Injection Pump Controller

The pump control system uses a controller, and a connecting rod linking the controller to the injection pump control lever. A control unit is also used and is wired to the ignition switch.

When the ignition switch is in the "START" position, the gears in the assembly rotate, moving the injection pump control lever to a rich fuel condition. This aids engine starting. When the ignition switch is turned to "OFF" position, the lever is moved to a position of no fuel delivery, and the engine stops. During normal engine operation, the system maintains a normal mixture.

If the engine fails to stop, when the ignition switch is turned to the "OFF" position, it can be stopped manually. To do so, turn ignition switch to "OFF" position. Pull control lever away (outward) from injection pump. This disengages the control lever from the pump lever pin. By hand, move the pump lever counterclockwise to the stop position.
