PURPOSE:To make an igniting charactor for a mixture better and improve a starting charactor by constituting so that an ignition timing upon a cranking is delayed to a timing where a mixing ratio of fuel to air becomes most rich, that means the ignition timing is delayed to proximity of an upper dead-point of the crank. CONSTITUTION:A distributor 1, controlling an ignition timing, is provided with a vacuum ignition angle advancing device 2 and an ignitio angle delaying device 3. The vacuum ignition angle advancing device 2 is constituted so that a rod 6, being connected to a breaker cam plate 5 pivoting relative to a rotating cam 4, is connected to a diaphragm 9 dividing a negative pressure chamber 7 and an atmospheric air chamber 8. The ignition angle delaying device 3 is constituted with the rod 6, at an extended tip portion of which an iron plate 18 is fixed, and an electromagnetic solenoid 19 provided around the rod 6. According to these constitutions, when a starting switch 21 is closed, the electromagnetic solenoid 19 id fed simultaneously and the rod 6 is attracted and moved against a spring 17 together with the iron plate 18, thereby, the plate 5 is pivoted into a direction to delay the igniting angle. |
