Carb part ID assistance...

[Bonz]

Hey guys, can anyone ID the black o-ring in this kit? Link below.

Is this for the pilot jet, looks too big for under the airscrew...

My wife's uncle is doing the carbs on his 83 XJ750 (Seca) and some kits have this part, some don't. Want to guide him in the best way to go.

Thanks!

O rings I can think of include the TINY one under the air mixture screw, the one around the needle seat, the one on the drain bolt. Pic is really poor, but it could be the drain bolt one - that is about 3mm dia or so.

Ahhhhh... for the float bowl drain screw...

Any other takers, or is JW gonna be the winner?
