ENGINE
FUEL SYSTEM
IMPORTANT." It is important to prevent bum
deposits from forming in essential joel system
parts such as carburetor, fuel filter, fuel hose,
or tank during storabe. Also, experience
indicates that alcolol blinded fuels (called
gasohol or using ethanol or methanol) can
attz'act 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
altemative 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.
ENGINE OIL
Drain oil (with engine warm) and replace with
clean engine oil. (See "ENGINE" in the
Customer Responsibilities section of this
manual).
