Beschreibung
Zusammenfassung:	A primer for an internal combustion engine carburetor (10) including a variable volume air chamber (50) which is provided with a flexible resilient bulb member (51). The bulb member (51) includes a protruding nipple (55) including an aperture (56) therein for admitting air into the chamber (50). Inside the chamber (50) a protrusion (58) is provided including a sloping surface (60) with an aperture (62) therein. A passage (42) connects the aperture (62) in the sloping surface (60) to the fuel supply bowl (20). When an operator abruptly depresses the flexible resilient bulb member (51), a volume of air is abruptly displaced from the chamber (50) through the passage (42) and into the fuel supply bowl (20) to force fuel from the bowl (20) through a nozzle (40) and into a fuel/air mixture passageway (44) of the carburetor (10).
