This is the electric throttle solenoid.  The engine's idle speed is 650 RPM.  When this solenoid is activated the engine speeds up to full throttle, 4,600 RPM.  Even though the engine has been converted to propane, the throttle solenoid is original equipment.

The purpose of the Throttle Solenoid is to move the Engine Carburetor Throttle Valve to the wide open position when supplied a Battery feed by the Throttle Relay "G" and to allow its return to Idle position when the Throttle Relay "G" opens the Circuit. This action is instantaneous and allows for exact timing of the 8 second "ON" and 4 second "OFF" warning cycle operation.
