Abstract:
A carburetor in which no deviation or change occurs in the adjusted position of a fuel regulating needle valve and when a cap for limiting the adjustment is mounted on the fuel regulating valve the cap cannot be intentionally broken or removed. A flow area of a fuel pasage of a carburetor body is adjusted by a needle valve received in a threaded hole in the body. Adjacent the threaded hole the carburetor body has a cylindrical cavity having a larger diameter than that of the threaded hole. A larger-diameter threaded portion is provided on the needle valve adjacent its head. A stop ring in contact with a shoulder in the cylindrical cavity is fitted on the larger-diameter threaded portion of the valve. A cup-shaped cap is fitted on the serrated head of the fuel regulating valve. An axial protrusion formed on the outer peripheral wall of the cap is engaged with an axial groove opening into the peripheral wall of the cylindrical cavity. A retaining plate having an opening through which the cap can be inserted is fixed to the outer end wall of the cylindrical cavity of the carburetor body.
