Long Term Storage
 Remove the spark plug and pour about
1/4 ounce of -cycle mixing oil into the
cylinder through the spark plug hole.
Slowly pull the recoil starter or times
so oil will evenly coat the interior of the

IMPORTANT!
All stored fuels should be stabilized with a
fuel stabilizer such as STA-BIL™, if
oil with fuel stabilizer is not used.
 Remove the remaining fuel from the fuel
lines and carburetor.
1. Prime the primer bulb until no more
fuel is passing through.
. Start and run the engine until it stops
running.

and could also lead to increased service
and maintenance cost.
