Abstract: A carburetor having an extended prime fuel chamber for gasoline engines. The carburetor includes a carburetor body having a throat, a fuel bowl, a conduit extending from the fuel bowl to the throat, a variable volume primer chamber communicating with the bowl through a priming passage, and an extended prime fuel chamber. The extended prime fuel chamber delivers additional fuel from start-up through warm-up periods of the engine. The extended prime fuel chamber communicates with the throat extending to the engine and communicates with the bowl containing fuel. The extended prime fuel chamber is arranged such that, after activation of a priming bulb, fuel from the carburetor bowl is directed into the throat through a nozzle tube and also into the extended prime fuel chamber through a prime fill passage.

Abstract: A sealing ring assembly for installation in a single sealing ring groove of a piston that is for use in an internal combustion engine, hydraulic cylinder piston, or the like, and replaces the top and second ring seals as are presently utilized, which sealing ring assembly is for curtailing leakage between the piston outer surface and surface of a cylinder containing the piston. The sealing ring assembly consists of a first, primary or main ring that is for fitting in a piston sealing ring groove and is cut back along top and bottom surfaces to provide slots that are each receive a flat rail fitted therein, with the assembly to be contained within the sealing ring groove. The sealing ring assembly can be manufactured in various widths from one quarter (1/4) inch to one (1) millimeter, and the first, primary or main ring preferably has an end gap cut formed at a ninety (90) degree angle thereacross, and the rails preferably each have an end gap cut formed at a forty-five (45) degree angle thereacross.
