Bit confused about the spring on the bobbin case, do you have a plastic bobbin case know as Appollo ? there shouild only be one catch to hold the bobbin case in and that is on the right hand side, can you give me a bit more information, you said that you have tried several positions but the machine does not thread, can you expalain a bit more, e-mail me or post another question.
Thanks
Ken
