What hasn't been said about the 361, I'm open to any brand, that's why we recently added a Husky 346xpne to the work saw pool. Never run a Husky 262, but run quite a few saws over the last thirty five years and of all the saws I've used the 361 is the best pure firewood, all around farm saw I've ever run. We've run it for 2 1/2 years and it cut the majority of the 370+ cords this year and over 100 the first year and a half. We have done nothing to the saw but add mix and bar oil, and replace the bar as I bent the hell out of the original. We only have ours muffler modded and run a eight pin sprocket and 18" bar and it's a wood eat'in machine. The 038's pretty much sit anymore.
As we have hired hands it gets it's fair share of abuse from time to time and has been bullet proof. It's light, has great anti-vibe and more than enough power to handle 20" bars with ease. I'm sure the kita/dolmar is a quality saw as well, but the ergonomics and handling of the 361 are great.
The 346 is the best 50cc saw I've ever run, so far it has been exceptional, the only thing I see is that the case/handle/etc just don't look nearly as heavily constructed as the pro Stihl's, only time will tell how components other than the engine hold up, I'm hoping they do as it is a great little saw.
I would give it a little time with the saw you have, but don't wait too long or the 361's will be history. It took the 361 8-10 tanks to get broke in.
It's the start of CAD, although the 390 is a good saw, it's heavier than it needs to be and the 361 just out performs it, plus if you eaver have it go down the 390 will in most cases cost much more to repair.
