I acquired a seiko stw-8b a while back and I got some time to try to get it working. Uwe's videos have been a fantastic help, as has this forum in general. I am having a great deal of trouble with the reverse mechanism of my machine. When I put it in reverse, sometimes it wants to pop right out of reverse, and when it does go in reverse the stitch length is much shorter than the distance in forward. There have been some other threads where other members had an issue with the reverse, but they just mentioned that they solved it and did not describe how. Or if they did, I did not understand how. I don't think I even know enough of what the machine should be doing when it switches from forward to reverse to know exactly what needs to be documented.
Thank you.
