ADJUSTING PROCEDURE
CAUTION: DO not force plastic limiter
caps on screws beyond the built-in
stops or damage will occur.
Initial Settings
1. Turn the mixture screw counter-
clockwise until it stops.
2. Turn the idle speed screw clock-
wise until it stops. Then turn coun-
terclockwise 4 1/2 turns.
3. Start motor and let it run for 3 min-
utes, then proceed to adjust
screws according to the instruc-
tions below. If engine performance
at initial settings is acceptable, no
further adjustments are necessary.
If engine does not start, refer to
TROUBLESHOOTING TABLE. If still
unable to remedy situation, call
1-800-235- 5878.
Idle Speed "IDLE"
Allow engine to idle. Adjust speed until
engine runs without stalling.
• Turn IDLE screw clockwise to in-
crease engine speed.
• Turn IDLE screw counterclockwise to
decrease engine speed.
Mixture "MIX"
Allow engine to idle. Then accelerate
the engine and note performance. If
engine hesitates, bogs down, or
smokes during acceleration, turn MIX
screw clockwise in 1/16-turn incre-
ments until performance is satisfactory.
Repeat this procedure as necessary
for proper adjustment. After completing
adjustments, check for acceleration.
Reset if necessary.
Acceleration Check
If engine dies or hesitates instead of
accelerating, turn MIX screw counter-
clockwise until you have smooth accel-
eration.
_IbWARNING: Perform the following
steps after each use:
• Allow engine to cool, and secure the
unit before storing or transporting.
• Store unit and fuel in a well venti-
lated area where fuel vapors cannot
reach sparks or open flames from
water heaters, electric motors or
switches, furnaces, etc.
• Store unit with all guards in place.
Position unit so that any sharp object
cannot accidentally cause injury.
• Store unit and fuel well out of the
reach of children.
SEASONAL STORAGE
Prepare unit for storage at end of sea-
son or if it will not be used for 30 days
or more.
If your unit is to be stored for a period
of time:
• Clean the entire unit before lengthy
storage.
• Store in a clean dry area.
• Lightly oil external metal surfaces.
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 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.
• 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.
