ABSTRACT:
A fuel metering apparatus, for supplying metered fuel to an associated combustion engine, has an idle fuel metering and supply system comprising adjustable valving means which, in turn, comprises a discharge orifice means and cooperating valving member which is adjustably selectively positioned with respect to such orifice means in order to thereby establish a desired metered rate of fuel flow through the thusly determined effective flow area of the orifice means for a particular pressure differential thereacross; the adjustable valving member is generally contained within a cooperating body member or portion and access to the valving member, subsequent to it being selectively positioned, is prevented by a closure member or sealing plug placed in position after the said selective positioning of said valving member; the sealing plug is formed as by a hardened metal disc and caged within a body which body is held by the cooperating body member containing the valving member; relative rotation as between the caging body and the hardened disc is permitted thereby making drilling through the disc impossible.
