Coughing, backfiring ... *UPDATE*

Last night after new wires and some tweaking I got it running, albeit pretty rough. I put a timing light on it, and reset the timing. I timed to 19 initial and around 32+or- total. It cut out, and I couldn't get it back. I put a new dist cap on, and tried to start it. It will only run while I'm on the starter. I let off, and it shuts off. It will fire with the starter engaged but then shuts off. I'm going crazy trying to get this thing running. HELP!
