Ric, I'll give you a call Friday when I'm available next.
I assume you've checked timing on this as well? Pinging, if it is happening, would point to timing being too far advanced. Also, the Carb would need to have the spark control vacuum source. All stuff to check while you're at it.
The Holley 1 barrel is notorious for having issues due to warping. Actually, most 60 y.o. carburetors are pretty tweaked by now. I've been able to work past some of these issues before, but some I've seen are a too far gone. In these cases you'll need to be prepared for plan "b".
Will touch base tomorrow.
Roger
