This patent describes a fuel supply control system for a vehicle internal combustion engine having a variable venturi type carburetor with a fixed main nozzle and a variable nozzle in which a higher suction of intake air than a predetermined rate increases the opening area of the variable nozzle. The principal component features of this system are, firstly, a separate first and second fuel supply increasing means connected to the main nozzle for selectively increasing the amount of fuel supplied through it and, secondly, a modality which can cause the first means to increase the fuel supply within a low-speed range of vehicle operation and also effect the first and second means to increase the fuel supply within a high-load range of engine operation.
