I went wheelin' this past weekend and had my idle adjustment screw pop out on the trail (on my '85 22re). I did not have the spring that goes under the screw, it probably was lost on the trail somewhere, but luckily the screw itself found a nice home next to the screw housing *whew!*. So after looking at the dealer's parts diagram, I could not find a listing for the spring nor the o-ring that goes on the end of the idle adjustment screw. Anyone got a part number or something similar that I can use? I know that vacuum leaks have occured when this o-ring wears out, I want to replace it cuz it looks a bit worn...
