Rick-
I never made it to full throttle. It would drop to about 3.5 when I would put the throttle about half way down- rpm was around 2800 or 3000. If I rolled on the throttle, it would pull hard, but if I stepped on it, it would hesitate/miss for a while and eventually smooth out and pull hard. This was the same with the standard spring in the secondary or the small yellow spring.
I'm haven't measured the vacuum at the port on the metering block. I'll have to check that tonight.
Incidently, I had the same problem with the hesitation/miss with the 72 jets as I do with the 70s. The only difference is my eyes aren't buring as much with the 70s
