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.
