II. Fuel System
To avoid stale gas and carburetor problems, treat the fuel
system in the following method below:
NOTES
Tecumseh recommends using ULTRA-FRESH™
Gasoline Stabilizer plus Fuel System Cleaner as an
acceptable method of minimizing formation of fuel gum
deposits during storage. This product is available from your
Authorized Tecumseh Servicing Dealer.
Always follow mix ratio found on stabilizer container. Failure
to do so may result in equipment damage.
It is not necessary to drain stabilized gas from carburetor.
III. Fuel Treatment
1. Add fuel stabilizer according to manufacturer’s
instructions.
2. Run engine at least 10 minutes after adding stabilizer
to allow it to reach carburetor.
NEVER store the engine with fuel in
the fuel tank inside a building with
potential sources of ignition such as hot water and space
heaters, clothes dryers, electric motors, etc.
NOTE
Instead of using a fuel preservative/stabilizer, you can
empty the fuel tank as described under I. Draining Fuel
instructions. See "B. Extended Storage" instructions.

If you have prepared your fuel for short term storage it is not
necessary to drain fuel that contains stabilizer from your
carburetor. See "A. Short Term/Seasonal Storage"
instructions on page 15.
To avoid severe injury or death,
DO NOT pour fuel from engine or
siphon fuel by mouth.
1. To prevent serious injury from fuel fires, empty fuel tank
by running engine until it stops from lack of fuel. DO
NOT attempt to pour fuel from engine.
2. Run the engine while waiting until the remaining fuel is
consumed.

unattended when it is running and
NEVER run engine in enclosed areas.
