ABSTRACT:
A primer for an internal combustion engine carburetor including a variable volume air chamber which is provided with a flexible resilient dome member. The dome member includes a protruding nipple including an aperture therein for admitting air into the chamber. Inside the chamber, a protrusion is provided including a sloping surface with an aperture therein. A passage connects the aperture in the sloping surface to the fuel supply bowl. When an operator abruptly depresses the flexible resilient dome member, a volume of air is abruptly displaced from the chamber through the passage and into the fuel supply bowl to force fuel from the bowl through a nozzle and into a fuel/air mixture passageway of the carburetor.
