Quote:If you use a dwell angle meter [prefered] then set the points to 49 degrees. As the rubbing block on the cam wears, the dwell will move through the range towards 55 degrees & your timing will slowly retard a little.
If you start at 55 degrees, you are already at the wrong end of the scale & it will quickly go out of spec.

I reset mine last night & it came out at 48 degrees. Close enough,....... but always recheck the timing whenever you adjust or replace the points.
