Idle Speed
Allow engine to idle. Adjust speed until
engine runs without stalling.
• Turn idle speed screw clockwise to
increase engine speed if engine
stalls or dies.
• Turn idle speed screw counterclock-
wise to decrease engine speed.
No further adjustments are necessary
if performance is satisfactory.
Mixture Adjustment
CAUTION: Do not operate engine at
full throttle for prolonged periods while
making adjustments as damage to the
engine can occur. Adjust the mixture
screw 1/16 of a turn at a time. A 1/16
turn is about the width of the slot in the
top of the screw.
• Turn the mixture screw clockwise
until the engine has good power
with no hesitation while cutting.
Do not adjust by sound or speed,
but judge by how well the engine
performs while cutting.
• Turn the mixture screw counter-
clockwise if the engine has speed
but dies or lacks power while cutting.
After completing adjustments, check
for acceleration. Reset if necessary.
Acceleration Check
If engine dies or hesitates instead of
accelerating, turn the mixture screw
counterclockwise until you have
smooth acceleration.

FUEL SYSTEM
Under FUELING ENGINE in the OPERA-
TION section of this manual, see mes-
sage labeled IMPORTANT regarding
the use of gasoho] 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
opening. 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

son to another.
