FUEL SYSTEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential fuel
system parts such as carburetor, fuel filter,
fuel hose, or tank during storage. Also,
experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage.
• Drain the fuel tank.
• Start the engine and let it run until the fuel
lines and carburetor are empty.
• Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
alternative in minimizing the formation of fuel
gum deposits during storage. Add stabilizer to
gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer

container. Run engine at least 10 minutes
after adding stabilizer to allow the stabilizer to
roach the carburetor. Do not drain the gas
tank and carburetor if using fuel stabilizer.
