Well, ran new wires and switched the reversing jumper... still no joy. No matter what, if it's in the magneto circuit, engine won't start. I sent an email to the manufacturer to see if they have any suggestions. On a side note, while testing this today I also had time to test the smoke system in the same airplane and it seems to work very well. Won't know 'till I fly it but I think I'm going to like it! [8D]
Engine also ran flawlessly throughout.
