Abstract
There is disclosed a starting decompression device for a four-cycle engine for forcedly open an exhaust valve to decompress a combustion chamber. The starting decompression device includes an interlocking means operatively connected to the exhaust valve, a decompression cam member opposed to the interlocking means, and a return spring for urging the cam member towards an inoperative position at which the exhaust valve is closed. In the device, the cam member is automatically returned, at a suitable time during cranking, to close the exhaust valve, thereby mitigating the initial load of cranking and positively starting the engine.
