Adjusting Idle Speed
Engine stops while idling
:
Open the low speed screw (
L

turn.
:
Turn the idle speed screw (
LA
)
slowly clockwise until the chain
begins to run – then turn the screw

:
Open the low speed screw (
L
)
1/4 turn.
:
Turn the idle speed screw (
LA
)
slowly counterclockwise until the
chain stops running – then turn the
screw another 1/2 turn in the same
direction.

Erratic idling behavior, poor
acceleration
(although L screw is open 1/4 turn)
Idle setting is too lean:
:
Turn low speed screw (
L
)
counterclockwise – no further than
stop – 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
).
