Funky shift points

I adjusted the kick down linkage on the duster today per the manual and it shifts like crap. I pinned the upper bell crank and adjusted the intermediate rod till the trans lever if full forward. what gives? 1st gear is about 2 seconds and second lasts a while longer then it should.

Hold the carb at WOT. MAke sure that it is actually full open. Adjust the kickdown linkage untill it is pushed all the way back at WOT. Take it for a test drive. If it shifts too late and/or too harsh for your taste, back off on the kickdown adjustment. Keep doing this until it shifts where you like it.

Also, when the linkage is all of the way back, make sure that it isn't binding anywhere.

Also read John Kunkel's comments in the trans cooler post on this page - he makes reference to the importance of the k.d. trans lever position at idle.

Kickdown linkage is a misnomer. It is throttle pressure linkage.

well, heres what ya gotta do. take a measurement off of the old maniufold and carb, and off the "swing" of the old carb (amount of travel/distance from center of shaft) your gonna have to put the linkage back in the exact same place as it was bfore. the edelbrock chrysler adaptor does noy do this, im not even sure if they actually tried it
if this dont work, then, on a aftermarket carb, set the throttle pressure to be fully on at WOT, then, adjust back till it works right.
heres something else
i like mine to have full kickdown right when the secondary's open, and still be adjusted right at slow speeds. it takes a wide swing, and a bent tube to get this to work right
so, set it back to stock, and go from htere.
also, the fast first shift, then the delayed second is wierd, all mine have always held both gears when they werent adjusted right

Adjusting at the forward position is by the book and the book hasn't changed in over 40 years.

If the linkage is adjusted at the forward position and doesn't shift right there is something else wrong i.e. swapped carb, mismatched linkage parts, etc.

You were right! My problem was in the hurst shifter. I rigged it in neutral and when I down shifted into D,2,or 1 the trans wasn't fully engaged into the detent. I rigged it in drive and now all the gears work great and it shifts nice too! Thanks for the help guys!

What did you mean by "pinned the upper bellcrank"? I took it to mean that you pinned it to match wide-open throttle at the carb, then adjusted the kickdown/throttle to full forward position. Thats why I said "wrong way".

The bellcrank on the 3-piece linkage has holes for a rig pin, a 3/16" rod is used to pin the bellcrank and all other adjustments are made with the bellcrank "pinned".
