A good friend of mine owns a tree removing service and has been upgrading his equipment as his business grows. He is one by one replacing his well aging arsenal of Stihl and Husqvarna chainsaws, but doesn't have a lot of money to spend as he just had to replace the engine in his dump truck and buy another wood chipper.
I told him about Echo's new line of saws, specifically the CS-590 and how much saw you get for the money, so he bought one early last year and has been running the bag off of it every since, with zero issues to date. All he did was bring it here right out of the box and we modified the muffler deflector and removed the limiter caps and fine tuned it.
Recently he purchased a CS-490 and CS-355T, so brought those here as well so we could tune them before he starting working them to death.
Remarkably the CS-490 didn't need much adjustment from the carb, and I only opened up the three small holes in the deflector slightly. The "L" screw was pretty much right on and the "H" screw only needed to go about 1/8th turn rich. I spent some time with it over the weekend before he picked it up yesterday, and unlike the CS-590 it's not overly impressive for power, but decent.
The CS-355T in contrast was WAY lean everyplace, and needed quite a bit of fuel at full throttle to be happy. I didn't touch the muffler in any way, just richened it up till we got it to "four stroke" a little before putting some load on it. I didn't count the turns from the stock setting but it was a BUNCH! It had very good power for the cc's, and it going to replace his Stihl 200T that was recently dropped out of a tree and didn't survive the fall.
Not sure at this point how either will make the grade, but I'll update the thread if/as needed to let folks know how these saws are doing in a commercial environment......Cliff
