clean approved containers A container with a capacity involving an engine always give the Model
of 2 gallons or less with a pouring spout is Specification and Serial Numbers of the engine
recommended Such a container is easier to handle
and helps eliminate spillage during refueling The engine identification numbers appear on decal or
decals affixed to the engine shrouding Include letter
Do not use gasoline left over from the previous suffixes if there are any
season to minimize gum deposits in your fuel system
and to insure easy starting Record your engine identification numbers on the
