4 Install fuel cap and wipe up any spilled fuel

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 18. NEVER use engine or
carburetor cleaner products in the fuel tank or
permanent damage may occur.
