alright, echo fans, I have a problem with my saw and am asking you experts for information and help.
I have a grey body cs-440. I recently ended up running it too hot and scoring my piston a bit, and now I am worried about my saw. full disclosure: I mix my own gas/oil, and NO ONE ELSE here at the house uses my two stroke gas. I have the chainsaw, and old craftsman 2-stroke rototiller and an echo string trimmer. I mix it to echo specs, which I think is 50:1. After my saw started getting silly, I looked up the carb adjustments, and found that it was as far rich as it would go, with the limiter caps on. I was not comfortable taking the caps off and messing with it. I checked my gas in my 2 stroke gas can, and it was discolored, almost whiskey colored, with some water in the bottom. In a glass jar, it didn't take much movement to emulsify the water into suspension in the gas/oil, so I figured that I was running WAY lean and damaged my piston.
I went and bought 100% gasoline (at a marina, at a premium price) and mixed up a new batch of gas/oil at 40:1 ratio, and put it in my saw. I started it and allowed it to idle up to temp, and maybe another 5 minutes, then went cutting. It cut well, didn't have any bogging issues, didn't stall, didn't get "stupid hot".
so, getting down to the real issue. I want to replace my piston and piston rings, but all I can find is the "piston/cylinder kit" from echo, for $200. Are there any other options as far as that goes? it was a sub $300 saw when my father in law bought it for me, and I am struggling with putting $200 back into it, when there are used saws with more power, and built for heavier work available for around that. I am acquiring another saw, but don't want to call this one "junk" just yet.
More disclosure. I heat my home with wood, and an indoor woodburner. I just started getting logs delivered from a land clearing company, and am doing all of the cutting and splitting myself. I like my echo, it has been good and comfortable to use. It has been reliable until just recently, but maybe it is not the right saw for what I am doing right now. So where can I get just a piston and rings? Help a brother out.
oh yeah, one more thing, in looking it up, there is a distinction in the line someplace, so the serial number is important. it is 08064522
thanks everyone.
