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 gasohot
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 fue! next season_
NOTE;
Fuel stabilizer
is an acceptable
alternative
in minimizing
the formation
of
fuel gum deposits
during storage.
Add
stabilizer
to gasoline
in fuel tank or stor-
age container,
Always
follow the mix ratio
found on stabilizer
container.
Run engine
at least 10 minutes
after adding stabilizer
to allow the stabilizer
to reach the car-
buretor,
Do not empty the gas tank and
carburetor
if using fuel stabilizer.
ENGINE
OIL
