THANK YOU, THANK YOU, THANK YOU!!! A couple of things...there was some lint buildup behind the tension spring in the bobbin case and it was out of time. After watching my Rick Taylor maintenance cd several times and a lot of pause, rewind,pause, rewind. I finally tackled the retiming of the machine...I was scared to death I would screw up something. BUT...(knock on wood)..I think I fixed the problem. Thank you all so much for your help..your the best.
