Jerry - have to disagree. Blue Loctite, not red!
For future reference:
Like Jerry said, the back side of the throttle plate and choke plate screws are "staked" to prevent them from backing out and being swallowed by the engine.
To remove the screw, grind off the staking BEFORE using the screwdriver.
IF you twist one off, DO NOT TRY TO DRILL IT OUT AND USE A NOT-SO-EASY-OUT!
Instead, grind off the head, and just start a hole from the head side. Now heat the throttle shaft and screw to not quite the melting point, and let it cool. Now put a very DULL bit a few thousands larger than the one you used for the starter hole in a variable speed drill, and attempt to jam the bit into the screw. Once the bit catches, the drill will spin the broken screw out in the normal direction of the screw.
