Hi Erling, thanks for your advice... I fitted a CPS, and it made no difference, so bought 3 new triumph coils, and it sounds/feels much better,. I'm pretty sure it will be OK... Next is to sync carbs, also find a way of adjusting fuel/air screws whilst bike is running, I'd love to just get it running and idling as it should, then I can just RIDE it! Thanks again.. Top chap..
