Hi Guys, I have an acquaintance who owns a 1980's MW machine. I don't know yet what model but she is having a problem with it. It could be that it is threaded wrong but I will have a hard time checking that since she does not have a manual. So my question is can anyone tell me how these machines are typically threaded and how the needle is placed (is there a flat side and which way does it face; does the needle thread from front to back, right to left, or left to right?) Have not seen the machine yet so all of this may be obvious but thought I would ask first anyway. Thanks for any help.
