PROLONGED STORAGE

To reduce the possibility of severe injury or death resulting from a possible explosion:
Do not handle fuel in an area that is not adequately ventilated. Do not smoke near the fuel
tank or refuel near open flame or electrical items which could produce a spark.
Store vehicle in a clean, dry area. Do not store in same area as a stove, furnace, water heat-
er, or other appliance that uses a pilot light or has a device that can create a spark.
When refueling, inspect the fuel cap for leaks or breaks that could result in fuel spillage.
Always wear safety glasses while refueling to prevent possible eye injury from gasoline or
gasoline vapor.
Keep hands, clothing and jewelry away from moving parts. Use care not to contact hot
objects. Raise the rear of the vehicle and support on jack stands before attempting to run the
engine.
Preparing the engine for a prolonged storage period (30 days or more) calls for a few simple steps to prevent a build up
of varnish and gum in the carburetor and corrosion in the engine.
•
Raise the rear of the vehicle and support on jack stands. Refer to 'Lifting the Vehicle' for proper lifting procedure
and safety information.
•
Disconnect the fuel hose at the fuel tank and plug hose.
•
With proper ventilation, depress the accelerator pedal and allow engine to run until it stops due to lack of fuel.
•
Remove spark plug and pour about 1 oz. (30 ml) of engine oil into the cylinder. Replace spark plug, ground spark
plug wire and use starter to turn engine over a few seconds to distribute oil.
•
Add a gasoline additive to the tank in accordance with the manufacturer's recommendations.
•
Reattach fuel line to tank and drive the vehicle for several minutes to circulate the additive through the carburetor.

While engine is still warm, change oil.
