In a low-speed fuel passage 6 of a carburetor that supplies fuel to the main intake passage 1 when the throttle valve 2 is opened at a small opening and uses a low-speed fuel jet 4 having a bleed hole 5, the bleed hole 5, and a second bleed air passage 8, which introduces air downstream of the low-speed fuel jet 4, and operates with the engine's intake negative pressure. When the intake negative pressure during cranking for starting the engine is weak, the first bleed air passage 7 is connected to the atmosphere and the second bleed air passage 8 is isolated from the atmosphere by the switching valve 9; A low-speed fuel passage of a carburetor, characterized in that when the intake negative pressure is strong during engine idling operation, the first bleed air passage 7 is cut off from the atmosphere and the second bleed air passage 8 is made open to the atmosphere.
