ENGINE
FUEL SYSTEM
IMPORTANT:
It is important to prevent
gum deposits from forming in essential fuel
system parts such as carburetor, fuel hose,
or tank during storage. Also, 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.
28
• Empty the fuel tank by starting the engine
and letting it run untilthe 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 foIlowthe mix ratiofound on stabilizer
container. Run engine at least t0 minutes
after adding stabilizer to allowthe stabilizerto
reach the carburetor. Do not empty the gas
tank and carburetor if using fuel stabilizer.
ENGINE OIL

with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual),
CYLINDER(S)

2, Pour one ounce of oil through spark plug
hole(s) into cylinder(s).

OTHER
• Do not store gasoline from one season to
another.

gasoline will cause problems.
• If possible, store yourtractor indoors and
cover it to give protection from dust and
dirt,
• Cover your tractor with a suitable protec-
tive cover that does not retain moisture.
Do not use plastic. Plastic cannot breathe
