Noob question 727 really low shift points

Your kickdown should look something like this. Pull off the throttle spring, the clip and washer and pull the slotted rod off the throttle pin. The end of the slot should touch the pin or close to it to start with. If you open the throttle all the way, the linkage should be wide open down at the transmission. If yours looks something like the second picture, You need to close the gap in the slot. The slotted end screws in and out.

I'll have a look when I get home, but I actually don't remember seeing a second linkage next to the carb, I only remember for sure seeing the throttle linkage. I absolutely would not be surprised if this wasn't there after realizing how butchered this car was when I bought it and how much I was lied to about the car. I looked at the engine shot I have in the garage photos section and I can't tell with the air cleaner mounted, so I'll have to look when I get home. Thanks for the visual though, that's huge.
