Claims

[Scope of utility model registration request]

A throttle valve disposed in the intake passage, a venturi part provided in the intake passage upstream of the throttle valve, a main fuel passage communicating the venturi part and the fat chamber, and when the throttle valve is at the idle opening position. In a dispute that has an integrated idle port and bypass port that open on the wall surface of the intake passage at the peripheral edge of the throttle valve, and a low-speed fuel flow that communicates the integrated idle port and bypass port with the float chamber, A fuel adjustment screw that can change the area,
A carburetor characterized by being installed directly on the throttle body.
