pull plugs and clean them. after all this they may be fouled. hate to think this was a dirty set of plugs and an originally flooded motor,hold your finger over each plug hole while someone turns it over and check for compression on each cylinder may be a rocker shaft loosened up. but at any rate gas and spark are no good without compression. make sure connections at starter relay are tight also. i think it is the brown one that can keep it from running. If you can find a 20. ohm meter check continuity on the wires in the primary circuit for resistance. a cracked wire can cause a problem like this especially the wire that runs to the points. if one has a lot of resistance jumper around it. hope this helps. wish ya were in houston. i could use a wrenching bud.
