Thread breaking & skipped stitches
I’ve been lurking on this board for a bit and I’m enjoying reading everyone’s posts. I need advice about an ongoing problem. I’m wondering if I should just have the machine serviced. I have a “new” (store display) Kenmore. I’ve been having problems with the secondary thread shredding while sewing with a twin needle. I think it’s something with the take-up lever on the bobbin–because now I’m also having problems with skipped stitches on the secondary thread as well. I loosened the upper tension to no avail. The skipping isn’t a problem when I go at slooow speeds. Anything else that I should be troubleshooting? Or should I just take the machine to the shop?
