Horizontal scorching
Let me start by saying I know very little about chainsaws short of watching YouTube for trouble shooting. I was able to pick up this Stihl ms250 for 80 bucks on marketplace the gal said it wasn’t running but for 60 bucks I said screw it worth the risk.
To my surprise it fired up no issues it was a bit of a tough start but Idled great. I was wondering if I should be worried about these horizontal scorch marks on the piston all I can find online is regarding vertical lines and pitting. Thanks
