With your plugs jet black, it's getting way too much fuel. Does your fuel pump shut off with the key on (engine not running)? I should do a click or two and stop.
If it keeps going, the main needle and seat (the one the float moves) is leaking. And I would still have 2 fuel filters on it, back by the tank and one by the carb, both clear plastic. Are you sure you have the right plugs in it?
Mine had the wrong plugs in it when I bought the car.
I know your coil was mounted by the air cleaner when you got the car, so the next issue (to me) is a weak spark. When you put the new wires on, did you screw them into the coil? (you should, there are little screws in the holes in the coil that the wires screw onto). The plug wires, once screwed into the coil, cannot be pulled straight out. If you didn't screw them into position, there is a potential weak spark situation.
If the ignition points have become pitted, that can also be a source of weak spark.

Has Mike O'Connor confirmed he actually did some work on it? Dirty air filter wouldn't cause this. (try running it without the air filter. what happens then?)
Me and several other people have mentioned several diagnostic things you should do (several emails ago as well as currently). Have you tried any of them? If not, why are you wasting your time emailing rather than trying the various diagnostic ideas you have been give by several --experienced-- people? If you have actually taken time to try them, you would have found the problem by now. You have been given troubleshooting ideas on ignition, fuel, timing and vacuum.
None of the things we have suggested you check will take more than 5 minutes each.
Don't just post messages, get out and work on it.
If this seems harsh, then maybe I have made my point.
