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. On EFI
engines, avoid spraying water at the wiring
harness or any of the electrical components.
2. Change the oil and filter while the engine is still
warm from operation. See Change Oil and Filter
on page 10.
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 rest of
the system. Close fuel shut-off valve when unit is
being stored or transported.
To empty the system, run the engine until the
tank and fuel system are empty.
4. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install the
plugs, but do not connect the plug leads. Crank
the engine two or three revolutions.
