  1. I'm old as mud too, and I think the choke should get its power source from the alternator, so that it only gets a current when the engine is running, but hey, switched power would work too, I guess - just a different way of doing it...

  2.  @39junker  yep, these old engines don’t care about numbers, tuning by ear was the norm back in the day

  3.  @TEDodd  ideally it would get power only when the engine is running, but the OEM ones that run off the alternator are only 7 volts from memory. Aftermarket ones are usually 12 volts so I guess you have to take it off switched power. Positive side of coil would be a nice easy place to tap into

  4.  @loisrinehart6755  yep, set timing by driving, keep advancing until it pings under load then retard slightly. Especially with a cammed engine
