Re: Rough Running
This is most likely two things...
First, is that your timing is off. Make sure you hook up a good timing light and time it correctly to spec. If you don't have a light, try retarding the timing a little to see if this helps (retarding it is clockwise on the distributor, and you don't have to do it much, just a little bit to see if it's improving or not)
Second would be that you're flooding the engine, making it harder to turn over once it does flood. After it sputters and dies, get a light and look down into the top of the carb. Try to see if it is unusually wet with gas in there. If it's flooded, you've probably got a float problem.
The vac line to the tranny wouldn't cause it to not turn over very well. When I put my new carb on, I accidentally left that unplugged, and it started fine, it just wouldn't hardly move down the road without the vacuum.
I'm going to guess it's a timing problem though.
