Storage
If the engine will be out of service for two months or
more, use the following storage procedure:
1. Clean the exterior surfaces of the engine.
2. Change the oil and filter while the engine is still
warm from operation. See "Change Oil and Oil
Filter" on page 9.
3. The fuel system must be completely emptied, or
the gasoline must be treated with a stabilizer to
prevent deterioration. If you choose to use a
stabilizer, follow the manufacturers
recommendations, and add the correct amount for
the capacity of the fuel system. Fill the fuel tank
with clean, fresh gasoline. Run the engine for 2-3
minutes to get stabilized fuel into the carburetor.
To empty the system, run the engine until the fuel
tank and system are empty.
4. Remove the spark plug. Add one tablespoon of
engine oil into the spark plug hole. Install the plug,
but do not connect the plug lead. Crank the engine
two or three revolutions.
5. Remove the spark plug. Cover the spark plug hole
with your thumb, and turn the engine over until the
piston is at the top of its stroke. (Pressure against
thumb is greatest.) Reinstall the plug, but do not
connect the plug lead.
6. Store the engine in a clean, dry place.
