Storage
If the engine will be out of service for two months or
more, use the following storage procedure:
1.
2.
3.
4.
5.
Clean the exterior surfaces of the engine. On EFI
engines, avoid spraying water at the wiring
harness or any of the electrical components.
Change the oil and filter while the engine is still
warm from operation. See "Change Oil and Oil
Filter" on page 9.
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 system are empty.
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.
Store the engine in a clean, dry place.
