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 gasohot or using
ethanol or metllanol) can attract moisture
which leads to separation and formation
of adds 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 untilthe fue_
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
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 t0 mi0utes
after adding stabilizer to altow the stabilizerto
reach the carburetor. Do not drain the gas
tank and carburetor if using fuel stabi{izer.
