Here it is 2019 and as an owner of a Kenquilt 622 I am reading your post! I have had my machine, purchased new in 1990, for many years and supported myself with it for 5 years so as you see it has been used, used and used. I have one question: If you push your thread take up lever down does the needle bar move? My machine sews like a charm but I don’t remember if it has always been this way. Oh, and one more thing...I am getting a bad smell and the motor is really hot to the touch...don’t remember that either...thinking I need a new one? I am having a bit of trouble remember things due to chemo brain. (I am a cancer survivor...happy days)
