Reply To: Petter A1 backfiring through exhaust.

[disco2]

Hi it’s Will I thought I would share my happiness I have got the Petter running and it’s running perfectly 😁 it was as simple as the ignition timing was 180 degrees out so took of the mag and rotated the flywheel half a turn and re fitted the mag and it started up. One word of advice though make sure when ‘re fitting the mag that the little clip that holds the points cover on is not trapped between the mag and the valve chest because you have to take the mag off again to free the clip. I found out the hard way.
Thanks for your help and advice
Best wishes William
