[TARNATION !!!]

Getting there today. The things you find on reassembly. I inserted the unhooking pin and spring and installed the screw. I could push the pin in but it woul not return. Spent a while ensuring their was no obstruction in the pathway. Finally decided the spring must be too weak. Sorted through my “junk” and had four of those springs. Compared them with the spring that seemed weak. That spring has many more coils of much finer wire. Replaced that with an original and all’s well. I think someone replaced an original but never bothered to ensure it functioned properly. It does now. Not much left to do. BTW vice grips for top lever spring installation not the floor plate as I look at this pic
