Got it working. I first used some gun cleaner on them to clean off the gunk, then oiled them good. The machine was surprisingly clean. It sews wonderful, I put elastic in a denim skirt this morning, no problem. Now I can let my Janome rest a while and piece my quilt tops on the little 404.
I now have 3 Singers, a 15-91 in a treadle cabinet, a 401a head, then this 404 in the cabinet. I have a 446 New Home in a three drawer cabinet. Then my HT2008 Janome that sits in a cabinet that had a Kenmore in it. I took the Kenmore out, didn't like how it sounds when I sew on it. Sounds like it is binding somewhere, also has some nylon gears in it. I have a Brother embroidery machine, 2 sergers, a Singer Quantum Lock 5 thread and a New Home 334, 4 thread. I also have 2 commercial machine, a Juki 227 and a Mitsubishi needle feed. Then the quilting Short arm Singer 1191 sitting on a 12 ft. table.
