I just got mine this week and put a couple tanks through it last night. I'm running a 32" Tsumara light bar with 3/8 square grind chain. So far, I'm thinking it is totally freaking awesome! Tons of power, I like how it handles, nice power curve, fires right up. To me, it really feels like a quality saw. I have a 372, a 395, a 660 and 572 that I frequently run. The 592 is lighter and has noticeably more power than the 395 or the 660. It seems to use considerably less fuel than either my 395 or 660. One thing I did like was the power curve is flatter than my 572. The 572 is a screamer and doesn't have much lugging power, but the 592 has power in the midrange and high range. It is definitely my favorite at the moment and fear it has made a bunch of saws obsolete.....lol
The only two things that are a little strange is the fuel primer bulb never gets any fuel in it? No matter how much you pump it, it just has air in it. The saw starts and runs fine, so I'm not going to worry about it, but it is strange. The primer bulbs on my other saws all have fuel in them. The other thing, which I am a little embarrassed about as I should have just left it alone, is the decomp valve. I hate decomp valves. They cause problems, I think the saws start harder, and if you are man enough to pack a 90cc saw around with a 3 ft bar, you don't need no decomp valve. Anyway, I usually just take them out and plug them as soon as I get a new saw. Well, this one was in there WAY tight. When I took a 3/8 ratchet to it and backed it out, part of the threads from the cylinder came with it. I don't know if they used some kind of sealer/glue at the factory, or it was over torqued at the factory or what, but there was barely enough thread left to hold the plug. The plug is in there for now, but I bet I'll have to heli-coil or JB weld it or something in the future. Dangit, that is irritating.
Anyway, all thumbs up on the 592XP. Go get yourself one! Kind of like Grain Belt Beer, how in the world do they make it so good and so cheap! lol
take care, Cody
