Have you not had it running since you built it up with the new parts you got?
If I remember right you fitted an HRC ignition box, it wouldn`t run, then wouldn`t run when you put it back to standard?
Sorry if I`m stating the obvious but these need the battery to run the ignition system. Not the usual magneto type ignition.
Sorry!!!! just read your post on the MC18 thread. Always putting my foot in it.
Have you sent Andy a donation & asked him if he wouldn`t mind letting you have a look at the HRC wiring loom diagram?
