ABSTRACT:
A wet priming mechanism for small internal combustion engines. A priming line connects the main fuel line leading to the engine and the intake port to the cylinder. A manual bulb-type priming pump is located in the priming line and through operation of the pump, fuel is drawn from the main line and is discharged directly to the cylinder. Located at the discharge end of the priming line is a restrictor assembly which defines a small unobstructed orifice. The orifice is sized so that air will be freely discharged from the priming line by operation of the pump without resistance, but provides a substantial resistance to the flow of fuel. Through operation of the priming bulb, a measured amount of fuel can be injected into the engine to aid in starting.
