A carburetor for gasoline internal combustion engines includes a generally cylindrical housing having a mixing channel defined by a wall converging to a point of minimum housing diameter and a wall diverging from the point of minimum diameter, an intake air receiving section and a lower section from which the liquid fuel-air mixture is discharged to the cylinders. At least twelve radially spaced liquid fuel supply ports are formed in the mixing chamber immediately below the point of minimum opening. A regulating member formed generally of two frusto-conical sections arranged with their bases end-to-end is mounted for longitudinal movement within the housing. The upper section of the regulating member deflects the intake air toward a gradually enlarging constricted zone which is defined by the upper section of the regulating member and the diverging wall of the mixing chamber and wherein the liquid fuel is mixed with and atomized by the intake air. The lower section of the regulating member and the lower section of the housing define a turbulence zone.
