This is just a word to the wise. When you install an ignition switch that does not "exactly" match the terminal positions in the wiring diagram, be sure to get the wires in the correct positions.
I changed my switch, and managed to swap GRD and IGN, no spark/no start!
Now it runs great. Luckily it only cost me $40 and a days work to figure out. It now has a new coil and condenser, runs better than before.
