It's important to note that the plastic or nylon nut must be threaded completely down to the head of the screw where there is a groove for it. Without that plastic nut, the screw could loosen up during use and fall out. Likely why mine went missing to start with.
The saw is an old model but runs good. Glad to be able to find parts for it to keep it going. New saws aren't cheap.
Chain adjuster fell apart.
