Thanks for the advice Joe and Misskira. I just spent a couple of hours taking everything apart and putting it back together. No threads caught anywhere. Took the faceplate off and the timing mark seems to be right where it should be. But the needle thread still winds around the bobbin race and gets caught everytime I try to sew. So I guess I'll make a trip to my repairman tomorrow. Never had this problem with any other machine in over 40 years of sewing so I don't have a clue.
