Geary,
The screws have a slot on the threaded end. The two 'ears' are spread a
bit to lock the screw in place. You should be able to bring the ears
back together and loosen the screws to adjust the throttle plate. If
you've got a couple of weeks, you might order some extra screws in case
one of the ears starts to break off.
Cheers,
Bob Haskell
