Before I cleaned the sleeve I smoothed the little edges within the sleeve, and the angles are fine. Thank you, and all the others, for sharing such valuable information. I love tweaking these little motors, and after destroying many motors, I finally have an idea of what "to do" and "not to do." Now, where can I buy a sleeve pinching device, and are they worth it?
