Fuel
MPORTANT: It is important to prevent gum deposits from forming in
fuel system parts such as the carburetor, fuel hose or tank during
storage. Alcohol-blended fuels (called gasohol, 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. To avoid engine problems, the fuel system should be
emptied before storage of 30 days or longer. See "Storage" on page 18.
Never use engine or carburetor cleaner products in the fuel tank as
permanent damage may occur.
