We added more nylon washers to the seat back assembly to make it easier to adjust the seat back fore and aft. In the Sportsman the seat bottom does not move. Our older Sportsman seat design, required you to lift a pair of spring loaded pins and then push the seat back fore and aft. That was not easy as the back tended to jam on the square steel tubing. Later the Glasair factory updated the design so you could lift both pins with one hand and then coax the seat back to a new position.

To get the extra washers inside the square rail, required trimming them on two sides so they would slide in. This modification definitely helped moving the seat back. Later we will come up with a way to hold both seat back locking pins up, either providing a pin on which to hang them or some other way so all you have to do is move the back, not hold the pins up.
