As he suggests, shift into high and yank the cable and see if the derailleur swings further outward. if it does the cable is loose and the limit screw is probably fine--and if the screw also needs adjustment, you can't do it properly without adjusting the cable tension anyway.

I am completely serious here---having been in many situations just like this. Stand the bike up somewhere, shift the front derailleur into high, and yank the cable---see if the derailleur moves. This is the first test I would perform if it were my bike--or if it were yours and you were a friend.
