@ Tuner, everything is apart right now.
Carb is made, set up, it was symmetrical front & rear.
When trying to get it idling only the primary side was set to increase idle;
the way we used to do it with the non-ultra XP carbs. Live and learn.
No, I have not replaced inlet o-rings. They are original. That is on the list of things to do.
I do have two tuning kits, I'll attach pics of them.
The new Holley tuning guide, (-1) says to set the primary and secondary the same amount
when adjusting the idle (after setting the the center flow through).

My carb part number is 80805-1.
Current part number is 80805HBX.
I don't know what the difference is.
When I pulled the carb and removed the throttle plate,
I noticed throttle blades had about 1/8 inch clearance between them
and the bore. I if I recall, the t-slot was fully exposed--Yes, I know,
I didn't think to check them.
When I reassemble the throttle plate, etc, I will measure them.
and post the results.
I did find a site that showed how to set up the primary and secondary
pump squinter linkage, but I can't find it any longer. I do recall it showed
using a feeler gauge to set the clearance for primary and secondary linkage.
This was shown on the carb, not the acceleration cable.
Next steps, finish cleaning, find parts from kits, then begin reassembling.
At this point in the process I won't make any additional changes to carb
until I get it up and running on Chevelle (spell check want chenille, go figure).
If I'm missing anything please advise.
Please note I intend to do this in a process, Starting with the Holley carb at baseline.
From there, I'll make one change at a time, then documenting it.
I've done this process once before with my old BBC. Before I pulled it, the guy I had install the
new BBC told me it was the best BBC that he has ever ridden in, and why would I want to change it.
My response was that I wanted more of everything. Then we pulled and replaced it with the new improved
BBC that TW/DV sold me. It had to be towed from the installation shop. The engine has never run correctly.
With that, If I haven't said so, I appreciate everyone's thoughts and advise to help me get this
engine up and running in my Chevelle. I need to drive it again, and enjoy it while I can.
It will be a gift to my little girl when I've passed--She loves this vehicle.
Final thoughts:
The process needs to be as controlled at I can make it. Gong back to baseline,
and starting from there.
Keeping my assistant busy and out of trouble.
