Got the carbs off my GS this afternoon, start rebuilding them one at a time, turn them over to pull the float bowls and notice that the caps are gone from the pilot screws (This is what the Clymer calls them) and the Clymer shows caps being there so I figure this is cool, a Previous Owner pulled the caps so I don't have to. Only they completely screwed up one of the heads on one of the screws and I can't get a screw driver to turn the thing out.
What's the best way to get this thing out? The other one is fine and turns freely, this one I've barely budged after scraping at it with a flat screwdriver. I'm also curious what kind of idiot thinks unscrewing the pilot screws is enough to compensate for a full V&H exhaust; the main jet is still 122.5, no idea on the primary.
I'd say try a screw extractor. I don't know how they could have bunged up the head, but hopefully the threads are okay. Get a new screw and probably new o-rings for both.

My guess is a ham-fisted drill operator; it looks like they were using a small drill bit and ran through the cap and straight into the head of the screw, only not completely straight; there's a gouge running from the milddle of the head then off through the one of the lands on the head. Like half of the screw head was simply blown off.
I'm not sure how I'd get a screw extractor down into there, they're in a bore about 1/2 of an inch down and it's not very large. Maybe I need to google screw extractors and see what's available...
I have a set that I got from autozone, the 2 smallest of which will fit with no problem.
