ABSTRACT:
A fuel supply control system for a vehicle engine carburetor and particularly a carburetor that includes a variable venturi portion and fixed venturi or nozzle portion. The system includes a fuel valve for supplying additional fuel to the nozzle under low speed or high load conditions sensed by elements responsive to those conditions. The system also includes an air valve for controlling the air supplied to the nozzle and a sensor for closing the air valve to thereby also increase the fuel supplied to the nozzle under high load conditions. Other sensors of engine temperature also control the operation of the fuel and air valves.
