ENGINE
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 alcolol
blended fuels (called gasohol or using
ethanol or methanol) can attract moisture
which leads to separation and forma_on
of acids during storage. Acidic gas can
damage the fuel system of an engine
while in storage.
o Drain the fuel tank.
= Start the engine and let it run until the fuel
lines and carburetor are empty°
o Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
o Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable
aitemative 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 tO minutes
after adding stabilizer to allow the stabilizer to
reach the carburetor. Do not drain the gas
tank and carburetor ifusing fuel stabilizer.
