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
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 for 30
days or longer. Drain thegas tank, start the
engine and let it run until the fuel lines and
carburetor are empty . Use fresh fuel next
season. See STORAGE section for addi-
tional information.
