ABSTRACT:
A conventional carburetor has a manually compressible bulb associated therewith which displaces air into a priming fuel well thereby forcing a priming charge of fuel into the carburetor throat. The bulb, which is formed of rubber-like material, has a central dome portion joined to an annular flange. A surface of the carburetor body has a cavity formed therein defined by a side wall and a bottom wall, the bottom wall having an annular shoulder defining an annular groove with the side wall. The bulb is positioned in the cavity with the annular flange seated in the annular groove, the dome portion thereby defining an annular slot with the side wall. An annular, spring metal sealing ring is positioned in the annular slot engaging the annular flange of the bulb, the sealing member having spaced projections thereon which frictionally engage the side wall thereby retaining the annular flange in sealing engagement with the annular groove.
