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. Once the engine fires, the fuel in the extended prime fuel chamber then is also directed into the carburetor throat through an extended prime fuel passage disposed at a lower position in the extended prime fuel chamber than the point at which the prime fill passage connects to the extended prime fuel chamber.
