PROBLEM TO BE SOLVED: To obtain a low speed fuel system device for carburetor which can reduce the manufacturing cost, as well as can feed a low speed fuel (a low speed mixture) into a suction passage stably. SOLUTION: The longitudinal axial core line X-X of a low speed passage 12 is provided on a straight line, and a low speed fuel jet 13 and a low speed bleed pipe 14 are provided directing from the upstream side to the downstream side. The upstream end 12A of the low speed passage 12 is provided to open near a main fuel jet 5 under the constant liquid level Y-Y of a float chamber 8, The downstream end 12B of the low speed passage 12 is connected to open directly in a bypass chamber 9.
