Pulled the Mess that was my Timing Chain....

Ended up getting a new carburetor, rebuilt but never used. Hooked it on, got all reconnected, went to start it and....SAME PROBLEM! Rough running, barely can keep it running (maybe it's a hair better now), misfiring or flooding. Shaking the entire car with how rough it runs. No backfire, and seems to want to start right up. I don't get it. Am I off a tooth in timing? I am trying to fire it off at TDC, and it really shouldn't run this horribly....
