ENGINE IGNITION TIMING CONTROL WITH MULTI-STAGE ADVANCES, RETARD, AND ALTITUDE COMPENSATION FUNCTIONS ABSTRACT OF THE DISCLOSURE A multi stage engine ignition timing control providing dual stages of advance movement by the use of carburetor spark port vacuum applied to one diaphragm and engine driven air pump pressure applied to a second diaphragm, and the use of a con- stant reference pressure against one or both of the diaphragms to render the movements independent of barometric pressure changes, and including a one-way coupling to effect a retarded ignition timing setting upon switching of the actuating force acting against the one diaphragm from spark port vacuum to air pump pressure.
