FUEL SYSTEM
IMPORTANT:
It is important
to prevent
gum deposits
from forming
in essential
fuel
system
parts such as carburetor,
fuel filter,
fuel
hose, or tank during
storage.
Alcohol
blended
fuels
(called
gasohol
or using
ethanol
or methanol)
can attract
moisture
which
leads to separation
and formation
of
acids during storage. Acidic gas can damage
the fuel system of an engine while in storage.
• Empty
the fuel tank by starting
the en-
gine and letting it run until the fuel lines
and carburetor
are empty.
• Never use engine
or carburetor
cleaner
products
in the fuel tank or permanent
damage
may occur.
• Use fresh fuel next season.
NOTE:
Fuel stabilizer
is an acceptable
al-
ternative
in minimizing
the formation
of fuel
gum deposits
during storage.
Add stabilizer
to gasoline
in fuel tank or storage
container.
Always followthe
mix ratio found on stabilizer
container.
Run engine
at least 10 minutes
after adding stabilizer
to allow the stabilizer
to
reach the carburetor.
Do not empty the gas
tank and carburetor
if using fuel stabilizer.
