need a new chainsaw

I have a couple of Echo saws that I inherited from my father. I'm not saying they are the best saws in the world or anything, but I think they are pretty good. I've had very good luck with them and would buy another. My 55 cc Echo saw dates back to 1970, when the company was still called Kioritz Manufacturing, and despite being used hard every year (I cut a lot of wood) it's still on its original piston and cylinder.

What usually kills a gas saw is when the carburetor starts to leak air, and/or the needle valve gets clogged and doesn't pass enough fuel. Either condition will make the saw run lean, depriving the piston and cylinder of sufficient lubrication and causing scoring and seizure. You need to adjust the carb every year to make sure it hasn't leaned out.
