Abstract
A float bowl type carburetor has a fuel and air mixing passage extending therethrough, a float bowl assembly, a priming pump communicated with the float bowl assembly and a fuel supply pipe that is communicates fuel in the float bowl assembly with the fuel and air mixing passage. The priming pump is operable to deliver pressurized fluid into the float bowl assembly in the area of the fuel supply pipe. Preferably, the priming pump discharges fluid in line with the fuel supply pipe so that at least some of the fluid discharged from the priming pump flows directly into the fuel supply pipe to facilitate delivering a rich fuel and air mixture to the engine to facilitate starting the engine.
