Fuel - Honda HS724 Owner's Manual

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 snowblower 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 deteriora-
tion. 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 fuel stabilizer that is formulated
for that purpose, or you can avoid fuel deterioration problems by draining the
fuel tank and carburetor.
