"If by alot of them running you mean they get started and ran out of pity, then yeah I'd agree. " Huh.....I really don't understand that one. I never ran my 044 out of pity. I ran it to get the job done. If I could get that saw back I would run it another 30 years. I had an 051 before I got that 044 and I ran that saw for 15 years or more and the only reason I parted with that was because of the weight but boy would that thing cut. I don't no anything but what I have personally seen with my own eyes. As far as the filtration system All I can say is that I could put it on a log pile and run it all day and not even think about stopping to clean the airfilter. About once a week when cutting hard I would clean the filter, put on a new chain and wheel, touch up the bar and cut for another week. I would touch up the chain about every tank full or two of gas, especially in dirty wood. It would go through a tank of bar oil for every tank of gas. In dirty wood, it was time to tighten up the chain about the time it ran out of gas.
That saw ran 8 to 10 hours a day sometimes for months at a time and never was down because something broke. That is if you don't count the time I ran over it with my 955 cat. luckily it didn't hurt anything but the bar and chain and that time I was up and running in less than a half hour or so.
I never thought too much about the vibs, it never seemed to bother me and at the ripe ol age of 75 I could still run her all day every day. I won't say it was fun for a few days after I wont cutting for a month or so but once I got back in tune I was ok.
I doubt I have 30 more years left, maybe 10 more the way I do now and my only hope is that there will be something left to pass on to my boys when I'm to old to run it. The last things I ever plan on giving up is my chain saws, my pickup and the firearms I have collected over the years......and my wife, as she has been pretty tough over the years as well.
