Well, it is pulling straight, just not hardly moving at all, the stitches are so tiny (becuase the fabric isn't moving), that there would be no way to tear them out if needed. It is as though the feed dogs are DOWN - but they are not, and they do stick up, just seems like not enough to really grab.
I did oil it, as well as clean it. I will take off the face plate tonight, see if that helps.
