Oops, forgot something. With the pedal down and over, step on it and see if it goes down far enough to have made enough difference to have worked if it had been that far down in the "over" position in the first place. If so, shim under the felt to add some "down" to the "over", adjust it accordingly with the turnbuckle, and leave the rest of it alone. OK, I'm done now. That's everything I know about muffler rails.
