Adjusting Idle Speed
Engine stops while idling
: Carefully screw the low speed
screw (L) down onto its seat
(clockwise), then turn it one full
turn counterclockwise from that
position.
: Turn the idle speed screw (LA)
slowly clockwise until the chain
begins to run – then turn the screw
back one quarter of a turn from
that position.
Chain runs while engine is idling
: Carefully screw the low speed
screw (L) down onto its seat
(clockwise), then turn it one full
turn counterclockwise from that
position.
: Turn the idle speed screw (LA)
slowly counterclockwise until the
chain stops running – then turn the
screw another quarter of a turn in
the same direction.
Erratic idling behavior, poor
acceleration
(even though L screw is open 1 full turn)
Idle setting is too lean:
: Turn low speed screw (L)
counterclockwise until the engine
runs and accelerates smoothly.
It is usually necessary to change the
setting of the idle speed screw (LA)
after every correction to the low speed
screw (L).
Fine Tuning for Operation at High
Altitude
A slight correction of the setting may be
necessary if engine power is not
satisfactory when operating at high
altitude:
: Check the standard setting.
: Warm up the engine.
: Turn high speed screw (H) slightly
clockwise (leaner) no further than
stop.
