ABSTRACT:
A carburetor choke plate is rotated by a driver in one direction from its wide open position for cold enrichment and in the opposite direction from its wide open position for stoichiometric air-fuel ratio control. A fast idle cam limits throttle closure during operation in the cold enrichment mode, and a stop limits movement of the main metering rod toward its rich position in the stoichiometric air-fuel ratio control mode. The choke mechanism also positions an idle bleed valve to vary idle air-fuel ratio, and controls a latch to prevent secondary operation, during both the cold enrichment and the stoichiometric air-fuel ratio control modes.
