My experience with the 361 if this. Look on the clutch side just below the bottom fin, and if you see STIHL it is not a Mahle cylinder. You can see it right there in the shop without removing anything from the saw.
A MAHLE cylinder will have the name right at the base and and is only visable by shinning a strong light on the base of the cylinder and then HLE is visable.
And if it is a Mahle cylinder that doesn't mean its any better than a Stihl made cylinder regardless of popular opinion. How do I know, I've replaced exactly 1 cylinder on a 361 out of 100's of 361's I've sold. Belonged to Volks-man, member on this site. The cylinder had a small pit in the coating of the cylinder wall. You could see it on the intake side looking through the exhaust. The coating had chipped and left a small pit. He didn't like the looks of it and wanted it replaced. It ran fine but that small pit bothered him. It was replaced at no charge. Name on the cylinder, Mahle. Volks posted some nice pics of that thing on this site. Was no up roar though, just a bad Mahle cylinder out of millions made. Why no fuss then, answer is simple.
