Help need suggestions & advice

Well my retun springs are not too stiff, they are accually pretty soft. I know its the throttle valve cable causing the issue on mine. I have my throttle cable racket adjusted all the way up and it does make it a little easier to pull forward.
But i'm starting to think that the edelbrock carburetors aluminum body structure is just not strong enough to support a throttle valve cable period.
I could buy another brand new throttle valve cable, but this cable I have is not very old and it operates smoothly when its not hooked up to the transmission.
