ABSTRACT:
In a first aspect, a carburetor fuel adjusting device that facilitates control of the quantity of fuel that flows from the fuel chamber to an air intake port of a carburetor by making it possible for the user to adjust an adjustment valve within the limits defined by emission control regulations. The carburetor fuel adjusting device has a cap having two appendages, and an engagement area to engage a valve extension of the fuel adjustment valves of a carburetor. The cap is retained by the retainer in either a disengaged position, or an engaged position wherein the engagement area of the cap becomes attached to the valve extensions. In the engaged position, the adjustment valves can be turned in unison with the cap within a range formed by the angle between the appendages which, when rotated, abut against stoppers. In a second aspect, a retaining plate of elastic material having two retainer holes adapted to receive and retain the pair of adjustment valves in a prescribed adjustment position is laid against an outer surface of the carburetor body. The adjustment valves each have a base-end portion and a small diameter portion, the threads of the base-end portion having an external diameter larger than that of the threads of the small diameter portion. The external diameter of the threads of the base-end portion is also larger than the diameter of each of the retainer holes of the retaining plate such that when the adjustment valve is screwed into the screw hole of the carburetor, the base-end portion cuts threads in the retainer holes of the retaining plate to thereby prevent rotation of the adjustment valve.
