I hope that someone here can help me with a problem with the magneto on my BSA A10 - 1953. I got at new fixing nut for the Auto Advance Unit, but I do not understand how to replace it. The old one will not come out, and disassembling the Auto Advance Unit means drilling out rivets, and I do not hope that will be necessary.
I am looking forward to hear your opinion.
