I have a question about a Pfaff 130. I have one and it is hanging up inside. I have oiled it and oiled it and it just won't run smoothly all of the time. The sicking part is behind the stitch width knob and controls the amount of back and forth movement of the needle bar assembly. It is a square part sliding in a channel. It will do straight stitches and do zig zag too, but when you are doing zig zag and stop it seems to hang up on this part here sometimes when you start back up again.
If you give the handwheel a little encouragement it will go just fine. But I don't like that it is sticking. Any help or insight would be greatly appreciated. Thanks.
