4. After setting the proper high RPM adjustment, run the self-locking nut on the fine
adjustment screw against the base projection to lock.
d. With the high RPM adjustment complete, the control system should be adjusted so that the
governor control arm will contact the high RPM stop when the cockpit control knob is .032 to .047 of an
inch from its full forward stop. To adjust the control knob travel, disconnect the control cable end from
the control arm; loosen the cable end jam nut and rotate the end to obtain the desired level clearance.
Reconnect the cable end and tighten jam nut.
e.
It
is usually only necessary to adjust the high RPM (low pitch) setting of the governor control
system, as the action automatically takes care of the positive low RPM (high pitch) setting.
