The first thing would be to find a manual for it and read it. They really help a lot.
You guys look or I guess sound like. LOL knowing people when it comes to sewing. I just got a Morse 5201 from what I can see and I'm having trouble running it. I can figure out where the back stitch button is and I can get it to do a consistent straight stitch. I bought it from a Guy who fixes sewing machines so I can help think it should be fixed but here I am asking for help! Please help
