Fuel

Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel deterioration and
oxidation can occur in as little as 30 days and may cause damage to
the carburetor and/or fuel system. Please check with your servicing
dealer for local storage requirements.
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 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.
