AIR CLEANER
A dirty air cleaner will restrict air flow to the carburetor and cause poor engine performance. Inspect the air
cleaner each time the engine is operated. You will need to clean the air cleaner more frequently if you
operate the engine in very dusty areas.
Operating the engine without an air cleaner, or with a damaged air cleaner, will allow dirt to enter
the engine, causing rapid engine wear. This type of damage is not covered under the Warranty.
Inspection
1.Remove the air cleaner cover. Be careful to prevent dirt and debris from falling into the air cleaner base.
2.Remove the air cleaner from the air cleaner base.
3.Inspect the air cleaner elements. Replace any damaged elements. Clean or replace dirty elements.

For good performance, the spark plug must be properly gapped and free of deposits.
1.Disconnect the cap from the spark plug, and remove any dirt from the spark plug area.
2.Use the proper size spark plug wrench to remove the spark plug.
3.Inspect the spark plug. Replace it if damaged, badly fouled, if the sealing washer is in
poor condition, or if the electrode is worn.
4.Measure the electrode gap with a suitable gauge. The correct gap is(0.60 0.70 mm). If adjustment is
needed, correct the gap by carefully bending the side electrode.
5.Install the spark plug carefully, by hand, to avoid cross-threading.
6.After the spark plug is seated, tighten with the proper size spark plug wrench to compress the washer.
7.When installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.
8.When reinstalling the original spark plug, tighten 1/8 1/4 turn after the spark plug seats to compress the
washer.
A loose spark plug can become very hot and can damage
the engine. Over tightening the spark plug can damage the threads in the cylinder head.

HELPFUL TIPS & SUGGESTIONS STORING YOUR
ENGINE
Storage Preparation
Proper storage preparation is essential for keeping your engine trouble free and looking
good. The following steps will help to keep rust and corrosion from impairing your
engine's function and appearance, and will make the engine easier to start when you use it
again.
Cleaning
If the engine has been running, allow it to cool for at least half an hour before cleaning. Clean
all exterior surfaces, touch up any damaged paint, and coat other areas that may rust with a
light film of oil.
Using a garden hose or pressure washing equipment can force water into the air
cleaner or muffler opening. Water in the air cleaner will soak the air filter, and water
that passes through the air filter or muffler can enter the cylinder, causing damage.

Fuel
Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline will cause hard starting, and it
leaves gum deposits that clog the fuel system. If the gasoline in your engine deteriorates during storage,
you may need to have the carburetor, and other fuel system components, serviced or replaced.
The length of time that gasoline can be left in your fuel tank and carburetor without causing functional
problems will vary with such factors as gasoline blend, your storage temperatures, and whether the fuel
tank is partially or completely filled. The air in a partially filled fuel tank promotes fuel deterioration. Very
warm storage temperatures accelerate fuel deterioration. Fuel problems may occur within a few months,
or even less if the gasoline was not fresh when you filled the fuel tank.
Fuel system damage or engine performance problems resulting from neglected storage preparation are
not covered under Warranty.
ADDING AGASOLINE STABILIZER TO EXTEND FUEL STORAGE LIFE
When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If only partially filled, air in the tank
will promote fuel deterioration during storage. If you keep a container of gasoline for refueling, be sure that
it contains only fresh gasoline.
1.Add gasoline stabilizer by following the manufacturer's instructions.
2.After adding a gasoline stabilizer, run the engine outdoors for 10
minutes to be sure that treated gasoline has replaced the untreated
gasoline in the carburetor.
DRALNING THE FUEL TANK AND CARBURETOR
WARNING
Gasoline is highly flammable and explosive, and you can be burned or seriously injured when
handling fuel.
.Stop engine and keep heat, sparks, and flame away.
.Refuel only outdoors.
.Wipe up spills immediately.
1.Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel.
2.Remove the drain bolt, then move the fuel valve lever to the
ON position.
3.After all the fuel has drained into the container, reinstall the drain bolt and washer. Tighten the drain
bolt securely.

Engine Oil
1.Change the engine oil (see page 10).
2.Remove the spark plug (see page 12).
3.Pour a tablespoon (5 - 10 cc ) of clean engine oil into the cylinder.
4.Pull the recoil starter several times to distribute the oil.
5.Reinstall the spark plug.
Clean fuel strainer
WARNING
Gasoline is extremely flammable and is explosive under Certain conditions Do not
smoke or allow flames or sparks in the area
Remove the fuel strainer from the fuel tank and fuel line.
Clean the fuel strainer(remove dirt which has accumulated on the mesh, and check that the
mesh is not broken anywhere).
Reinstall the fuel strainer and fuel line.
A:Fuel strainer
Storage precautions
If your engine will be stored with gasoline in the fuel tank and carburetor, it is important
to reduce the hazard of gasoline vapor ignition. Select a well-ventilated storage area
away from any appliance that operates with a flame, such as a furnace, water heater, 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 that promotes rust and corrosion.
Keep the engine level in storage. Tilting can cause fuel or oil Leakage
With the engine and exhaust system cool, cover the engine to keep out dust. A hot engine and exhaust
system can ignite or melt some materials. Do not use sheet plastic as a dust cover. A nonporous
cover will trap moisture around the engine, promoting rust and corrosion.

16
Removal From Storage
Check your engine as described in the BEFORE OPERATION CHECKS section of this manual (see page
5).
If the fuel was drained during storage preparation, fill the tank with fresh gasoline. If you keep a container
of gasoline for refueling, be sure it contains only fresh gasoline. Gasoline oxidizes and deteriorates
over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at startup. This
is normal.
TRANSPORTING
Keep the engine level when transporting to reduce the possibility of fuel leakage.

TECHNICAL & CONSUMER INFORMATION
TECHNICAL INFORMATION
Serial Number Location
A: Serial number location
Record the engine serial number in the space below. You will need this information when
ordering parts and when making technical or warranty inquiries.
Carburetor Modifications for High Altitude Operation
At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will
decrease, and fuel consumption will increase.
A very rich mixture will also foul the spark plug and cause hard operation at an altitude that differs from
that at which this engine was certified, for extended periods of time, may increase emissions. Starting.
High altitude performance can be improved by specific modifications to the carburetor. If you always
operate your engine at altitudes above 5,000 feet (1,500 meters), have authorized servicing dealer
perform this carburetor modification. This engine, when operated at high altitudes with the carburetor
modifications for high altitude use, will meet each emission standard throughout its useful life.
Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000 feet (300
meters) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor
modification is made.
When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for
low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may
cause the engine to overheat and result in serious engine damage. For use at low altitudes, have an
authorized servicing dealer return the carburetor to original factory specifications.
