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.

Governor and decelerator control linkage

A power unit including a liquid-cooled engine, a radiator in fluid communication with the engine for cooling engine coolant, a fan on one side of the radiator for directing air therethrough, and a noise suppressing baffle on the other side of the radiator for altering the path of travel of air exiting the radiator and absorbing fan noise including a housing containing, noise suppressing material. The housing includes the improvement wherein a perforated panel faces the side of the radiator opposite the fan and is slightly spaced therefrom with the panel being pyramid-shaped and extending toward the radiator and presenting at least three generally planar surfaces intersecting at a common point to the radiator.
