4. 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. (Lower cowl must be removed to accomplish this adjustment.)
5. 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.
