When I get a thread jam like this, I use a tiny screwdriver such as those used for replacing screws in glasses that I keep in my machine case, and also a small plastic medicine measuring cup to put the screw in. DON'T lose the tiny gib screw. I also put a white or light colored towel under my machine so I can see the screw if I drop it. When you take the screw out and pull the arm back work gently so you don't break the arm. Sometimes it can be a "bugger" to get it all lined backup just right but take you time and you can do it. Be sure the little hook/finger lines up in the throat plate area when you are through or it won't turn. Go to the site the featherweight factory that was posted on page 2 of this thread and follow the directions there. You might want to print out those 7 pages to follow and keep for future reference those are great pictures showing you exactly what to do.
