A set of 8 throttle shaft screws and 10 bowl top screws for the Carter AFB carburetor. Be sure to use some lock tight on the screws when installing so that they don't end up in the engine. When removing your old screws, use a dremmel tool to  grind off the end of the screw. They are usually peened over so that they don't fall out.   Take your time removing the old screw. They break very easily.  Use a sharp 1/8" drill bit to drill out any broken screws. I can usually get all of the screw out with the  threads intact.
