I want to thanks everyone for the suggestions. Am slowly working through them.
Got some pix, and did a little work today, but it's pouring, so the drive will wait a little...
Again - the carb is a Braswell (modified Holley) double pumper, 4 corner idle.
It looks like a "31" shooter.
Accelerator pump screw is in the "2" position... But I am not seeing the typical Holley Cam in there.
I put a couple of more pix below.
Tightened (slightly) the 4 base bolts.
Only vacuum lines I have are to the PCV Valve and to the Brake booster. No vacuum advance to the distributor. EGR port (or whatever) on the carb baseplate has a good seal - now has a clamp.
Timing is set correctly (16* at idle, with "all in" at ~2800).
