The old 200B's are starting to show some issues. I am starting to see them come into my shop more and more lately. They start screaming during the cast. I have found that at the plastic base of the metal pins that the brake collars ride on is developing cracks. This lets the entire pin move out and drag on the friction ring making a loud squeal during the cast. The only way to fix this is to buy a new spool. This doesn't cause the backlashes you are referring to, it is just something to keep an eye out for. Actually, a couple of drops of oil on the friction ring will actually make the braking system perform better. Just a couple of drops of oil and spread it around with your finger or a q-tip. Also add a drop to the metal pin that the collar rides on. Lastly, put one or two drops on each spool bearing. This will make the system perform as it is supposed to. As far as the backlashing problem you are having, try taking the tension cap off and flipping the small copper spacer that is inside the cap. These spacers will get dented in and cause them to affect the spool tension. Good luck!
