decent saw, ships lean
Very nice saw at competitive prices new compared to those top name brand "pro" saws. Whatever you do, wherever you buy it, take it to a dealer, pay him his vig, and have it tuned first/adjusted. Then follow the breakin advice, and take it back again for a retune after that period. They are just too lean outta the box, probably from having to meet EPA regs.
Don't ask me how I know this..good thing I bought two...learn from my mistake. But now I know, so things are much better (thanks to this site actually, I've learned a lot here)
Incredibly easy to start saw, BTW. Pull choke, yank, it runs. Mine starts that easy even without using the decompression valve button.
I personally don't think I would want to run the 27 inch bar very hard or all the time though, in hardwoods anyway, and I haven't tried it at all in any big pines so can't say really. Probably no more than the 24 in anything (even though they say it can run the 27..why beat on the saw??), with the 20 it is pretty good as a firewood saw, perhaps an 18 would be even better. I have no experience with the longer bar, but with the stock 20 it seems just about right, so why push it, you can cut rounds of hardwood with it heavier than most guys can pick up, so what's not to like? Seems plenty powerful enough, and if you follow through with the dealer adjustment and stuff, they have a spiffy five year homeowners warranty. You really want to run a much larger bar all the time, you most likely really need a larger displacement saw like in the 80 cc class.
Biggest secret to effective chainsawing is keep them things clean, CLEAN them after use, well mixed fuel, as in shake it up real good before using, don't use mix fuel that is all that old, as in at least every month get some fresh stuff, and get the appropriate round and flat files and learn how to keep an effective sharp chain. A guy with an itty bitty saw and a really well maintained chain will out cut a much larger saw with a dull chain. Seen it too many times, guys on jobs I was working (back in the day) trying to sand paper their way through logs, can't stop and put a fresh loop on or touch up the chain. The echo I got is my first true mid range saw, and I cut for years with little under 40 cc saws and cut a lot of mambo stuff with them, just because the chains were sharp and I know not to push things. Let the saw cut, you don't need to do much else but steer the things..heh.
