ENGINE
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
alternative
in minimizing
the formation
of
fuel
gum
deposits
during
storage.
Add
stabilizer
to gasoline
in fuel tank or storage
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 carburetor.
Do not
empty
the gas tank and carburetor
if using
fuel stabilizer.
