ENGINE
FUEL SYS TEM
IMPORTANT: It is important to prevent
gum deposits from forming in essential fuel
system parts such as carburetor, fuel fi lter,
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 car bu re tor are empty.
• Never use engine or carburetor cleaner
prod ucts in the fuel tank or permanent
damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable al-
ternative in min i miz ing the formation of fuel
gum deposits during stor age. Add stabilizer
to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer
container. Run engine at least 10 min utes
after adding stabilizer to allow the stabilizer to
reach the carburetor. Do not empty the gas
tank and carburetor if using fuel stabilizer.
NOTE: FRESH START
cartridge system automatically drips con-
centrated fuel preserver into your fuel tank
and is an acceptable alternative to adding
fuel stabilizer.
