Finally found the time to run a couple of tanks through the 365 this morning, it's quite a beastie! Running on Stihl green at 33:1 it sounded rich to my ears, constant 4 stroking when wot at no load but no smoke so not far off. I think it cleared up when I found a couple of big enough bits of Oak to bury the bar. Might just be my non expert ears, but think I'll give it a 16th of a turn to lean on the high screw but generally, it's a lovely saw I stuck a brand new Oregon full chisel chain on it and it was like a light sabre through the 12-16" silver birch and sycamore I mainly cut today. Overkill for that. Some dry as a bone and hard as nails quince and Apple didn't trouble it much more. And it dealt happily blocking up some Oak crotchety bits that were just large enough to bury the 20" bar Yep, I'm looking forward to a long friendship with it, my little ms180 deals with the small stuff and is nice and light, this beastie deals with the rest. Only down side, no window to see the fuel level. Seemed much more efficient than the 038 though, much more. Although it absolutely drinks bar oil! The tank is ½ a litre! But then it will be sized for the largest bar a 372 can pull....32"?
