Yes, however I just blew up my 2 year old "Lightly used" STIHL chain saw that I paid around $170. The repair with parts is around $150
All aluminum, maybe I have a unit built on a Friday late afternoon or early Monday morning.
Successful people build each other up. They motivate, inspire and push each other. Unsuccessful people just hate, blame and complain.
