TM 5-4240-501-14&P GOV. CONTROLS & CARB. LINKAGE General Section 4 GOV. CONTROLS & CARB. LINKAGE REMOTE CONTROLS In general, there are three types of remote controls: Governor Control, Throttle Control, Choke-A-Matic Control. Fig. 1 to Fig. 6, show the operation of these control systems. See following pages for specific control assemblies and installation hook-up by engine model. Remote Governor Control The Remote Governor control regulates the engine speed by changing the governor spring tension, thus allowing the governor to control the carburetor throttle at all times and maintain any desired speed. Fig. 1. Fig. 1 - Remote Governor Control Remote Throttle Control The Remote Throttle control is used on an engine having a fixed no load governed speed setting such as 3600 or 4000 R.P.M. This control enables an operator to control the speed of an engine, similar to an accelerator used on an automobile. However, when full governed speed is obtained, the governor prevents over speeding and possible damage to the engine. At any point below the governed speed, the throttle is held in a fixed position and the engine speed will vary with the load. See Fig. 2. Fig. 2 - Remote Throttle Control Choke-A-Matic Remote Control On Choke-A-Matic carburetors, the remote control must be correctly adjusted in order to obtain proper operation of the choke and stop switch.
