ORING FOR JET HOLDER MONOBLOC - NEW DESIGN
O-ring seal for the jet holder on Amal Monoblac carburetors, new-design version.
This is an O-ring that seats around the jet holder on the Amal Monoblack carburetor's new-design jet holder assembly. It's a small sealing part, but it keeps fuel from seeping past the jet holder where it threads into the float chamber body.

The part number RKC/624 is the Amal designation, and the catalog notes it as the new-design version, which suggests there was an earlier jet holder O-ring superseded by this one. We don't have more detail on this one beyond that.
If you're rebuilding a Monoblac carb and it's leaking or weeping fuel around the jet block, this is a cheap thing to check and replace while you have the carb apart. Call the shop if you're not sure which jet holder design your carb uses before ordering.
