ABSTRACT:
A governor control linkage having a first manually operated actuator and a second manually operated actuator provides for setting of an engine governor control arm at a particular operating position by means of the first manually operated actuator, a coupling and an extensible link interconnected with the governor control arm. The coupling operatively locks the first manually operated actuator relative the setting of the governor control arm while allowing the second actuator to temporarily reposition the governor control arm at an intermediate setting. The extensible link in the first manually operated actuator returns the governor control arm and the second manually controlled actuator to the prepositioned setting upon release of the second actuator.
