Abstract: A carburetor priming system for an internal combustion engine includes a porous wick disposed in the inlet of the carburetor and a system for initially saturating the wick with liquid fuel prior to starting the engine. The priming system which may be remotely located or adjacent to the engine, which saturates the wick, consists of a depressable flexible bulb which withdraws fuel from a fuel supply and, when depressed, forces the fuel from the interior of the bulb into the wick. A check valve between the bulb and the wick is mechanically actuated to open when the bulb is depressed rather than being opened by fluid pressure as in conventional systems.
