that clog the fuel system. If the gasoline in your
engine deteriorates during storage, you may
need to have the carburetor and other fuel
system components serviced or replaced.
The length of time that gasoline can be left in
your fuel tank and carburetor without causing
functional problems will vary with such factors
as gasoline blend, your storage temperatures,
and whether the fuel tank is partially or
completely filled. The air in a partially filled fuel
tank promotes fuel deterioration. Very warm
storage temperatures accelerate fuel
deterioration. Fuel deterioration problems may
occur within a few months, or even less if the
gasoline was not fresh when you filled the fuel
tank.
The Manufacturer's Limited Warranty does not
cover fuel system damage or engine
performance problems resulting from neglected
storage preparation.
You can extend fuel storage life by adding a
fuel stabilizer that is formulated for that
purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and
carburetor.

When adding a fuel stabilizer, fill the fuel tank
with fresh gasoline. If only partially filled, air in
the tank will promote fuel deterioration during
storage. If you keep a container of gasoline for
refueling, be sure that it contains only fresh
gasoline.
Add fuel stabilizer following the
manufacturer's instructions.
After adding a fuel stabilizer, run the engine
outdoors for 10 minutes to be sure that treated
gasoline has replaced the untreated gasoline in
the carburetor.
Stop the engine, and move the fuel valve to
the OFF position.

Place an approved gasoline container below
the carburetor, and use a funnel to avoid
spilling fuel.
Remove the carburetor drain bolt, and then
pull out the fuel tube.
After all the fuel has drain into the container,
reinstall the drain bolt and fuel tube. Tighten
them securely.

Change the engine oil.
Remove the spark plugs.
Pour a tablespoon (5-10 cc) of clean engine
oil into the cylinder.
Pull the starter rope several times to distribute
the oil in the cylinder.
Reinstall the spark plugs.
Pull the starter rope slowly until resistance is
felt. This will close the valves so moisture
cannot enter the engine cylinder. Return the
starter rope gently.
If your engine will be stored with gasoline in the
fuel tank and carburetor, it is important to
reduce the hazard of gasoline vapor ignition.
Select a well-ventilated storage area away from
any appliance that operates with a flame, such
as a furnace, water heater, or clothes dryer.
Also avoid any area with a spark-producing
electric motor, or where power tools are
operated.
If possible, avoid storage areas with high
humidity, because that promotes rust and
corrosion.
Be sure all fuel has been drained from the fuel
tank, to reduce the possibility of fuel leakage.
