ABSTRACT:
A priming system for the carburetor-fuel pump of an internal combustion engine. The priming system includes a manually actuatable primer that is connected to the fuel chamber of the fuel pump, and priming fuel flows through a primer check valve either directly to an orifice in the carburetor throat or through the metering chamber, which communicates with the carburetor throat through main and idle orifices. In one embodiment, successive actuations of the primer bulb functions to purge the fuel pump, primer and priming lines of air and fill them with liquid fuel so that continued pumping injects priming fuel into the carburetor throat. In an alternative embodiment, the fuel pump, primer and priming lines are similarly charged but the metering chamber is also charged with fuel and the excess fuel is pumped therethrough and into the carburetor throat through the main and idle orifices. The metering chamber is left with an excess charge of fuel that results in richer operation during cranking and initial engine operation.
