I’m confused as always. I would think that filing out the slot in the points base would make this problem worse….Less area for the offset screw to contact. But, I guess the offset screw can make contact with either side of the slot….Have you tried using the other side of the slot for contact. You may have to back the offset screw out a half turn or so if it bottoms out while trying to use the other side of the slot.
Sorry, wish I could draw a picture to better explain what I am describing here…
