I just bought this recently, it’s been sewing fine but had trouble with zig zags so I was trying to fix it but now it won’t even do line stitches. With zig zags, it wouldn’t do zig zag stitching sometimes and would just make straight line stitches so I thought it was a timing issue. But now, it won’t even make a stitch/make a knot with the bobbin thread even thought the eyelet is where the hook is at.
Do you guys know what the issue and how to fix? 🙏🙏
