If the cocking hook pin and spring in the knuckle move easily but have no real resistance when pushing in with your finger then I’m guessing the cocking crank spring and pin are not functioning properly. Spring could be missing or the unhooking slide could be bound up with crud and not freely moving. It’s what pushes the cocking crank away from the cocking hook. If you have another Parker that comes apart and would like for me to illustrate this pm me with your phone number and we will visit with guns in hand. One picture is worth a thousand words.
