Don't listen to anyone who tells you to leave it disconnected or to wire the arm all the way back or any other shadetree BS. Follow the FSM procedure and adjust it right.

He builds them so I guess he knows what hes talkin about... 79 B-200

Basically the same stroke as the gas pedal. gas pedal up, lever is forward and relaxed,,,,, gas pedal down at full throttle, lever is all the way back. Basically simple if you have all the stock linkage. Mine is all Lokar cables but works the same. Any yes you can tear up a good tranny if that kickdown is not adjusted right. 727's are a little tougher than most but it can't be adjusted wrong forever.

Any way I'm only interested in theory rather than actual adjustment since I will be altering (if needs be) my present linkage to suit my Edelbrock setup. By the way Heavy the adjustment procedure (for stock) is covered in that ATSG Manual I linked earlier, but not where the lever is at different throttle positions which is what I'm looking for. What Phoenix said basically agrees with my interpretation at this point though.

Basically it says to make sure the engine is at temperature, open the throttle just to the curb idle notch on carb lever (make sure choke is open). Then from underneath the van loosen the adjusting screw and let the spring make the actual adjustment (the spring yours is missing at the moment Heavy). Note: Manual says to make sure the throttle valve lever stays all the way forward during the adjustment.
