Your machine looks really nice, nice find. I agree with Mickey, frequent oiling for a while really helps get it cleaned out. Sometimes after oiling it will sew fine then gum up again, so oil again until it runs freely for quite a while. Someone said they put a brick on the foot peddle to keep it running and just let them run for an hour or two and sometimes longer if it needs it. So hope you find the answer and you get it going really soon.
