Stiff gas pedal on 74 road runner (why are there two springs on carb?)

[1967coronet]

So after taking the two springs off it works great. Clearly just need a couple good set of springs that are the right size and gauge. I did notice the cable house seems to be deteriorating leaving just the metal thread exposed. Would you wrap that with some electrical tape?

At this point I would not wrap it with black tape.
You need a new cable.

I shot the guy a message to see if he has anything similar or if he plans to get them in stock again

The springs that 70Fish suggest are
supposed to fit one inside the other
with their end attaching points being
the same. With what your pic shows,
you have spring tensions of different
rates pulling at at different angles.
The spring in a spring is a safety
feature. Should one of those springs
break, you won't have a wide open
throttle condition. I would try
installing a new set of springs before
diagnosing the cable as your stiff
pedal problem.
With the pedal up, the springs should
be in a compressed (relaxed state)
with just enough pressure to hold
them to their attachment points and
throttle plate closure.
