Storage
If engine is stored over 30 days, prepare as follows:
1. To prevent gum from forming in fuel system or on
essential carburetor parts:
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.
If fuel tank contains gasoline either run engine until it
stops from lack of fuel or add a gasoline additive. If you
use a gasoline 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.
WARNING
When storing gasoline or equipment with fuel
in the tank:
• Store away from furnaces, stoves, water
heaters, or other appliances that have a
pilot light or other ignition source because
they can ignite gasoline vapors.
When Transporting Equipment:
• Transport with fuel tank EMPTY or with
fuel shut-off valve OFF.
