All this talk of timing and carburation, yet no conversation about point gap and spark?!!?!!!  Are the points new, or are they corroded?  The plug wires were changed but what about the distributor cap, rotor, and points?

Beermanpete's post, one before your's, #23. 

 If you still have points set the ignition timing using the "dead timing" method (after checking/setting the point gap).

Also, I don't see any confirmation in your posts that you have spark. Make sure you have spark at the plugs before going crazy with the timing and firing order. Perhaps there is a problem in the primary wiring.
