The actual replacement of the parts was pretty simple but had to remove the clutch assembly to get to it. After researching how to remove clutch on that model, which wasn\'t to simple, (I\'m not a mechanic), everything else went smoothly. It takes an impact tool to remove the clutch. Had to put some rope in the spark plug hole to jam the cylinder to keep it from turning. Found a youtube video on removing that clutch which was very helpful.
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.
