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).
