I'm not confident enough to mess around with it beyond my two tries to reinstall it for better result. Any suggestions?
jljack,
It's a case off needing adjustment. Without having it in front of me to tinker with I really am not versed enough with them to tell you how to proceed. I do know that in my 201 manual and several others they go into great detail on how to remove, disassemble, reassemble and adjust the top tensioner.
So my suggestion would be to go to the Singer home page and download and print a manual if you don't have one.
Sorry I couldn't be of more help.
