I think your fuel pump has crapped out. Pull the fuel line off the carb, pull the coil wire out of the socket, have someone crank it over and watch the fuel pump into a big glass jar. THe jar should fill up rapidly if the pump is good.
Set your timing at 12 degrees when you get it running and then reset the dwell on the points in the distributor.
When you set your timing did you plug the vacuum advance to the distributor?
