Carb linkage and adjustment questions

OK...so a few things were pointed out to me:

It was mentioned that the throttle return spring should be attached at the starter and not the bell housing. Changed that....no go.
It was mentioned that the kickdown linkage didn't look right. Got some measurements and even saw the old witness marks on the rod. Changed that....no go.

Then, a guy from Australia mentioned the pedal rod. I disconnected the pedal rod and got everything in the engine bay right! But the pedal rod was too short. Someone had it screwed nearly all the way in.

Lengthened the pedal rod and now it almost works. The return springs are too loose to return it to idle. As soon as the exhaust manifold cools down, I will reattach the springs at the bell housing.
IF I can get full throttle with the lengthened kickdown rod, and IF the springs close the throttle at idle, I may have figured this out.
My next concern is what, if anything, have I done to the shifting/transmission by adjusting the kickdown rod?
