engine runaway....HELP PLEASE

was trying to get more power via injector pump AFC diaphragm, had a buddy helping me and as soon as i had the cover off exposing the diaphragm he took his fat little fingers and spun the diaphragm before i could mark it vs the housing so after much swearing and name calling i continued on and rotated the shaft as best i could from the instructions provided off this site, after putting it all back together i started it up and the engine started to runaway, now i heard that this could happen when adjusting the fuel screw and i know what to do in that case but here i have no idea what is causing it. maybe i rotated it too much or incorrectly, what do i do? please help
