Stiff pedal with kickdown hooked up. Help please!

yup, thats what im not getting....everything unhooked from carb and the carb linkage itself moves freely with ease. move just the gas pedal with nothing hooked to it and it flops around with no resistance. move the throttle pressure lever at trans with nothing hooked to it and it feels to have about the same or slightly more resistance than that of my carburetor linkage (maybe as much resistance as my carb linkage would have with one spring on it but still not a labor to push it by hand really.....I can push it with 2 fingers). Move just the cables inside of their housings and they move freely. Hook throttle cable up to carb and I can pump the gas pedal and it feels normal. hook one or 2 springs to it and it still feels normal with just a little added foot pressure needed. But add the kick down cable into the mix (springs or no springs even) and its ridiculously stiff.

I know....after all that....it would sound like cable. but I have tried 2 new cables, both of which are routed correctly and without bends or anything.

mind boggeling to say the least lol. Ill get some pictures from under the car tomorrow and post them up for you guys too see.

Thanks again for the input guys.
