Cutting out the bug screen won't do anything to the magnetic field unless you pull apart the entire motor assembly to get the screen out.
In one of your previous posts, you noted your 808-8A's had a weak pull on a screw driver compared to a Dayton driver. The 808's have a center Alnico ring inside a pot structure. This is very well shielded - it doesn't have a lot of stray flux outside the structure, thus weak pull for a screwdriver. The Dayton driver has a ceramic ring magnet on the outside of the magnetic system. This has tons of stray flux and thus has exerts a high force on a screwdriver held near it. In other words, that observation is completely as expected. I guess a bit late now as you already had them remagged.
