たことを特徴とする気化器。In the gap formed between the jet needle 2, which is engaged with the intake throttle valve 1 and is displaced along with the displacement of the intake throttle valve IQ), and the jet needle 2 into which the jet needle 2 is inserted. In a carburetor for a spark-ignition internal combustion engine that measures fuel, a rotating valve body is arranged to block intake passages 5a and 5b in a body 4 of the carburetor, and the blocked intake passage 5at5b. The intake throttle valve 1 includes a rotary valve constituted by a conduction passage 6 provided through the valve body so as to conduct the air. By forming a force 14 on the end face and causing the jet needle 2 to follow the cam ε, the jet needle 2 is moved into the intake passage 5at5b and the conduction passage 6 while engaging the intake throttle valve 1 -ts:t. 2. At the same time, the intake throttle valve 1 is retracted. A carburetor characterized in that a fuel discharge port 11 is provided in a portion of the cylinder wall 9 of the body 4 located upstream of the opening 10 of the intake passage 5a on the downstream side.
