I got my first 026 around 8 years ago, a good friend bought it at a yard sale for $5. It was mostly torn down as far as the case but everything was there but the airfilter. I really don`t know and never figured out why it was torn down in the first place cause I found there was nothing wrong with it as it went back together. It ran fine for a couple of years but I figured I could get a little more out of it if I got to grinding on it, had little to lose if it did not work out. By then I had picked up 3 more 026`s for a total investment of $75. in all 4 of them so I figured what the heck, get to grinding and did so in steps. I have built 25 or more by now and they do really well as an all around saw for me and quite a few others. I run a 20" bar with .325 chain on my wood cutters and they pull that easily in the wood we cut, my bigger saws seldom come out now as a result of the 026 doing so well.
