Response to vacuum gauge
I use a old vacuum gauge about 2 1/2" in diameter, had it for years. Turn in the screws until you see an RPM drop, then open up to smooth/best vacuum reading more or less, then another 1/8~1/4 turn to stabilize. If you try to nit pick it, you'll never get to drive it. It's not that critical. As soon as you pull away, the idle circuit become a footnote to transition and the mains.
