Reply To: Petter A1 backfiring through exhaust.

Hi Charlie thanks for your reply that’s really helpful. Reading through it definitely looks like the timing is out so I will pop the magneto off and have a go at resetting it. There is a click which seems to occur at the time the points open and there is also a tdc marking on the flywheel so fingers crossed it will start.
Thanks for your help and advice
Best wishes William.
