CARBURETOR
ADJUSTMENT
The idle speed of the engine is adjustable through the
Air filter/Muffler
cover (Fig. 29).
NOTE: Careless adjustments
can seriously damage your
unit. Any nonroad engine repair establishment,
individual
or authorized service dealer should make carburetor
adjustments.
Check Fuel Mixture
Old and/or improperly mixed fuel is usually the reason
for the unit not running properly. Drain and refill the tank
with fresh, properly mixed fuel prior to making any
adjustments.
Refer to the Oil and Fuel Mixing
Instructions
in the Operation
section.
Clean Air Filter
The condition of the air filter is important to the
operation of the unit. A dirty air filter will restrict air flow
and change the air/fuel mixture. This is often mistaken
for an out of adjustment carburetor. Check the condition
of the air filter before adjusting the idle speed screw.
Refer to the Oil and Fuel Mixing Instructions in the
Operation
section.
Adjust Idle Speed Screw
WARNING: The cutting attachment
may be
spinning during idle speed adjustments.
Wear
protective clothing and observe all safety
instructions to prevent serious personal injury.
NOTE: The cutting attachment
should not rotate when
the engine idles.
3.
If the cutting attachment rotates when the engine
idles, turn the idle speed screw counterclockwise
1/8
of a turn at a time (as needed), to reduce idle speed.
Checking the fuel mixture, cleaning the air filter, and
adjusting the idle speed screw should solve most
engine problems.
If not and:
• The engine will not idle,
• The engine hesitates or stalls on acceleration,
• There is a loss of engine power, have the carburetor
adjusted by any nonroad engine repair establishment,
individual or authorized service dealer.
_ll
WARNING: When the unit is turned off make sure
the cutting attachment has stopped before the unit
is set down to prevent serious personal injury.
Idle Speed Screw
If after checking the fuel mixture and cleaning the air
filter the engine still will not idle, adjust the idle speed
screw as follows.
1. Start the engine and let it run at a high idle for a minute
to warm up. See Starting/Stopping
Instructions, Pg. 12.
2.
Release the throttle trigger and let the engine idle. If the
engine stops, insert a small phillips or flat blade
screwdriver into the hole in the air filter/muffler cover
(Fig. 29). Turn the idle speed screw in, clockwise, 1/8 of
a turn at a time (as needed) until the engine idles
smoothly.

If the unit will be stored for an extended period of time,
use the following storage procedure.
1. Drain all fuel from the fuel tank and drain into a container with
the same 2-cycle fuel mixture. Do not use fuel that has been
stored for more than 60 days. Dispose of the old fuel/oil mix
in a safe manner and use a fresh mix.
2. Start the engine and allow it to run until it stalls. This ensures
that all fuel has been drained from the carburetor.
3. Under To Fuel Engine in the Operation section of this manual,
refer to the message labeled IMPORTANT,regarding the use of
gasohol in your engine.
Fuel stabilizer is an acceptable alternative in mialmizing the
formation of fuel gum deposits during storage. Add stabilizer to
the gasoline in fuel storage container. Follow the mix
instructions found on stabilizer container. Run engine at least
five (5) minutes after adding stabilizer.
Craftsman®
40:! 2-cycle engine oil is already blended with
fuel stabilizer. If you do not use this Craftsman oil you can
add a fuel stabilizer to your fuel. NEVER add fuel stabilizer
directly to the unit's fuel tank.
4. Allow the engine to cool. Remove the spark plug and put about
1 oz. (30 m{_of any high quality motor oil or 2-cycle oil into the
cylinder. Pull the starter rope slowly to distribute the oil.
:_alnstall t he spark plug.
NOTE: Remove the spark plug and drain all of the oil from the
cy{inder before attempting to start the unit after storage.
5. Thoroughly clean the unit and _nspect for any _oose or
damagee parts. Repair or replace damaged Darts and tighten
loose screws, nuts or bolts. The unit is now ready for storage.
6. Store the unit in a dry, well ventilated area and out of the
reach of children.
