I've had a few Chinese Husqvarna 365 saws, a few not because they were bad, but because I needed money at the time and sold them. My latest one was nowhere near as good. It was tuned super rich, but leaning it still wasn't nearly enough. It did come with an "Oregon" chain exactly like a super RS which is durable and aggressive already, but I filed the depth gauges and now run on about 101 octane with around 1.5% nitro, and it's equal to or better than an ms390. I was beating my friend's ms 390 (which I had topped off with my same fuel) today on 20" oak log, but I think a little might have to do with operating skills. I shouldn't be surprised at my 65cc beating a 64cc except without closely comparing them I've always thought the ms 390 ran like a husky 372. So, I don't think nitro is all that bad if you keep the quantity small, 1% shouldn't hurt, but makes a huge improvement with no tuning needed. I think you can go up to 5% with no tuning. I think my saw would now be competition to a 372. I'd upgrade to the 76cc engine, but I don't know if the Chinese parts are compatible. I'd probably trust 2% in a real husky now. If I can find a more than good price on a 395 and can afford it at the same time.
