I use my Juki for machine quilting. Everytime I change thread I must adjust the thread tension. This
is causing a lot of lost time sometimes it takes hours before I can get the stitch corrected. By then, I don't want to quilt!! Does anyone know what is wrong?

Without seeing what the machine is doing it would just be wild guesses. It really shouldn't take more than a couple of minutes to adjust the tension when you change threads.

Be sure your pressure foot is up, the tension won't change at all if it is left down.
