fuel to prevent gum from forming in fuel system or on essential
carburetor parts.

storage container. Run engine for a short time to circulate
Additive through carburetor. Engine and fuel can be stored up to
24 months.
Note: If Additive is not used or if engine is operating on gasoline
containing alcohol, e.g. gasohol, remove all fuel from tank and
run engine until it stops from lack of fuel.
