An engine-starting air-to-fuel ratio control system is described incorporated with a carburetor for supplying the amount of fuel into an engine according to the amount of intake air. The control system consists of: (a) an engine speed sensor for outputting an engine speed signal; (b) an intake air pressure sensor for outputting an intake air pressure signal; (c) an engine coolant temperature sensor for outputting an engine coolant temperature signal; (d) an intake air temperature sensor for outputting an intake air temperature signal; (e) fuel control means for determining the amount by which fuel is to be increased in response to the detected engine speed signal, the detected intake air pressure signal, the detected engine coolant temperature signal and the detected intake air temperature signal, and for outputting a control signal representative of the amount of fuel to be increased; (f) an actuator associated with the carburetor and activated in response to the control signal outputted from the control means for increasing the amount of fuel to be supplied to the engine through the carburetor.
