STORING YOUR ENGINE
Storage Preparation
Proper storage preparation is essential for keeping your engine trouble free and looking
good. The following steps will keep rust and corrosion from impairing your engine's
function and appearance, and will make the engine easier to start after storage.
Cleaning
If the engine had 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 ofoil.
NOTE
• 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 of muffler can enter the cylinder.
• Water contacting a hot engine can cause damage. If the engine has been running,
allow it to cool for at least half an hour before washing.
Fuel
Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting and
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
temperature, 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.
