Throttle linkage question

the vertical adjustment is back at the bellcrank. it snaps onto the ballstud of the bellcrank. to set it, unsnap it from the ballstud, line up the little holes on the bellcrank, put a drill bit thru the little holes, and then thread or unthread the part on the vertical rod so you just barely have to pull up to snap it back on. then set the one at the carb.
