Do you have the bobbin in correctly? Some of my machines the thread comes off of the bobbin one way and some have the thread coming off the other way. It almost sounds like a little barb somewhere working until it breaks the thread. I would take the sewing foot off and check it for barbs and also the [well I can't think, must be my old age] the THING THE PRESSER FOOT SITS ON [I still can't call it up]. Sorry, I get carried away.ha. FEED DOGS! Check the feed dogs for a barb somewhere.
