The automatic pressure relieving mechanism is
installed on the camshaft to facilitate a start of the
engine.
When the engine is started, the fly weight (1)
located on the camshaft (7) undergoes a
decompression spring
tension and pushes up the
tappet (3) (exhaust valve side) via the decompression
pin
(6).

(6) Decompression Pin

(7) Camshaft
By so doing, the compression is relieved and the
recoil tension is reduced.
When the engine speed has
reached 1000-1100
rpm,
both the fly weight and the decompression pin
are pressed against the inner wall of the device by
the centrifugal force to permit normal running state.
