CARBURETOR ADJUSTMENT
WARNING:The trimmer head will be
spinning during most of this procedure.
Wear your protective equipment and
observe all safety precautions. After
making mixture adjustments, recheck
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.

at the factory. Adjustments may be
necessary if you notice any of the fol-
lowing conditions:
Engine will not idle. See "Idle Speed"
under adjusting procedure.

accelerating. See "Acceleration
Check" under adjusting procedure.

To adjust presets:
Turn mixture screw counterclockwise
until it stops.
Turn the idle speed screw clockwise
until it stops. Now turn counterclock-
wise 4-1/2 turns.
Start motor, cut grass for 3 minutes,
and proceed to the adjustment
