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.
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.
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
deterioration 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 the
Distributor’s Limited Warranty.
You can extend fuel storage life by adding a gasoline stabilizer
that is formulated for that purpose, or you can avoid fuel
deterioration problems by draining the fuel tank and carburetor.
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.
Add gasoline stabilizer following the manufacturer’s instructions.
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.
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be hot. Allow it to
cool before servicing the spark arrester.
Your engine is not factory-equipped with a spark arrester. The
spark arrester is optional part. In some areas, it is illegal to operate
an engine without a spark arrester. Check local laws and
regulations. A spark arrester is available from authorized Honda
servicing dealers.
Remove the 6 mm flange bolts from the muffler protector, and
remove the muffler protector.
Remove the special screws from the spark arrester and remove
the spark arrester from the muffler.
Use a brush to remove carbon deposits from the spark
arrester screen. Be careful to avoid damaging the screen.
The spark arrester must be free of breaks and holes. Replace
the spark arrester if it is damaged.
Install the spark arrester and muffler protector in the reverse
order of disassembly.
Stop the engine, and if the fuel tank is equipped with a fuel
valve, move the fuel valve to the CLOSED or OFF position.
