It has a slow passage that communicates with the atmospheric pressure side on one side and the intake passage through a small hole, and a fuel passage that communicates in the middle of the slow passage, and air from the atmospheric pressure side in the slow passage. In a carburetor that creates a slow mixture with fuel from a fuel passage and supplies the slow mixture to the intake passage through a small hole, the atmospheric pressure side of the slow passage is connected to an independent first air passage and a second air passage. The first air passage is provided with an adjusting means for variably adjusting the cross section of the passage, and the second air passage is provided with a temperature-sensitive valve means for varying the cross section of the passage according to changes in outside air temperature. The change in the cross section of the first air passage and the cross section of the second air passage results in a change in air pressure in the slow passage, and the change in air pressure and the negative pressure in the intake passage from the small hole act on the fuel passage. A mixture ratio automatic correction structure in a carburetor, characterized in that the slow mixture ratio is changed by changing the pressure and changing the amount of fuel from the fuel passage to the slow passage.
