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 (CW) until the regulated angle
is attained.
(Refer to page 15 "5. Carburetor Specifications-
Adjustment Angle for Engine Start- Throttle Valve
Adjust Screw".)
2. Turn the idling limiter (L-needle) counterclockwise
(CCW) until it becomes free. (When the needle
screw completely loosens, a click tone can be
heard.) Turn the idling limiter clockwise (CW) from
this position until the regulated angle is attained.
(Refer to page 15 "5. Carburetor Specifications-
Adjustment Angle for Engine Start- L-needle
Adjustment Angle".)
3. Start the engine and execute the rich down
adjustment.
(Refer to page 23 "Rich Down Adjustment".)
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.
Caution:
If the engine still does not start, problems may
exist elsewhere than the carburetor. Check
those other causes.
