Figured I'd post what's up, even though it ain't very flattering to me. I put the old coil on and it runs just fine, minus two-cycling every once in a while but that might be due to wanting new plugs. Most I can figure is that it was the diode. And that the place I got the coil from has the right and left backwards on the diagram - when facing the carb "R" is on the left side and "L" is on the right side is the correct way.
Thanks for the help and rattling the stones in my head about two different coils!
