4 speed clutch

[1993F250]

Hey all. So my buddy just picked up a 68 high boy 390 with a 4 speed. When he was looking at it he said running or not if u put it in any gear nothing happened. No grinding no movement nothing. The guy told him something got stuck and he pried on the linkage and it hasn't moved since then. We towed it back to his house and now it goes into gear and moves. We've successfully moved it forward and backward. However we cannot get the clutch to disengage. The pedal is moving the clutch plate in and out. I can still see grooves on the plate it all seems ok. While its running and the clutch is fully depressed it makes a bit of a rattle kinda noise, the clutch plate moves out, however it does not release to shift into gear. We've backed out the adjustment screw a considerable amount hoping it was that. Now just looking for some suggestions.
Any help is much appreciated.

When I was doing the cummins swap the motor sat on a pallet for well over a year and when i got it in and running it was doing the same thing and I finely figured out that the disc was "stuck' from sitting for so long so I started it in gear with the clutch depressed and the E brake on and the wheels blocked real good and the jarring of it firing up without the clutch engaged was enough to get the disc to come free

Oh man perfect suggestion. No idea what this guy had a problem with before, hopefully we don't find out. But I did exactly what you said and its running good now. Very much appreciated.
