Yes, If I loosened the screws that attach the rod to the bottom bar and I can twist the horizontal bar that connects the rod to the feed dogs and it moves as it should. The rod on the right is not rotating like the one on the left. That’s why I’m thinking it’s some connection, or possibly a bushing on the main shaft. If I tighten the screw at the top of the rod to the shaft, it binds up and the shaft doesn’t move.
I never could get the stitch length numbers on the dial to line up right, it seemed like that rod needed to go in more.
