IMPORTANT:
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.
