A variable venturi-type carburetor comprising a suction piston which has a tip face defining a venturi portion. The tip face has a needle-mounting face at the center thereof, and a metering needle is fixed onto the needle-mounting face. The tip face also has a projecting tip face portion located upstream of the needle and projecting from the needle-mounting face towards the venturi portion. A groove, extending along the axis of the intake passage of the carburetor, is formed on the projecting tip face portion. The projecting tip face portion has a V-shaped cross-section which expands from the groove towards the venturi portion.
