STORAGE
Engines stored over 30 days need special attention.
[1]
To prevent gum from forming in fuel system or on essential
carburetor parts:
a) if fuel tank contains oxygenated or reformulated gasoline
(gasoline blended with an alcohol or an ether), run engine
until it stops from lack of fuel, or b) if fuel tank contains
gasoline, either run engine until it stops from lack of fuel, or add
a gasoline additive to the gas in the tank. (See parts list.
Single-use pouches of gas additive are available from your
service dealer.) If you use a gas additive, run the engine for
several minutes to circulate the additive through the carburetor.
Then, engine and fuel can be stored up to 24 months.
[2] While engine is still warm, change oil.
[3] Remove spark plugs and pour about 1 oz. (30 ml) of engine
oil into each cylinder. Replace spark plugs and crank slowly
to distribute oil.
[4] Clean engine of surface debris, chaff or grass.
[5] Store in a clean, dry area. Do not
store in same area as a stove,
furnace, water heater, or other
appliance that uses a pilot light or
has a device that can create a
spark.
