Previous owner replaced (Cat 4B389) magneto using 16T drive gear (Cat 2A4144 that) has tapered input fitted to original magnetic rotor using woodruff key. The Wico replacement mag (Cat 4S6471) has magnetic rotor with “D” shaft instead of original tapered shaft. My adapter bushing is worn causing excessive rotational play, 8 to 12 degrees. Is anyone able to give advice on how to remedy this issue?
