I had the chance to cut with one of the new Echo CS-620 saws last week. We had the CS-590, CS-600 and the 620 all in a row and cut from the same log for comparison. The 590 is no slouch, and for the money there isn't another saw built as well, but there was a noticable difference going to the 600 then the 620. I think the 620 was 2-3 seconds faster through a 10" diamater hemlock.
Also the 620 will be available with a wrap handle and double spikes from the factory. I cant wait to get my demo saw so I can break it in and really see how it wakes up.. Oh, in a bizarre occurance, the 620 was set way rich from the factory, almost 3/8 of a turn to lean it out so it wasn't gurgling.
 
Its so new that there are only two in the field in the northeast. Its based on the 600p, same displacement but new ignition and some other stuff. Weight is the same as the 600p, a little more for the wrap model. The 550p is going away, and no pics, I only had a few minutes to run them being a Monday morning in a mower/chainsaw shop.
 
At a local echo dealer, I have seen the 590 and the 600, which I think has some upgrades since it first came out. I hope eventually to run some of these new models at a gtg sometime.

That's actually kind of a disappointment. It's just another iteration of the 600p. That makes 3 saws that are essentially the same. The 590, the 600, and the 620 are all 59.8cc. And with the first gen 600p that actually makes 4 versions of essentially the same saw in 3 years. I was really hoping for more cc for the same weight. I love my 600 and would buy another in a heartbeat, but how many times are they going to spin the same saw? Any word on any truly NEW saws coming down the line?

BTW I may still end up with a 620, to upgrade from my 1st gen 600. The wrap handle and strato/new ignition are enough of an upgrade in the same package to make me want one none the less.

If you want an upgrade, get the one you have ported. The difference is unreal.

Wrap handle-yes, strato-no, echo is doing away with the only strato they had in the 550. I would like to see a 65-70cc saw in that chassis as well, and have suggested it at every opportunity, the chassis has the girth to handle more power, but Echo's feeling is that competing in the 70 cc market with 372xp's and 441's isn't worth their while.:(

I had to open up the 600 and see what was inside... It's a very nice jug. Likes to run without a base gasket too..:msp_rolleyes:

Just a tick more intake duration helps too...

One would have to cut the squish band to get much more compression though, as the combustion chamber is huge...

The 600 you let me run wasn't that bad. The cylinder looks great from your picture. How many thousandths would it take to get a noticeable jump in compression? :msp_w00t:
