Just an update... I oiled it and the pistol seems to be shooting fine. I do not yet have a chrono, so I don't know how FPS. I am still concerned that some of the degraded/melted foam is in the works. It would be nice if I could have someone take a look, maybe clean it up a little, maybe make sure things are well adjusted.I have taken apart a Crosman 2240, but I am reluctant to open up the IZH.
