In my experience you can expect the shutter to run a bit slow. Capping and dragging is also fairly common, but is sometimes simply a symptom of a lack of use and will clear after some exercise. Whatever you do, do not try to "clean" the shutter by dripping lighter fluid into the camera, you will cause the shutter curtains to come unglued from their spindles/drums. This sort of thing can be expected of any camera that is 40 or so years old.
