Do you have a good spark (at a spare plug) when cranking with the starter? If so you may have a leak on the inlet somewhere. Do the plugs get wetted when choked? If so are you still getting a spark at the right place under these conditionsRegards, RAB

Is the starting by-pass circuit intact and working. It routes 12V via a starter mounted switch straight to the coil only when cranking. Won't start very well if dropping voltage through the ballast during starting when sytem voltage is already dragged down by the starter.
