There is one true Stihl fix-em dealer who does repairs within 20 miles of my house. They work full time on Stihl POE. Some of the others have a part time (retired) guy that fixes them at his home shop or they send them somewhere else to be repaired or maybe even have a certified repairman but he works mostly on other equipment.
That is funny because I am that (retired) guy that works part time. If it has a 2 cycle engine on it and can be put on a bench I do the repair work on it.
I did a small tiller, 2 chainsaws, and 2 weed eaters today.
There are no dealers here in Cheyenne that sell and service exclusively any one brand of chainsaws that I know of.
