【摘要】A variable venturi-type carburetor comprising a suction piston which has a tip face defining a venturi portion. The tip face has a projecting tip face portion located upstream of the needle and projecting toward 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 toward the venturi portion. A projection, having a V-shaped cross-section, is formed on the inner wall of the intake passage, which faces the tip face of the intake passage, which faces the tip face of the suction piston. The projection enters into the V-shaped cross-section of the projecting tip face portion of the suction piston when the amount of air fed into the cylinder of the engine is small.
