proper equipment and experience to make
any necessary adjustments.

tion of this manual).

nance section of this manual.
3. Be sure that all nuts, bolts, screws,
and pins are securely fastened. In-
spect moving parts for damage, break-
age and wear. Replace if necessary.

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: Fue! 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
Drain oil (with engine warm) and replace
with clean engine oil. (See "ENGINE" in
the Maintenance section of this manual).
CYLINDER

2. Pour one ounce (29 ml) of oi! through
