Dwell Angle

[Jim/GA]

I agree there is no "spec", per se. I carefully set the gap on some new points with a feeler gauge. Then, when the engine is running, I measure the dwell, just to see what it was (for future reference).

I use that number to do a quick check for point "follower" wear. Every time I change the oil, I connect the dwell meter just to see where it's at. It is quick and easy to do. If the dwell has fallen too much from my initial reading, I open up the distributor and set the gap back out to spec with a feeler gauge.
