However, even then, the No. 7 is clearly not contributing to the engine ... never causing a drop in RPM when the wire is pulled. At 45 mph, the gauge is steady at 15 or 16 inches, depending on the wind and any incline.

You're vacuum low...should be around 20 and be steady unless you're moving the throttle.
