Stumble with rebuilt Thermoquad /340

Guys thanks for all the input!!!!!!! .
I appreciate the car guys helping another car guy out. I need to do the advised homework and will let everyone know. Carb is going on the same 340 it left the factory with. Yes the choke is disconected.
If I get this carb sorted out I will pull the manifold and get the choke back hooked up.
