When tuning by the instructions fail, check where you stand by ear, what is your current high resonance best point. Tune/trap a high am station, try to trap am 1510 WLAC Tn. -  or whatever you find around there - align the dial at the known station, then dial it in. Then tune the if compensators, aircap compensators, and oscillator compensator until you have that station the best it can be. Tune down to lower station, maybe Nashville 650 - see where the dial is. Retune to see if what best signal you can get. Go back to the high station again and dial it in. Then apply your signal gen to see what if frequency zero beats, might not be what the instructed if calls for. All this gives clues as to where you stand with the machine.
