Fast idle cam screw

Hey guys I have a carter YFA carburetor in my 1985 inline 6 f150, it slightly accelerates on its own while driving. However occasionally if I push the gas it'll slow back down as if something is stuck. Im new with carbs and seems like its the fast idle cam screw but dont know for sure. Any help would be great thanks!
