Well, the stock was easy to remove; thanks all for the help avoiding the pitfalls. I did not find the screw driver set I hid, so I ground down a regular one for the triggerguard screws. Those slots on the triggerguard screws are really narrow! I never heard anyone comment, "boy those screws sure look nice with the slim slots." I wonder why they do that.
Although there did not appear to be any gunk, I cleaned things out with brake cleaner. I was not, however, able to fix the problem. The big weight is spring loaded to the forward position, but the transfer bar does not seem to be spring loaded downward. Maybe that is a problem, but what I noticed mostly is that when the left hammer is selected, the big weight gets hung up slightly and does not swing forward freely after the trigger releases the left hammer. The weight does not hang up when the right right hammer is selected. I guess that the parts are binding and need to be taken apart and smoothed up. I am not sure I am up for that, but it seems like a simple job for a smith. If the spring was stonger, that might make it work correctly also. Dan
