FUELSYSTEM

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 gasohol or using ethanol or methanol) can attract moisture which leads to separ'_on and formation of acids during storage. Ac'_licgas can damage the fuel system of an engine while in storage.

•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.

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.
