Echo cs 490

[James Miller]

Mine now has the muff opened and and the front of the deflector cut out and retuned after 5 or 6 tanks. Its a strong saw and keeps getting stronger iv been told 8 to 10 tanks before they start giving all they have. I find my cs590 sits till the wood gets to big for the 16" bar on the 490. Mostly oak and other hard woods around me and this saw will pull the 16 with full chisle barried all day and not complain. I'll get pics up of the muff and deflector mod in the morning.

I got to play with the 490 a couple weeks ago. Not a bad little saw but could tell it really was restricted on it's breathing. Would like to try one with a mm

I got a MM 500 I'll sell. It's had the whirly do-dad thing stuck in it too! lol.

The 490/500 are really close to the same. Saw. I love how light they are. And there well built. That said though there one of the worst PRO 50cc I've ran in stock form. However with just a little work there a huge gain saw. Starting with the MM which makes a really good difference.

@BGE541 the stock numbers in this saw is something like 120/130/80ish. Gotta get that exhaust up to make a runner. But they run good once ya get them there.

so a base gasket delete with the stock numbers is not really helpfull ?

So this is my muff that tube sits under the spark screen the rest of the muff is empty. Pull tube, cut the front of deflector out, retune. Runs much better once I opened it up.

It will add comp but just makes the exhaust roof even lower.
