I'm a chainsaw fanatic. I currently own and use 4 saws. An old Husky 51, Husky 455 Rancher, Husky 562XP and a Stihl MS250. The 51 is almost 20 years old and still runs well, the 455 I purchased in 2011 and it is starting to have problems. It probably needs a carb rebuild. I got the 462XP last year and it is a beast! I have no idea how old the MS250 is as I purchased it used. I don't think it has seen a lot of use by it's appearance.
I am a tree farmer and also burn firewood for my primary source of heat. Each saw has it's own intended purpose. For felling and bucking I grab the 455 or 562XP, for limbing and the smaller stuff my go-to saws are the 51 or MS250.
I couldn't imagine going into the woods with only one saw. I go prepared for the inevitable pinched bar, i've been sawing for more years than most on here are old but no matter how careful I am I still on a rare occasion pinch a bar.
Just yesterday I felled a "dead standing" red oak. It was an honest 33" on the but cut. I certainly appreciated the power of the Husky 562! I could of felled the tree with the MS250 or even the little 51 but it would of been very time consuming.
All of my saws were purchased new except the Stihl MS250. I purchased it from a member on here last year. It is also the saw with the most problems. Not blaming the seller as the saw ran great for the first couple of months, then it started acting up. Hard to start, when finally running would only run for a few minutes then shut down. After two attempts to clean and repair the carb I finally broke down and replaced the carb with a new one yesterday. So far so good, not had it in the woods yet so time will tell. When it runs it runs well. My biggest peave is it doesn't have compression relief nor a primer bulb. But so far with the new carb it usually starts on the 3rd pull.
