Are you sure your not confusing the screws that hold the bowls on with the drain screw?

I am confusing them

I stock both the float bowl screws and the diaphragm cover screw in S/S. Send me a PM. Let me know what year your carbs are and I can provide them for you.

I opened up my carbs and I found out that one is missing the vaccum o-ring... What kind of problems could this cause?..
