[QUOTE="HRD888, post: 36184, member: 79"] [b]Bth Magneto[/b] I have had a BTH magneto on my 1948 "B" for ~22k miles. I had two issues one was a coil that failed because probably because I bent one of terminals on the coil . I replaced it which fixed the issue. The one other issues I had was with the BTH spark plug wire. Which has a carbon core. I had miss firing and the engine would run on only one cylinder or was intermittent. Took me a few days to diagnose the issue. What I found was part the carbon core in the BTH plug wire had vaporized and created a open ~1/2 of a inch.
