Hey everybody, I'm new here and don't know anything about quilting (i was looking into it the past few weeks) but i came here after a search on google for my newley bought Singer 431G Slant o matic. The seller told me it was cleaned and tuned (sorry i'm Dutch and can't find a better word) But it is NOT!!! It is dirty i do think he oiled her but way to much if i turn it on and sew with it there is a weard smell comming out of it. I really hope the motor isn't broken. So can anybody tell me where to start with the whole cleaning and tuning proces? I can't find much about this model online (or i'm looking in the wrong places). I hope you people can help me, i really would love to get it to sew again.
