RE: A PUZZLING SITUATION FOR SURE
You must eliminate things and move to the next thing that could be the problem; you or any one having an issue cNT FIX THE PROBLEM BY assuming some thing is fine. Elictronics do funny things im not saying that they are the problem but they could be.
once you eliminate the components of your ignition system then the problem is in one of three places your ign your engine or your engine setup. 2 of those will be fixed by sending the engine to DA.
Good luck finding your issue hope you get it fixed and have many years of flying out of it like i have.
