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 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 tank promotes fuel deterioration. Very warm storage/temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur within a few months, or even less if gasoline
was not fresh when you filled the fuel tank.
The warranty does not cover fuel system damage or engine performance problems resulting from neglected
storage preparation.
You can extend fuel storage life by adding fuel stabilizer that is formulated for that purpose, or you can avoid fuel
deterioration problems by draining the fuel tank and carburetor.
Adding A Fuel Stabilizer To Extend Fuel Storage Life
When adding a fuel stabilizer, fill the 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 fueling, be sure that it contains only fresh
gasoline.
1. Add fuel stabilizer following the manufacture’s instructions.
2. 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.
Note:
Dry operation will damage the pump
seal. Be sure the pump chamber is filled with water
before starting the engine.
3. Stop the engine, and move the fuel valve to the OFF
position.
