Accelerator cable, sticking or tight acclerator cable-causes? Options

[DRPHIL914]

Accelerator has always seemed tight, like it takes 2x the foot pressure than it should.

Throttle body does not seem sticky, but could it be a really stiff spring, or is the cable just tight/gunked up?

it is a 75 2.0 and i have had it for 1 year, no idea if it has ever been replaced.

another thing, though, If engine is warm, been running for several hours, and i go to stop, clutch and let off accelerator cable, it is slow to decelerate. I do not see this just much just drving to work in the morning(20 min).

How hard is it to run a new accelerator cable?

Ok. Well, i spent some time looking at each end on this. The throttle body i think is o.k., and i do not think the return spring is the problem. when accelerated at the throttle body by hand it pops right back. I actually think it is the pedal itself causing the problem, or the front linkage that pulls the cable when the pedal is pressed upon. I had checked the clearance at the airbox- it is close but not the problem. But just because it is 35 years old, i am going to do the following;
A: replace the cable- new one on the way;
B: since i have a rebuilt clutch/brake pedals from SUNAB914-chris, and i have a new pedal board from the Group Buy(aluminum) that i was going to put in, i will pull the old board, replace the pedals, lube or replace the linkage for the accelerator, put the new cable in and see what happens.
I think Als914 has good suggestion, my speedometer cable is bad, too, so going to do both at same time.
Will let you all know how it goes, but hey, any one have advice on shift linkage bushing replacement- another separate issue right now?
anyway, should be done next week.
