Idle speed adjustment

NOTE:
A diagnostic tachometer must be used for this
procedure.
1. Start the engine and warm it up for a few
minutes at approximately 1,000 to 2,000
r/min. Occasionally rev the engine to 4,000
to 5,000 r/min. The engine is warm when it
quickly responds to the throttle.
2. Connect the tachometer tachometer to the
spark plug lead, and then set the idle to the
specified idling speed by adjusting the throt-
tle stop screw. Turn the screw in to direction
a to increase the engine speed, and out in
direction b to decrease the engine speed.
Specified idle speed:
1,450 ~1,550 r/min
8-51
