STORAGE
FUEL Gasoline will oxidize and deteriorate in storage. Old gasoline will
cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your mower 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 Distributor’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 gasoline stabilizer
that is formulated for that purpose, or you can avoid fuel
deterioration problems by draining the fuel tank and carburetor.
Adding a gasoline stabilizer to extend fuel storage life:
When adding a gasoline 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.
1. Add gasoline stabilizer following manufactures instructions.
2. After adding a gasoline
stabilizer, run the engine
outdoors for 10 minutes to be
sure that treated gasoline has
replaced the untreated gasoline
in the carburetor.
3. Stop the engine, and leave the
throttle lever in the STOP
position. This turns OFF the
fuel valve between the fuel tank
and the carburetor.
