IMPORTANT: It is important to prevent gum deposits from
forming in essential fuel system parts, such as the carburetor,
fuel filter, fuel hose or tank during storage.Also, experience
indicates that 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 12. Never use engine or carburetor cleaner
products in the fuel tank or permanent damage may occur.
