline in your engine deterioratesduring storage, you may need to have the carburetor and otherfuel system components serviced or replaced.

The length of time that gasoline can be left in your fuel tank andcarburetor without causing functional problems will vary withsuch factors as gasoline blend, your storage temperatures, andwhether the fuel tank is partially or completely filled. The air in apartially filled fuel tank promotes fuel deterioration. Very warmstorage temperatures accelerate fuel deterioration. Fueldeterioration problems may occur within a few months, or evenless if the gasoline was not fresh when you filled the fuel tank.

Fuel system damage or engine performance problems resultingfrom neglected storage preparation are not covered under theDistributors Limited Warranty.

You can extend fuel storage life by adding a gasoline stabilizerthat is formulated for that purpose, or you can avoid fueldeterioration problems by draining the fuel tank and carburetor.

When adding a gasoline stabilizer, fill the fuel tank with freshgasoline. If only partially filled, air in the tank will promote fueldeterioration during storage. If you keep a container of gasolinefor refueling, be sure that it contains only fresh gasoline.

Add gasoline stabilizer following the manufacturers instructions.After adding a gasoline stabilizer, run the engine outdoors for 10minutes to be sure that treated gasoline has replaced theuntreated gasoline in the carburetor.Stop the engine.

If your engine will be stored with gasoline in the fuel tank andcarburetor, it is important to reduce the hazard of gasoline vaporignition. Select a well ventilated storage area away from anyappliance that operates with a flame, such as a furnace, waterheater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.

If possible, avoid storage areas with high humidity, because thatpromotes rust and corrosion.

Keep the engine level in storage. Tilting can cause fuel or oilleakage.

With the engine and exhaust system cool, cover the engine tokeep out dust. A hot engine and exhaust system can ignite or meltsome materials. Do not use sheet plastic as a dust cover.A nonporous cover will trap moisture around the engine,promoting rust and corrosion.

Gasoline is highly flammable and explosive, and youcan be burned or seriously injured when handlingfuel.

If the cylinder was coated with oil during storage preparation, theengine will smoke briefly at startup. This is normal.

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

If equipped with a battery for electric starter types, recharge thebattery once a month while the engine is in storage.This will help to extend the service life of the battery.

If the engine has been running, allow it to cool for at least 15minutes before loading the engine-powered equipment on thetransport vehicle. A hot engine and exhaust system can burn youand can ignite some materials.

If the fuel was drained during storage preparation, fill the tank withfresh gasoline. If you keep a container of gasoline for refueling, besure it contains only fresh gasoline. Gasoline oxidizes anddeteriorates over time, causing hard starting.

Keep the engine level when transporting to reduce the possibilityof fuel leakage. Turn the fuel valve to the OFF position (seepage ).


Wipe up spills immediately.Handle fuel only outdoors.

Pull the starter rope slowly until resistance is felt and the notchon the starter pulley aligns with the hole at the top of the recoilstarter cover. This will close the valves so moisture cannot enterthe engine cylinder. Return the starter rope gently.

Reinstall the spark plug.

Pull the starter rope several times to distribute the oil in thecylinder.

Pour a teaspoon 5 10 cm (5 10 cc) of clean engine oil into thecylinder.

Remove the spark plug (see page ).

Change the engine oil (see page ).

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

Remove the carburetor drain bolt and gasket. Remove thesediment cup and O-ring, then move the fuel valve lever to theON position.

Place an approved gasoline container below the carburetor, anduse a funnel to avoid spilling fuel.

Move the fuel valve lever to the OFF position.

Replacement Parts

Problems That May Affect Emissions

Tampering and Altering

The U.S., California Clean Air Act, and Environment Canada

17

The combustion process produces carbon monoxide, oxides ofnitrogen, and hydrocarbons. Control of hydrocarbons and oxidesof nitrogen is very important because, under certain conditions,they react to form photochemical smog when subjected tosunlight. Carbon monoxide does not react in the same way, but itis toxic.

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 1,500 meters (5,000 feet) with a modifiedcarburetor may cause the engine to overheat and result in seriousengine damage. For use at low altitudes, have your servicingdealer return the carburetor to original factory specifications.

Even with carburetor modification, engine horsepower willdecrease about 3.5% for each 300 meter (1,000 foot) increase inaltitude. The effect of altitude on horsepower will be greater thanthis if no carburetor modification is made.

High altitude performance can be improved by specificmodifications to the carburetor. If you always operate your engineat altitudes above 1,500 meters (5,000 feet), have your servicingdealer perform this carburetor modification. This engine, whenoperated at high altitude with the carburetor modifications forhigh altitude use, will meet each emission standard throughout itsuseful life.

At high altitude, the standard carburetor air-fuel mixture will betoo rich. Performance will decrease, and fuel consumption willincrease. A very rich mixture will also foul the spark plug andcause hard starting. Operation at an altitude that differs from thatat which this engine was certified, for extended periods of time,may increase emissions.

Honda utilizes appropriate air/fuel ratios and other emissionscontrol systems to reduce the emissions of carbon monoxide,oxides of nitrogen, and hydrocarbons.Additionally, Honda fuel systems utilize components and controltechnologies to reduce evaporative emissions.

Follow the maintenance schedule on page . Remember that thisschedule is based on the assumption that your machine will beused for its designed purpose. Sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions,will require more frequent service.

A manufacturer of an aftermarket part assumes the responsibilitythat the part will not adversely affect emission performance. Themanufacturer or rebuilder of the part must certify that use of thepart will not result in a failure of the engine to comply withemission regulations.

The emission control systems on your Honda engine weredesigned, built, and certified to conform with EPA, California(models certified for sale in California), and Canadian emissionregulations. We recommend the use of Honda Genuine partswhenever you have maintenance done. These original-designreplacement parts are manufactured to the same standards as theoriginal parts, so you can be confident of their performance. Theuse of replacement parts that are not of the original design andquality may impair the effectiveness of your emission controlsystem.

Black exhaust smoke or high fuel consumption.Afterburning (backfiring).Misfiring or backfiring under load.Rough idle.Hard starting or stalling after starting.

If you are aware of any of the following symptoms, have yourengine inspected and repaired by your servicing dealer.

Altering or defeating the governor linkage or speed-adjustingmechanism to cause the engine to operate outside its designparameters.

Removal or alteration of any part of the intake, fuel, or exhaustsystems.

Tampering with or altering the emission control system mayincrease emissions beyond the legal limit. Among those acts thatconstitute tampering are:

The following instructions and procedures must be followed inorder to keep the emissions from your Honda engine within theemission standards.

EPA, California, and Canadian regulations require allmanufacturers to furnish written instructions describing theoperation and maintenance of emission control systems.
