I realized that when I lock the dec clutch the saddle moves with the large worm wheel. When the clutch is loosened the worm wheel and the saddle plate move independent of each other. Well uh......the entire assembly can be rotated in Dec regardless of the clutch being tight or not perhaps because the small worm block has been removed from the dec assembly? I took it off first to clean it but didn't realize that it may appear that the clutch works with it ??
