The powerhead is just dirty. I don’t put much if any stock in what the bar is like.
Here in mesquite firewood country a bar’s life span is 10-15 cords of wood. If a guy runs chains too long I’ve seen bars smoked in 2-3 cords of work.
It’s pretty clean under the dust and oil. I look at percentage paint left on the front of crankcase and the bottom.
AV is tight still. A 361 with 100 cords on it has pretty loose AV.
Here it is next to a huztl 360 that I’ve put 2 tanks through breaking it In and working the bugs out of for the guy who built it. Guy (my brother) told me to run 10 tanks and tell him what it needs to be good to go. Notice the bar on it is rough because I grabbed an old one off my bench. I didn’t want to put wear on his new bar and chain. I doubt I’ll make 10 tanks since it’s a lot slower than the big saws I usually run but he did a good job building it and so far it just needs a stihl Oiler and maybe a softer spring on the carb, could use an extra 6” of pull rope.
