Claims

[Scope of utility model registration request]

The slow system fuel passage includes a vertical passage communicating with the float chamber and extending vertically upward, a horizontal passage connecting to the upper end of the vertical passage and extending horizontally, and a slow passage communicating with the horizontal passage and opening near the throttle valve. The horizontal passage communicates with a slow air bleed port that is a large vesti lily formed downstream of the small bench lily in the intake passage and opens below the oil level in the float chamber, In a slow system fuel supply device for a carburetor, a slow jet is provided in the vertical passage, and the air introduced from the slow bleed port is guided to the slow jet and the air-fuel mixture is discharged from the slow port. An atmospheric passage is formed in which a portion above the oil level in the float chamber is communicated with the vicinity of the small bench lily of the intake passage or upstream thereof, and a means is provided for opening and closing this atmospheric passage. Slow system fuel supply device for carburetor.
