I bought a couple of new saws about a year ago, and they are a 151tc, and a 261cm. I have used the little 151 several times after getting rid of the limiters on the carb and adjusting it so it runs the way it should. It’s a great little saw once it’s adjusted so that it’s not pig rich. Well the last couple of days I took the 261cm out with my tractor, and have been cleaning up a bunch of fence lines on my property. I had a couple of big oak trees that had got blown down a while back, and decided to start the clean up. The 261cm is a lot of saw in a small package. Yesterday I was out by one of my neighbors cleaning up the first one. He was watching how good my saw was cutting, and had to come over and check it out. He couldn’t believe how well it was cutting for me, and I fired it up and let him try it out. He made one cut, and he couldn’t believe how it cut and the power it had. I did another section of fence today and got the second blow down cut up, and a bunch of limbs and saplings cut. The 261cm is a pleasure to use. pretty light weight, and gobs of power for the size. I can say I am extremely pleased with both of these saws and would buy them again if needed.
