Thank you so much for the auto-threader info. I have a 770 qe plus, which does not have the automatic threader, but a manual one. After watching this video, I realized that my threader may also have fuzz in it as the last few times I used it, it took 3 or 4 times before it caught. Lo and behold, fuzz! Cleaned it out just like you showed, and it works great again. Thanks again for the helpful hint, not sure I would have thought of it on my own.
