Definitely Not the official procedure:
Just a very basic "ballpark" place to start from that will get you 'close' and likely need some further adjustment. But with any luck will be driveable so you can continue adjusting as needed.
With the fast-idle cam on the choke mechanism out of the way... have the throttle linkage at the idle position, with all throttle return springs installed. Remove the TV rod from the bellcrank lever arm.
Pull up (firmly but not too hard) on the TV rod. Count the number of turns (clockwise) needed on the adjustment link until the pin aligns with its hole in the lever while the TV rod is held upward.
It should be about 3 turns. If it is, unscrew (lengthen) it back to the same place & reattach.
If it wasn't... from the point where the pin lines up with the hole, unscrew (lengthen) the adjuster link on the threaded TV rod 2 & 1/2 to 3 turns and reattach it to the lever. Test drive...
Adjust for best engaging and shifting in one-half turn increments. More than one full turn in either direction should not be needed.
I likely shouldn't be offering this advice. My '55 with Fordomatic is a mixed bag of mis-matched parts that was barely driveable with the adjustment as it was. The linkage parts it has are from different years/don't quite match the book so I had to fake it. But it engages & shifts much better than before.
