All other screws came lose easily--but this one is now rounded and won't come out:

Easy-out, the worlds most inaccurately named tool.

This is for future reference, but using a High quality screwdriver will help prevent you from repeating this in the future. And the knowledge that torque (force) is cumulative, meaning that if you put turning pressure on a fastener and just HOLD that pressure, the force builds up and the fastener will eventually let loose... without buggering up the fastener. VERY handy on the screws that are used on the brake (and clutch) reservoirs on motorcycles. Ditto on the Phillips that holds on the bar ends on most motorcycles.

So, a few options... use an impact tool (the kind you hit with a hammer). Threads may be too far gone for this. Use a drill bit (reverse bit is best, but normal will work) ~ the reverse bit may grab and unscrew for you otherwise just pick one that's the same size as the shaft of the screw and remove the head. You can disassemble the carb and probably just unscrew the remaining bit by fingertip (it's the force caused by the metal stretching that's got it so tight). Worst case, you use a vice-grip (the remaining threads will be sticking up enough to grab). You can also cut or grind the head off, or try cutting a flat slot in the top with a dremmel tool (or similar).

This is a Very common thing when working on motorcycle carbs ~ I've had to do the above hundreds, if not thousands, of times over the years. To skip the headache with This set of carbs in the future, replace all the OEM Phillips head screws with sock-head (allen) screws. You can find replacements locally.. ACE Hardware stores tend to have the best selection of metric fasteners though some Lowes/HomeDepots occasionally have something that'll work. Just take one of the other screws with you to aid in finding a match.

Looks like you could get in there with a little cutting wheel and ream a notch out into a flat-head slot, and take it out with a wide flat head screwdriver. If it stripped that easy, it's probably not too hard to cut a straight notch across it.

I was going to suggest the same. Cut a slot. I also use a hand impact driver. One of the first tools I bought when I started riding years ago. Expecially if you work on older bikes. Or just over tightened screws or bolts. Most times, a hand impact driver will get it out without cutting a notch.

My friend managed to get it out with just very small pliers. Took him 3 minutes. Thanks for everyone's advice. I'm sure it will come in handy with a more difficult to remove stripped screws.

Remember to use the silver anti sieze on before replacing ANY motorcycle fasteners. You will thank yourself later.
