Adjustment if engine does not activate
Set the adjustable parts as specified according to the
following procedure.
1. Loosen the throttle valve adjust screw until the
throttle valve becomes completely free, then turn
the screw clockwise until the regulated angle is
attained.
(Refer to "6-1 Specifications- Adjustment Angle for
Engine Start".)
2. Turn the idling limiter (L-needle) counterclockwise
until it becomes free. (When the needle screw
completely loosens, a click tone can be heard.)
Turn the idling limiter clockwise from this position
until the regulated angle is attained.
(Refer to "6-1 Specifications- Adjustment Angle for
Engine Start- L-needle Adjustment Angle".)
When tightening the L-needle clockwise,
never excessively tighten it.
Doing so may cause damage to the needle
surface resulting in excessive or inconsistent
fuel supply.
