CARBURETOR ADJUSTMENTS
The chain will be moving during most of this
procedure. W ear your protective equipment
and observe all safety precautions. The
chain must not move at idle speed.
The carburetor has been carefully set at the
factory . Adjustm ents may be necessary if
you notice any of the following conditions:
S Chain moves at idle. See IDLE SPEED--T
adjusting procedure.
S Saw will not idle. See IDLE SPEED--T ad-
justing procedure.

is too fast. If the engine stalls, idle is too slow.
Adjust speed until engine runs without chain
movement (idle too fast) or stalling (idle too
slow).

crease engine speed.
S Turn idle speed screw (T) counterclock-
wise to decrease engine speed.If you re-
