When measuring the RPM of my '74 2.0. with conventional points, using a digital VOM I get twice the expected RPM values. Yes, I have the VOM set to 4-cylinder. I know what a 1,000 RPM idle sounds and feels like, so I am sure it is the VOM reading double. Analog meter says 1,000 yet the VOM says 2,000. What gives?
