ABSTRACT OF THE DISCLOSURE: Spark timing control apparatus for an internal combustion engine includes a delay mechanism which permits rapid action in one direction of a vacuum actuator but prevents too rapid movement in the other direction. Atmospheric air is admitted through a flow restrictor clement formed of porous sintered metal so that the control mechanism including a check valve is prevented from becoming fouled by contact with the air-fuel mixture in the intake passage of the engine.
