Thanks Sewnoma! I have the manual. It came with the manual, cams and a few extra feet. It's possible it's user error. I really need to sit down with it and the manual and make sure the settings are correct. I don't think anyone has done anything inside it except me. It's too clean. I don't think it saw any oil since it left the factory.
The hook assembly on mine is really finicky, it popped out of place inside the race a couple times on me now. Have you noticed anything like that with yours?
The only thing I don't like about the machine is Sears used the ugliest shade of green possible on their cases during that time. The machine itself looks great.
