Abstract
A variable venturi-type carburetor comprising a vacuum chamber, connected to a venturi portion of the carburetor, and a suction piston actuated in response to a change in vacuum in the vacuum chamber. A fuel passage is formed in the carburetor and is open to the intake passage of the carburetor. The suction piston has a needle extending through the fuel passage. An air bleed passage is connected to the fuel passage. When the level of vacuum in the intake passage becomes smaller than a predetermined level, the amount of air fed into the fuel passage from the air bleed passage is reduced, and the vacuum chamber is caused to be open to the atmosphere.
