Hi, new member here.For my job as an auto upholsterer I use a juki 563, I've always fiddled with little knowledge to try to improve things.Yesterday using a video from this site I set the stitch length indicator, the needle bar position and the feed dog.Stitching is much improved as quite often the thread was catching underneath (looked like the timing of needle to hook was out).However now as I'm sewing the reverse lever moves up and down, looking on here I see it can do it if the spring is loose but this is being physically moved by something.i ran out of time yesterday to look into it and was wondering if any of you knowledgeable people on here may have any idea what I should be looking for.
Many thanks, Keith.
Great site by the way.
