Abstract:
1. A carburetor, comprising, (a) a float system having a float chamber and a float; and (b) a mixing system having a venturi body and a venturi, wherein the venturi communicates with an idle port, a screw hole communicates with the idle port on the venturi body, and an idle adjusting screw having a screw head, a thread body and a concave neck is installed in the screw hole on the venturi body, wherein the idle adjusting screw is joined to the screw hole as a unitary body after the idle adjusting screw is adjusted to a predetermined position, such that a further adjustment of the idle adjusting screw causes the concave neck of the idle adjusting screw to be broken off, thereby preventing the idle adjusting screw of the carburetor from being further adjusted.
