Hi again, Dwell is the period of time, measured in degrees of rotation of that distributor shaft, in which the points are closed, thus allowing the field windings in the coil to charge to a sufficient amount to give a good spark at the next collapse cycle. In other words, it is a "fine-tuning" of the points and is measured with a meter called a dwell meter. The specs are usually given in the tune-up charts and are usually given in a range such as: 27 to 32 degrees, for example. Remember the little metal “window” on the GM distributor caps back in the days of their engines using points? This was to allow the points to be set with the engine running using a dwell meter and an allen-wrench. Downside: At the time that our old tractors were born, analogue and digital dwell meters were mostly unheard of; and most of the specs were just given in “thousandths of an inch” gap measurements. However, given a good distributor with a good set of bushings, these “gap” measurements will correlate very close with proper dwell angles. The point I was trying to make was that the final point setting does indeed affect engine timing; and more aggressively than what a guy would guess. This is why it is important to set the points first prior to adjusting the engine timing, because doing it the other way around, allows the process of setting the points to again change that engine timing. Hope I’m making sense here. Later, Allan
