I'm fussy, and don't like to drill out the carburetor control arm on a nice engine just to install a 2-56 screw. So I found some leader swages (just tiny copper tubes plated with silver nickel) at the fishing store that are just the right size for making a bushing in the ball, that will accept a 0-80 machine screw. You need to take a screw and ball with you when you go to the fishing tackle store, to make sure you got the right size. They're too long (~1/2"), so just chuck one gingerly in your drill, and use a sharp x-acto knife to cut to length. Go a bit long and use a point file or emery board to get it just the right length. I like to make them just a bit long so that they compress when the screw is tightened. I use the socket head 0-80 screws.
For #1 screws, you're on your own!
