The ECHO chainsaw CS-490-18 features a 50.2 cc The ECHO chainsaw CS-490-18 features a 50.2 cc professional grade 2-stroke engine and 18 in. This chainsaw is lightweight for its class and is great for large landowners, farmers/ranchers, firewood cutters and homeowners. Just like the OEM that originally came with the chainsaw, said original Echo product and came in sealed packaging. Only didn't have the echo sticker on the side. Nevertheless, this appears 100% genuine.

Echo Autotune Chainsaw Reviews
Couple questions about a couple Echo saws. I have an CS 306 and a CS 400. Both run just fine. The 306 is a few years old and the 400 is pretty new. Only had if for a couple weeks. The thing that I’m finding about the Echo saws that I don’t like is the carb adjuster limiter screws. How do I deal with them? How do I get them out then how do I tune once their out? I’ll let the CS 400 at the factory recommended setting for at least 5-6 tanks of gas but I want to see how this thing will really run once it’s broken in. In retrospect, I probably should have bought a slightly bigger saw in place of the CS 400.
Muffler mods… I took small baffle off the outlet of the 306. I’d estimate that it change the final exhaust opening from about 1-1/2 inc by ¾ inch to 1-3/4 inch by ¾ inch. I suppose I should measure it…. But it’s noticeably louder with a sharper sound. The real question is, ‘how do I tune it to ensure that I don’t burn it up? How do I deal with those adjustment limiters? I’ll start messing with the 400 in a couple weeks.
Thanks
