CARBURETOR ADJUSTMENT
,_WARNING: The trimmer head
or blade will be spinning during most
of this procedure. Wear your protec-
tive equipment and observe all safety
precautions. After making mixture ad-
justments, recheck idle speed. The
trimmer head or blade must not move/
spin at idle speed.
Carburetor adjustment is critical and if
done improperly can permanently
damage the engine as well as the car-
buretor. If you require further assis-
tance or are unsure about performing
this procedure, call our customer as-
sistance help line at 1-800-235-5878.
Old fuel, a dirty air filter, a dirty fuel fil-
ter, or flooding may give the impres-
sion of an improperly adjusted carbu-
retor. Check these conditions before
adjusting the carburetor.
The carburetor has been carefully set
at the factory. Adjustments may be
necessary if you notice any of the fol-
lowing conditions:
• The trimmer head/blade moves at
idle. See IDLE SPEED under adjusting
procedure.
• Engine will not idle. See IDLE SPEED
under adjusting procedure.
• Engine dies or hesitates instead of
accelerating. See ACCELERATION
CHECK under adjusting procedure.

There are three adjustment screws on
the carburetor. The low speed adjust-
ment screw is marked with the letter L,
