Have 4 saws to go into the shop.. all Stihl saws. 023c .. love this little saw cut like a pissed off cat for its size, 2 - ms250s and a 029. Don’t have the time to mess with them. All run don’t won’t stay running long. Carbs? Coil? Not sure. Either way one or two are going to go. I use my 331 or 460 most of the time.
