Here's a little secret I just found out, if you have a drill press. Make sure carb is level and flat, a drill press vise works excellent, chuck up a 1/8 in drive high quality bit into drill. While using the pressure of the drill press as you are pulling the handle down, grab the chuck in the other hand and back out the screw. With pressure from the drill press it's near impossible for the bit to slip. I also have taken a file to my bit to make the sides more square to the surface. Most bits are tapered which allows them to climb and slip, if you file the bit flat at the edges it will bite the slot much better. When I discovered this I dug out some old carbs which I had given up on and tried it. They came out using this method. Remember these carbs are aluminum and too much pressure may strip the threadsif not allowed to back out..
