ABSTRACT:
The priming system for a dual feed internal combustion engine provides a lighter, starting fuel to the venturi, the fuel nozzle, or to the carburetor bowl for engine starting. In a first embodiment, the starting or secondary fuel is mixed with the primary fuel in the fuel bowl, and the pure secondary fuel is provided to the fuel nozzle by actuation of a manually-operable primer. In a second embodiment, the secondary fuel is mixed with the primary fuel in the carburetor fuel bowl, and a shot of pure secondary fuel is provided directly to the carburetor venturi by the actuation of a manually-operable primer. In a third embodiment, a primer is manually operated before engine starting to remove primary fuel from the carburetor bowl and return it to the primary fuel tank. Thereafter, pure secondary fuel is provided directly to the carburetor bowl for engine starting through a changeover valve. After the engine has started, the changeover valve is positioned to permit primary fuel to be gravity fed to the carburetor bowl.
