FUEL SYSTEM
Under FUELING ENGINE in the OPERA-
TiON section of this manual, see mes-
sage labeled IMPORTANT
regarding the
use of gasohol in your engine.
Fuel stabilizer is an acceptable alterna-
tive in minimizing the formation of fuel
gum deposits during storage. Add stabi-
lizer to gasoline in fuel tank or fuel stor-
age container. Follow the mix instruc-
tions found on stabilizer container. Run
engine at least 5 minutes after adding
stabilizer. Craftsman
40:1,2-cycle
en-
gine oil (air cooled) is already blended
with fuel stabilizer.
If you do not use
this Sears oil, you can add a fuel stabi-
lizer to your fuel tank.
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.
• Check entire unit for loose screws,
nuts, and bolts. Replace any dam-
aged, broken, or worn parts.
• At the beginning
of the next season,
use only fresh fuel having the proper
gasoline to oil ratio.
OTHER
• Do not store gasoline from one sea-
son to another.
• Replace your gasoline can if it starts
to rust.
