FUEL SYSTEM
Under FUELING ENGINE in the OPERA-
TION section of this manual, see mas-
sage labeled IMPORTANT regarding
the use of gasohol in your engine.
Fuel stabilizer is an acceptable alter-
native in minimizing the formation of
fuel gum deposits during storage. Add
stabilizer to the gasoline in the fuel
tank or fuel storage container. Follow
the mix instructions found on stabilizer
container. Run engine at least 5 min-
utes after adding stabilizer.
Craftsman 40:1, 2-cycle engine oil (air
cooled) is already blended with fuel
stabilizer. If you do not use this Sears
oil, you can add a fuel stabilizer to
your fuel tank.
INTERNAL ENGINE
• Remove spark plug and pour 1 tea-
spoon of 40:1, 2-cycle engine oil (air
cooled) through the spark plug open-
ing. Slowly pull the starter rope 8 to
10 times to distribute oil.
• Replace spark plug with new one of
recommended type and heat range.
• Clean air filter.
