The magneto on my 27 Chummy, a BTH, produces a nice heathy spark on a test bench, it runs ok on short journeys too. After about 20 minutes it starts to misfire and then the engine stops. It then wont start again. I'm sure its the mag because swapping to a coil conversion unit cures the problem instantly. This last happened Wednesday last week. This morning Ive had a look at the offending mag and its sparking again on all four. I suspect the condensor, but my magneto exoerience is limited. Can anyone point me in the right direction?

Thanks
Alan Fairless
