ENGINE
FUEL SYSTEM
IMPORTANT: it is important to prevent gum
deposits from forming in essentia! fuel system
parts such as carfoureior; fuel filter, fuel hose,
or tank during storage. Also, experience
indicates that alcohol blended fuels (called
gasohoi 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 fuei 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.
