ENGINE
FUELSYSTEM
IMPORTANT; It is important to prevent
gum deposits from forming in essentiai
fuel system parts such as carburetor, fuei
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.
1. Drain the fuel tank.
2. 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 reach
the carburetor. Do not drain the gas tank
and carburetor if using fuel stabilizer.
