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 oil fi lter while the engine is
still warm from operation. See Change Oil and
Oil Filter in Section 6.
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 manufacturer’s
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 to 3 minutes to get stabilized
fuel into the rest of the system. Close the fuel
shut-off valve when the unit is being stored or
transported.
To empty the system, run the engine until the
tank and the system is empty.
4. Remove the spark plugs. Add one tablespoon of
engine oil into each spark plug hole. Install plugs,
but do not connect the plug leads. Crank the
engine two or three revolutions.
5. Disconnect the negative (-) ba ery cable or use a
ba ery minder trickle charger while the unit is in
storage.
6. Store the engine in a clean, dry place.
