。 A suction piston that changes a bench lily area according to the amount of intake air, a needle fixed to the tip of the suction piston, a fuel passage extending in the axial direction of the needle, and a fuel passage provided in the fuel passage and connected to the needle. In a variable vent lily type carburetor equipped with a cooperating metering jet and an air bleed passage opening into the metering jet, the metering jet is formed in two stages in the direction of the fuel passage, and the first stage metering jet is connected to the fuel passage. A second stage metering jet is formed as an insert fitted into the hollow pipe-like member, and the air bleed member is integrally formed as an annular protrusion projecting inwardly into the hollow pipe-like member forming the passage. The passageway is the first and second stage.
A variable bench lily type carburetor, characterized in that a through hole is formed through the hollow wall of the hollow pipe-like member between the metering jets of the stages.
