摘要： A carburetor comprises a jet needle (7) which has a taper portion gradually decreasing in diameter toward its head and which is inserted in a main nozzle (3) which is provided crossing with an intake pass and provided with a main jet (13) at its lower end. A gap between said main nozzle (3) and said jet needle (7) is allowed to change so as to control the flow of a fuel taken in from the head of the jet needle (7). The lower end of the main jet (13) fixedly provided on the head of said main nozzle (3) comprises a conical surface (16) and a planar portion (17). The main jet (13) has a plurality of downward oblique holes (18) boredly provided on said conical surface (16) in such a manner that the holes are equally spaced on the circumference at an inclined angle 30 to 90 ° to axial direction. The internal surface of said oblique holes (18) is made a rough surface (19).
