Snyders have the ball type originally called the Grose jet, they still suffer from sticking closed as they did in the 70s when we used them on SU carburetors to counter the flooding problems, ended up removing them.

The only problem I know of with the Viton tip valve is they sometimes need to be taken apart to remove small particles of brass from the machining process , this was discovered by Tom Endy.

I have a B carb , the only option is the ball valve, I would like to find a conventional needle and seat, which no one supplies, I would settle for a used part, if anyone has one?.
