Abstract
A fuel primer for small internal combustion engines is disclosed. The fuel primer is associated with a metering chamber of a carburetor. The metering chamber includes an inlet port and an outlet port and communicates with both a fuel source and a venturi on the carburetor by conventional means. The primer includes a mechanism which communicates with the restricted inlet port to provide one way flow into the metering chamber. A second mechanism communicates with the unrestricted outlet port to provide one way flow from the metering chamber. A third mechanism associates the first and second one way mechanisms for pressurizing and depressurizing the flow through the primer so that fuel is drawn into the metering chamber from the fuel source.
