Hello ... I asked the original question. I have done the following to try and solve my problem: Turned the thread spool upside down, replaced all pigtails and added two additional pigtails, put batting on the loop above the thread spool, used a thread net, bought a new bobbin case, bought a new hook assembly (which meant I needed to re-time the machine after installation), bought a new tension controller, loosened the sandwich, changed the needle more often, changed the way I threaded the machine through the second three hole guide, sanded the hole in the base plate, checked for threads in the wrong places, and probably a dozen other things.
What I think I will try next is to stand on my head, click my heals together and hope that helps. HA HA. I must admit, I have had less loops. Which of the things helped?...who knows. What I do know is that I have had such wonderful support from this forum. All that responded had really good suggestions about what to try and I tried all of them and then some.
So, I will continue to watch my tensions, keep things lint free and change the needle more often.
Thank you...all of you...for your support.
