If you can wiggle the edge of the mag plate up and down much it means the aluminum boss on the motor or the brass bushing in the mag plate are worn. This allows sideways motion of the plate which affects the points gap which in turn affects the ignition timing.

To fix this, I remove the brass retaining ring and using a sharp center punch, I lightly punch the aluminum boss in six or eight evenly spaced vertical lines around it. This expands the aluminum enough to eliminate the slop. If the mag plate is too tight after doing this, the dimples can be lightly filed down for clearance. It’s kind of a band-aid fix but it does work.
