Clutch pedal sticks

I’m having a problem with my 73 duster clutch pedal. Here’s what I’ve got going. I’ve got a 1970 Plymouth duster that I converted from an automatic to a 4 speed 833. I’ve already done all the converting like stud ball on the frame and the transmission. I’ve got the z bar in along with all the plastic bushings that go on the ball studs and all the stuff on the linkages. I bought a kit with everything to rebuild the linkage. So I know all that is good. My problem is, when I push the clutch in it will go all the way to the floor just as it should but when I let off of it, it will only come back up halfway. Then I have to pull it the rest of the way back up with my foot. It’s almost like it’s got a spot about halfway up that it sticks. When I pull up on it just a little bit it will pop all the way back up. I thought it might have been my linkage but if I unhook the linkage it still does the same thing. Do all 4 speed clutch pedals stick like this? Any advice would be greatly appreciated. Thanks in advance.
Go to a home improvement store and buy a package of builders shims. Have someone hold the pedal down while you stick a few shims between the coils. You'll probably have to break them off to get them out of your way. When the pedal is released the spring will come right off. Leave them in there in case you ever want to put it back on.
