Technical features and description
Automatic decompressor
To facilitate engine cranking, the decompression actuator forcefully opens the exhaust valve on the
compression stroke to release compression pressure during engine cranking and prevent pressure
in the cylinder from increasing. As the cranking speed increases, the decompression actuator will
move in the direction of a due to the centrifugal force and the exhaust valve will return to normal
operation.
