4-15 DECOMPRESSION SYSTEM
An automatic decompression mechanism which
opens the exhaust valve before the piston reaches
maximum compression is assembled on the cam-
shaft for easy starting.
During engine operation the decompression sys-
tem is overpowered by centrifugal force and com-
pression is fully utilized to produce power.
