Just had my daughter press on the gas and my wife mark the kickdown line where the adjuster screw stopped and I looked at the kickdown lever to see where it was stopping. I think I have it at the "perfect" spot right now.
Only thing I can think if it doesn't work is the kickdown lever isn't pressed all the way down due to the screw hitting the shifter lever it sits on top of. I have a 904 and put the 727 shifter lever on it because it was straight, with it being straight and not dropping down if I put the kickdown lever all the way down the screw scrapes the 727 shifter lever.
