I am a little confused now and just remembered this at lunch while surfing. No way
have I ever seen the gap widen, yet.
All this advance/retard stuff is nice on paper, but figure this. I just thought back to last friday night. I had uncovered my points and tried to check the gap with a 14 thou guage. It wouldn't fit between any of the sets? The gap had narrowed on all equally more or less. Don T-nut put in brand new points in June, after a couple weeks the performance was gone and the gap had narrowed as well, 10 thou. I checked it at the time because I could see it was too narrow. I reset and timed it to 20 degrees, this evidence would lead me to believe the gap had gotten smaller. My cars that had points I think the same thing happened, altho it has been 20-25 years.
I am not trying to be a PR, I think that my findings show me the same thing Mr. Glenn found. The gap narrowed which in turn changes the timing, retard/advance doesn't matter right now. What matters is I see a defined difference to the narrow and not to the wide,
twice in a row. New points, the cam block will wear in fast and need a reset, then slow up as the nylon becomes super smooth and harder IMO
Ian Square Four, out of curiousity could you check the gap on yours and add to this post what you found. For the points to erode and burn off takes carelessness in gapping/dirt/or oil and/or bad connections, I have none of this present. Lack of lubrication on the cam will wear out the block quick and narrow the gap. Burned / pitted points would continue to get worse quickly and the gap would widen, you would think. My points still look like new after 2000 miles. Points do erode from normal use, but IMO not faster than the nylon block. I put 4000 miles on the 30 year old points the engine came with last summer. From what I remember there was ton's of tunston left.
