So I removed the set pin and expecting this plunger to shoot out and nothing happen it seems to be stuck, I do not see the spring thru the set pin hole. See photo attached.

Add lots of penetration oil.
Looks like metal is peened over the plunger pin. Might be a thin flange of material holding it in. Can you push the pin in and dress the inside edge of the hole?
