ENGINE
Maintenance, repair, or replacement of the
emission control devices and systems, which
are being done at the customers expense,
may be performed by any non-road engine
repair establishment or individual, Warranty

engine manufacturer's service outlet.
FU EL 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.
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,
o Empty the fuel tank by starting the en-
gine and letting it run until the fuel lines
and carburetor are empty,
o Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
o 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 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.
