PROBLEM TO BE SOLVED: To reduce a wear in the initial use so as to aim at reduction of labor for readjustment by forming the tip end part of an adjusting screw in a semi- spherical shape and forming the slant upper surface of a groove in a circular bend equal to or slightly larger radius than that of the tip end part. ;SOLUTION: An adjusting screw 16 is screw-mounted sideways from the outside on the upper part of a carburetor main body and a tip end part 17 projecting in its suction passage is formed in a semi-spherical shape and so arranged as to fit in a groove 14 to touch a slant upper surface 15. By turning this adjusting screw 16 for making the tip end part 17 to advance/retreat, so as to change its contact position to the slant upper surface 15 so that the most descent position of a sliding valve 5, namely, an idle position may be adjusted. Since the tip end part 17 and the slant upper surface 15 are formed in mutually resemble curved surface shapes, a very slight wear may cause a surface contact state with a large contact surface. In addition, even throughout he adjusting screw 16 and the groove 14 are not positioned on the same central lines, a stop takes place at the idle position correctly. Thereby, a wear in the initial use is reduced so as to aim at reduction of labor for readjustment.;COPYRIGHT: (C)1997,JPO
