Clutch Pedal Not Returning Completely

I have a 4-speed in my 66 Barracuda behind my 273. Bear with me as I try to explain this. I don't know too much about these transmissions other than the speedometer parts.. Anyways, I noticed that when I depress my clutch all the way to the floor and release it slowly, it seems to get caught right at the end of its travel. I have to put my foot behind it and pull it until it stops where it's supposed to. Like I said, it is a very small distance from the top where it seems to stick. I don't know why it's doing that or if it will make a difference when I drive. I would check and see, but the engine still needs to be started up and tuned, since I just finished a top end rebuild. Anyone have any ideas on things I could check?
