So glad to hear you fixed you problem
@Wayfarer , I will be having a look at that video.
I have a Singer 611g which I use a lot, and since I had it, it has this problem. I've put off trying to fix it, as it is in a Horn cabinet, and that makes for a more complicated fix. Very strangely though, a week or so ago, the problem seemed to resolve itself, and it is sewing beautifully!
Just in case though, I've bookmarked that video!
