If my 727 shifts too soon, and too soft, which way do I adjust?

Ok, u have the 3 piece linkage right. Everyone wants u to adjust it at the carb, but when u can’t get it right u have to shorten the rod at the carb so it has less travel. Then adjust the down rod at the bell crank making it longer. This adjustment is the most critical as then u can adj the rod at the carb so the carb will fully open. Most ppl don’t do the down rod adjustment because they simply don’t know and nobody recommends it as they don’t know/understand it either. Also the rod at the carb to be set correctly needs a 1/8 drill bit slid between the carb stud and the slot at wot. Kim

And that is if his pressure is right in the first place.



Along what Kimmer says, might be worth looking to see that you have the correct length lever on the transmission too.

Good call, thank you.
That gets overlooked, but could make a huge difference in the geometry being right.
