Slow slutch pedal return

[sb400]

On my '79, the clutch pedal is very slow to return all the way to the top of the travel. It doesn't seem to have any hangups until the clutch is engaged, but in "free play" mode it moves very slowly. It seems to be worse in the cold weather.

I recently replaced the clutch. At that time I had the z-bar out, cleaned it up and repacked it with wheel bearing grease, along with the clutch fork pivot ball. I'm a new owner, and the truck didn't run when I got it so I have no idea if this problem existed before I changed the clutch.

It has the return spring under the dash, which appears to be hooked up properly. There is also a return spring underneath, connected to the clutch fork and a plate under the motor mount.

Any ideas?
