Trade Street Demon 750 carb for 625 carb or other

I have a nice Edelbrock 600 electric choke.

Rusty, I'm glad you chimed in. I really want to use my stock TQ carb and only purchased this one in case the rebuild it needed did not go well. Unfortunately the TQ carb floods now after the rebuild. I made sure I replaced the "o" rings at the bottom of the fuel wells and replaced the floats with the brass style. Checked the float setting numerous times and is at 1" off of the gasket surface. The one thing that I did not like about the rebuild was the gaskets under the seats were really stuck on there and I used as small flat tip screw driver to scrape the gasket off. I may have damaged the surface where the gaskets sits. Do you think this gasket surface would provide enough leakage around the threads of the new seats to cause this flooding? I would be willing to trade this new carb for a good running TQ carb for a 4 speed 340 car. Thanks
