Hi all, I have a Stihl MS171 chainsaw from new for about 2 years, it's never really been worked hard, just used for cutting felled trees and branches into logs for my fire.
I've always used Stihl chain oil and 2-stroke oil correctly, and kept it serviced with genuine parts.
I came to use it the other day and it always starts fine, but after a few minutes of use it starts to lack power then stall. The choke isn't on and the fuel tank is full. I checked the air filter, but it was fine (it was serviced just before winter). I wouldn't have thought the crank seals would have gone this soon - or would they???
Any ideas welcome as I want it in use to cut up logs ready for next winter.
