b. Adjust governor by means of the fine adjustment screw for 2400 rpm. To do this, loosen high rpm fine
adjustment screw locknut. Turn screw in a clockwise direction to decrease engine speed or in a
counterclock wise direction to increase engine speed.
One turn of the fine adjustment screw will increase or decrease
engine speed approximately 20 rpm.
c. Install upper engine cowl and repeat step 2 to ensure proper rpm setting.
d. After setting proper high rpm adjustment, run self-locking nut on fine adjustment screw against
base projection to lock. e. Ensure that governor control arm is adjusted to proper angle on control
wheel.

(Refer to figure 611.) To adjust control travel, disconnect control cable end from control arm, loosen
cable jam nut and rotate end to obtain desired level clearance. Reconnect cable end and tighten jam
nut.
