Its always a lot of fun to hear opinions, likes, dislikes of chainsaws, enough variables that it seems no 2 people will usually agree. What works best is how I look at it, more so if you make a living with it.
My neighbor 1 house down and across the lane, only 3 of us on this road, he and his dad owned a small engine shop, mostly deal with saws though. Go in there any time and look on the repair shelf, many older saws are still in use, be a great question to ask the customers of this shop. He kind of retired, sold the business to his partner and just works there a couple of days per week. May of 2010, he had a 30"-36" black cherry come down in his yard, and he keeps the place absolutely meticulous, I talked to him about getting that tree out immediately, put my make shift forks on the tractor, line up to the tree, he's got 2 old saws going, cutting easily, well cherry always seems to cut easy just the same. They sell Husqvarna, and he could have any one of those, still uses the old ones, and I'll be darned if I can remember what it was. Red, they could have been Jonsered, going to ask him next time I see him.
When I was a kid, my father had a Stihl 08S, with I think a 20" bar, remember that from the early 70's, in those days, this place (where I live now) was hedgerows and ag fields, with about 12 acres of hardwood at the very top a nice size ridge with almost a 360 degree view, 650' in elevation. We did some firewood, but the place was clean, just took dead or fallen trees from hedgerows. That saw was hanging on a hook in the garage for years, I took apart the carb, cleaned it, never touched any settings, fired it up, and did a days work with it, used to keep it running by using it occasionally. He needed it and it ended up at the other place. Years later, I find it in the barn, in a stall hap-hazardly left in the dirt amongst other things, well it might have been off the ground, butlike many things in life, our tools do have meaning or some other importance to us because of who they belonged too, I asked him for it, because I hate seeing things left like that, it ruins them, and or someone would have stole it, I've safe guarded many things similar, mostly so they did not disappear. Today its on my work bench, needs a bar, probably a chain, sprocket, carb kit by now, but she ran and cut very well, really ought to fix it up and use it every so often. I have a MS 390, which minus one $9 fuel line, has performed quite well for almost 10 years, piston, rings and what I could see of the cylinder still look great, it starts easily, provides the wood I burn to heat the garage/basement, halfway through its 2nd chain. Sometimes getting logs and cutting firewood can be a lot of work and things don't go as planned, but when the weather is cool, crisp, sunny, ground frozen like it is this morning, you are in no rush, its good clean hard work, that is good for a person no matter what saw you have as long as it has a sharp chain and runs well.
PS, go to the doctor today, and maybe I can get the release as to when I can work again, this morning was perfect for doing wood! 20 deg F, sunny and no wind !
