Try it with the clutch out and see how she spins. I have noticed that they do need a shot of oil every once in a while. There is a circle under the bobbin - stick a drop in there and see how she does. There was one machine I got that had a real drag to it. I oiled it up real good. The motor would spin like nobody's business with no load. So I thought well maybe it is just weak or something so I traded a good motor into it. Well that one did the same so I knew it was somewhere in the machine. I oiled and re-oiled. Still had a pretty good drag. Finally I turned that thing on it's side and oiled the bobbin area real good and ran the machine - all of a sudden that thing wanted to run. I'm guessing the bobbin area. You might give the rest of it a couple drops - I'm just a woman so how would I know...
