Dwell can be checked with the engine running or cranking. Decrease dwell by increasing the point gap or increase dwell by decreasing the gap. Dwell angle is simply the number of degrees of distributor shaft rotation during which the points stay closed. Theoretically, if the point gap is correct, the dwell should also be correct or nearly so.
