PURPOSE:To prevent delivery of fuel from governer reliably upon closure of throttle valve is fuel feeder where governor valve is arranged in the downstream of carburetor, by constructing such that the valve mechanism arranged in the fuel path of governor is opened/closed with correspondence to the differential pressure between the up and downstreams of governor. CONSTITUTION:A governor 7 including a fuel path 12 communicatable with float chamber 15 is arranged in the downstream of carburetor 1 while a throttle valve 3 and a governor valve 8 are arranged respectively in the up and downstream of intake path 26. Here, the fuel path 12 is branched through tubular partition chamber containing a sliding valve 20 to high idle hole 13 and high bypass hole 14 and opened to the intake path 26 through said holes 13, 14. Inter-valve pressure chamber 17 and vacuum chamber 19 partitioned in front and rear of the sliding valve 20 in partition chamber are communicated respectively with inter-valve pressure taking port 16 and intake pressure take-out port 18. The sliding valve 20 is constructed to open the fuel path 12 when the pressure P1 in said chamber 17 is higher than the pressure P2 in vacuum chamber 19 and the difference is within predetermined range.
