Engine Model

Engine Models represents a typical air cooled, side-valve four-stroke petrol engine with the operation of the valves clearly evident. The cams of the Engine Models are driven by a gear train from rear of the main crank. As with the two-stroke model, the Engine Model̢۪s simulated spark plug uses a small lamp to indicate the firing point. Screw terminals are provided for connection to 3 volts battery and the Engine Model is mounted on base.
