I'm chiming in. That 60 holder is way too small. Remember that the holder is simply an idle air corrector. If you restrict the size, it minimizes the braking action on the fuel; therefore, you are going to run much richer with a smaller holder. I would try a 120. I have seen some some FE motors requiring 50 or 55mm idle jets., as well.
Aggie has worked hours on getting his system in shape. If you have some leakage in the throat, either the float level is too high (Aggie can give you my system on how to measure them) or you are leaking after the engine is shut off. The Weber needle/seats are prone to leak into the main bowl (often times the last carb in the circuit suffers for it). You can pick up some D & G Grosse Jets that will cure the problem (I have just a few sets left) and/or run a return line back to the tank.
Please let me know how the smaller holders work. This is always trial and error and I would be interested in the results.
The third progression hole does work very well but you need to know someone who can do it correctly. It is really a last resort if you have trouble with the transition that can't be cured. The 50 or 55 bypass should take care of that, however.
Aggie: A question for you. Tell me exactly what happened with the bypass valve that had zero return in the valve.
Good luck guys.
