A decompression arm 5 is pivotably supported in a tangential direction on a camshaft 2 of a valve train 1 of an engine E near the intake/exhaust cams 3 and 4. The tension of the decompression spring 6 pushes up the tappet 7 to the decompression position A, and the centrifugal force F of the decompression release centrifugal weight 8 causes it to move back to the decompression release position B against the decompression spring 6. In the mechanical automatic decompression device for engine starting configured as above, the base end 11 of the centrifugal weight 8 is connected to the suction/exhaust cam 3.
A fulcrum pin 14 is attached to the side surface 12 of the cam ridge portion 10 of , 4.
A mechanical system for starting an engine, characterized in that a weight part 15 that generates most of the centrifugal force is located at a position 16 offset by about half a rotation from the cam crest part 10. Automatic decompression device. 2. A notch 37 is formed in the side walls of the intake/exhaust cams 3 and 4, and the decompression arm 5 is advanced into the notch 37, so that one end of the decompression arm 5 swings within the notch 37. An automatic mechanical decompression device for starting an engine according to claim 1, characterized in that:
