hey guys. the inner left carb on my 1973 cb350f was leaking. I took it a part for a rebuild. my question is, if you take a part one of the four carbs, do all of the carbs need to be synced again? also, if you take carb a part for cleaning, put everything back the way it was, do you need to re-set the float height or can you just put it back the way it was? thanks!
