fuel gum deposits during storage. Add
stabilizerto gasoline in fuel tank or stor-
age container. Always follow the mix ratio
found on stabilizer container. Run engine
at least 10 minutesafter adding stabilizer
to allow the stabilizerto reachthe car-
buretor. Do not empty the gas tank and
carburetor if using fuel stabilizer.

tive cover that does not retain moisture.
