SECTION 8: OFF-SEASON S TORAGE
If unit is to be stored over 30 days, prepare for storage
as follows:
Remove gasoline from carburetor and fuel tank to
prevent gum deposits from forming on these parts
and causing possible malfunction of engine.
WARNING:
Drain fuel into an approved

cigars, pipes, and other sources of ignition prior
to draining fuel.
Run engine until fuel tank is empty and engine stops
due to lack of fuel.

oil through spark plug hole into cylinder. Cover spark
plug hole with rag. Crank engine several times to
