Appreciate the hint.
I looked at an "On Line" exploded view of this firearm. I also had a how to disassemble manual ... which was a hoot, because not one word about how to reassemble !!!
Best I could tell "Action Lock Lever" was the name give in the exploded view to a metal "ear" that is at the base of the stock, aside the trigger housing. Some how the position of this works in conjunction with the abiity to cycle shells.
When it sort of "bounces" upward-downward as I try to cycle, the action jams about half way to close. When it does not bounce, it cycles fine.
I am familiar with the two parts that you described. I played heck keeping them in their proper slots during reassembly. I have give up and am taking it to a qualified gunsmith.
