ABSTRACT:
Disclosed herein is an improvement in a variable venturi carburetor for an internal combustion engine including a fuel discharging main nozzle arranged in a venturi portion and a suction piston arranged in an opposite side of the main nozzle for reciprocating in response to the variation of negative pressure of air induced to the engine generated at the venturi portion and varying an area of an induction passage of the venturi portion. The improvement includes that a fore-most end of the main nozzle is projected into the venturi portion and a fuel guide member is arranged at a lower portion of the projecting portion of the main nozzle. The fuel guide member serves to guide a flow of liquid fuel when the flow rate of air flowing through the venturi portion is low and the liquid fuel is discharged through the main nozzle.
