Hi WhaleMstr, here are my 2 cent's worth of nogoodadvice...

I tried opening the needle valves( idle mixture screws?) up a turn each - no go - tried 1.5 turns - no go - guess I should try 2+ next
Some of these carbs have 'reverse' metering plates, so the needles control only the air for the idle mixture; i.e. turning them outwards actually leans out the mixture instead of enrichening it.I cannot see if you have used this spesific carb size before, but it is a big carb, and giving the power valves a faulty vacuum signal will play havoc on the setup, I don't know this carb in detail, but can you possibly check the power valve circuit for leaks?
Do you have a vacuum gauge to see where your power valves open (or not)?
These kind of troubles can be hell to diagnose, good luck.
Olaf.
