Coughing, backfiring ... *UPDATE*

Ok So I check timing, seems to be ok. No obviously bent rods or rocker issues on bank 1. I got it running again. It's not missing or coughing too bad. It is still idling rough and every once and a while backfiring. I am pretty sure it is because it is running so rich. It just reeks of fuel. It's not banging or knocking like something on the rotating assembly is broken. I replaced the plug wires just in case that was part of the problem. Any ideas on how to lean out a mighty demon?
