The controlled feed and ignition device for internal combustion engines comprises a carburettor having an air feed duct equipped with a controllable regulator valve and having a reduced section, into which leads a flooded fuel feed duct from a constant level chamber, in which there is present a device for varying the flow cross-section of the fuel feed duct, an electronically controllable ignition device and an electronic control unit, adapted for governing the device for varying the flow cross-section of the fuel feed duct as a function of instantaneous operating data about the engine supplied to it from relative sensors, the electronic control unit being moreover adapted for acting upon the ignition device for regulating the spark advance value for the engine ignition, as a function of said instantaneous data supplied from the sensors, for setting optimum operating conditions for said engine.
