Dripping carbs:
Did you ever measure the actual fuel pressure with the engine running by Tee-ing in a pressure gauge to the supply side of the carburetors?
The number I've always heard for Weber IDF's was 3 psi max, but Anthony tells me 2.5 psi is better.
Mitch, I service a local sand rail, just recently repaired the brakes on it. Several years ago(6 or 7?) I put dual 35 Solexes on it for him. Mechanical pump was putting out about 7 pounds! After adding 8(yes, 8) gaskets to the pump I got it down to 1.5 pounds.
But the point is, I measured it with a vacuum/pressure gauge. Auto Zone or whatever no-name store has them. I have two, a new one and my Dad's ancient one, and they concur.
My self-regulating Carter pump at 3 lbs.? It actually outputs 3.5 engine off, about 3.25 running. So when I say I KNOW my fuel pressure, I do.
I'm not just setting a regulator to "3" or taking the manufacturer's word. Cause they lie.
Ed: I'll never wear a helmet unless I'm on track and it's currently SA-rated, but yours looks nice!
