Somewhere here, I found a post that says to whack it on a board, pin down. The sudden stop will help encourage the pin to move.The frustrating thing is finding an adjustable with a screw that has no slot - it's just a pin driven in with a friction fit. Can't get those apart!
Obviously, do this over a box, in case the pin is really looser than you realize. On the 4”, you may need a cheater pipe to get the velocity up without mashing your fingers
