so, after a few days of messing with my 20 plus year old analog dwell meters and trying to get the stupid meter zeroed out I decided to buy a new meter. did a search on the web and found the tool listed below.
not only does it provide clear led readouts for dewll, rpm etc, it also doubles as at multimeter if needed. my old one did not.
now I can set the dewll with real accuracy. set it today at 39.3 degrees.
