The machine was getting there. Now I had to address the weak tension in the pretension and the main tension. Carol Bryant, known as WyoCarol on some forums about this machine, was offering a fix she said was all that was needed to avoid broken threads. Her fix was to add larger tension discs from a donor machine to the pretension, as well as replacing the wimpy tension spring with the stronger one. This by itself did not fix my machine’s tension problems. It is a big help and remains part of the rebuild. Are you getting the gist ? There are a lot of people out there who own this machine and can’t use it. With no factory or dealer support it is every man for himself and self help.
Something I saw on nearly every other machine was a bar in the threading line as it comes off the main tension. I had to fashion something that would work. I took a quilting bar that goes on an even feed foot and bent one end into a loop. This allowed me to attach it with a screw. The thread now is totally away from the open space and can’t get caught around the flywheel.
Oh this is really going to work!

Right beside the quilt bar attachment, there is a hole. On my machine there is a pigtail thread guide that effectively does the same thing as your quilting bar attachment. Wonder if you were missing it?
The pigtail doesn’t do the same thing. It is too far away from the tension spring. That is why I fashioned the bar. The pigtail was put to good use at the top of the machine as a thread guide.
