You shouldn't mess with the stitch width knob unless it's a last resort. They're old and crack easily. My 332 knob has been glued together in several areas( I didn't do it or break it) but shows the knobs have become a bit brittle with age. You shouldn't have to remove the knob, you just remove the plate from the back of the machine and clean it from behind. And I also applied the liquid wrench that way. Try going through the back of the machine. Let me know how that works:>
