Neil, Your advice was spot on. I adjusted the yoke inside the clutch housing to increase the tension on the input shaft brake. Hopefully I tightened it enough, but I didn't get a chance to try it yet. Thank you again for your help!

All, the rebuilt mag from Brillman's works great. I did have to swap wires, but it works well now. When I installed it, I cleaned the base extra good and applied the pencil carbon to the base of the mag. Thanks to all for the help! Elton
