Abstract
A variable venturi type carburetor having a suction piston adapted to be moved toward and away from an opposing wall of the intake barrel in response to a change in the intake air flow rate so as to change the area of the venturi portion. The carburetor has a throttle valve with a tube-formed fuel introduction port through which the space defined at both sides of the throttle valve are communicated with each other. The fuel introduction port is so arranged that its upstream side end opening facing the suction piston is directed toward the wall to which the fuel discharged from the main jet is attached when the opening degree of the throttle valve is small.
