III. Fuel System
To avoid stale gas and carburetor problems, treat the fuel
system in the following method below:
NOTES
TecumsehPower Company recommends using
ULTRA-FRESH™
Gasoline Stabilizer as an acceptable
method of minimizing formation of fuel gum deposits during
storage. This product is available from your Authorized
TecumsehPower 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.
IV. 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 engine with fuel in the
fuel tank inside a building with
potential sources of ignition such as hot water or space
heaters, clothes dryers, electric motors, etc. Doing so may
lead to an explosion resulting in death or serious injury.
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.

2. Run the engine while waiting until the remaining fuel is
consumed.

when it is running and NEVER run
engine in enclosed areas to avoid death or serious injury.
