Summary:PURPOSE:To prevent the fuel from a slow system from becoming lean at a high temperature by controlling the bleed air quantity of the slow system in response to the temperature. CONSTITUTION:A control valve 40 has a heat sensitive member 15 such as thermo wax and a metering rod 17 operated by an operating rod 29. A primary air bleed 8A is communicated to the first valve port 37 of the control valve 40 with a pipe 20, the second valve port 18 is connected to the passage 14 of the secondary air bleed 8B with a pipe 21 to introduce the clean atmosphere having passed an air cleaner. At a high temperature, the heat sensitive member 15 is expanded and the metering rod 17 is pushed to the right against a spring 19, thereby the valve port area of the first valve port 37 is decreased by the first taper surface 12 and the bleed air quantity to the slow system fuel is likewise decreased. Accordingly, the air-fuel ratio of the slow system is returned to the rich side.
