I stuck a pin through the temp switch lead and grounded it and the horn didn’t operate. Am pretty sure I tested the horn when I put the box together. Something else to track down.

Other question: I notice that the two timing “grids” show about a 1-2 degree difference in timing both at 5 deg and 28 deg. I think it is the same point set that breaks, so it would not be due to a difference in the setting of the two sets. Is that right? I’ve checked the idle timing both statically and with a timing light. (The book calls for checking the advanced timing at 4500 rpm and I’m not about to try that on muffs.)
