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,
