Most of the throttle shaft screws at that time were peened over on the end so they would not back out rather than be locktighted. If that one is peened, trying to remove it may have pulled the distorted threads up into the shaft threads and galled to the point the screw and shaft are one. If it is only a thread or two holding then drilling out from the broken side may provide enough force to break it free and let the remainder unthread.
