I'd look online at someone like Yamaha of Troy that has a schematic of your carb and see what matches. They show just about everything on the carb.

If you haven't already figured out the mystery screw, go to www.sudco.com
click on carburetor diagrams
Could your mystery screw be #18? "Stop Screw" - goes inside a hex nut into the throttle shaft and adjusts the closing limit of the slide. I recently took apart my '99 wr carb and seem to remember this screw fitting your description.
