I suspect your discs might need to be cleaned. Perhaps you were using a thread with a lot of fluff, and the fluff is now embedded in the discs??
King Tut is a great thread, and IMO not too "thick" to get through the tension discs.
Mine's a Janome 4800. I've just had it serviced to check the tension discs, but this problem continues. Similarly, my "new" 201 had been thoroughly cleaned and serviced. I'm relieved to hear that the 6600 is OK with King Tut, as I'm hoping that one happy day, if I ever find the money, I'll have one of those!
