Lost a nut from the housing of my chainsaw. Nothing available locally. Ordered it here and received it within a few days. And of course it's the correct part.

Simply replaced the parts. I have ordered parts from you before for other saw repairs that weren't quite as easy as these. But these repairs were easy because I was able to get exactly what I needed from you. No telling how long it would have taken me to go out on my own looking for these parts. Your website and parts diagrams make it easy to do repairs even if you're not "mechanically inclined".
