IMPORTANT
Experience indicates that alcohol blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads to
separation and formation of acids during stor-
age. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine
problems, empty the fuel system before stor-
age for 30 days or longer. Drain the gas tank,
start the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel next
season. Never use engine or carburetor clean-
er products in the fuel tank or permanent dam-
age may occur. See the STORAGE section for
additional information.
