    quote crosbyman:

    high vacum (by supplying a ground by contact closure) kills the bottom plug MOMENTARILY IF in neutral and RPM exceeds 2000 rpm or more

    That confirms what I thought!…

    …which is why I asked: "what’s the point"? If I were to have a high-rev situation, first thing I’m going to do is yank back the throttle. (Isn’t that the normal first reaction?) Doing so defeats this safety circuit altogether, right?

    Provided the person at the helm has the wherewithal to reduce RPMs in the event of a problem, doesn’t this circuit constitute "an ingenious solution to a non-existent problem"?

    As I rebuild (and rewire) this engine from the ground up, is there some reason that this circuit really ought to be reconnected? I’m not seeing the need, but I’m completely open to meaningful input as to why it’s as essential as some say. Like I said, I’m told it’s a "must have", but nobody can explain why…
