Do you mean there is no difference in porting between the 590 and 600, or between the 600 and 620? There is much difference between the 590 and 600 timing numbers, as I have ported more than one of each. The transfer tunnels and upper outlets are also shaped different, and the cylinders are different part numbers. Here are the stock timing numbers:
600P
EX 113/134
In 102/156 or 78 from tdc
TR 133/94
590
EX 113/134
IN 103/154 or 77 from tdc
TR 128/104

have ran both 800 and , 670 ... not the saws that the 590, 600, or 620 are AWOL is working on a 670 now
it was poopy slow compared to a 600p or 590. the 8000 pulled hard but wasnt much wow factor
i would think both saws could be cool with a little grinder work, i also bet both bigger echos are rock solid reliable

the 8000 I ran wasnt bad, kinda ran like a reed valve , kinda
i compared the 620 directly to a 590 in the local atwoods the other day.
the 620 i looked over had a 24" bar and chain, and a plastic clutch cover-- looked identical to the 590 on the outside except for the plastic handle and the 24" pro bar and chain.
it was $240 more than the 590 with the 20" . my local husky dealer also sells echos he didn't have a 620p in stock at the time i bought the 590.
all the 590,600p and 620s look a lot the same-- i think the 620P has those big bar nuts-- i don't think you can go wrong with any of those three.
a 620p would be interesting as it has more power than the 590/600 -- since i have some time to run the dickens out of the 590 i can say if they 620P has 20-23% more power than this 590 or was it 600 ? --it is going to be a "factory" hot rod of sorts for its size. a little over 5hp from 60cc ain't bad at all--

according to saw troll these saws need to go in the trash he said the power to weight is low and the price means low quality
well numbers don't mean anything when it comes to real world testing my saw ate a 55 rancher the other day and embarrased a stihl 039.

compared to the husky its better because it doesn't leak oil everywhere
The numbers I was given were the same on both saws. I do know when I was doing my research, both the 590 and 600 cylinders had the same part numbers, that was changed last summer I believe. From your numbers it looks like any real cylinder performance difference would be in the transfers. Are the exhaust and intake port shapes the same?
We also may be dealing with supply issues. Quite a few manufactures would upgrade the cylinder on lower displacement models if they ran out of cylinder. Poulan did this all the time back in the day. I'll degree my 590 and report back.

Same thing on my Oleo Mac 962. Mine is a 2013 version with quad port, although the original was only dual port.

Yes sir, the In and EX Ports are the same shape, and the EX port is at the same height, the IN is only a tiny bit lower on the 600.
There are also two generations of 600 saws, each may have different numbers. The only 600 that I degreed stock was a late one. Sure would like to have one of them 620's to take apart and compare!
Same here my CS8000 has no where near the RPM of my good running 385xp but holds it's own in cutting speed with a aggressive chain. Steve

Interesting numbers. The variability of timing numbers from saw to saw (different manufacturers) is quite diverse.

Yes it is. Even the way that two different people measure the timing on the same saw can vary widely.
What I found interesting on these Echos when I first checked them, was the very low Ex duration, and comparatively high In duration. The high bore to stroke ratio must make this necessary, because raising the EX up to a more standard number does little for performance, the saw still has a low powerband.

37mm stroke I think.
i made the mistake of quoting in a thread the 600 part numbers when comparing these saws. 600 is totally different saw than the 600P. when looking at the ipl for these saws be sure to compare 590,600P and 620P.
http://www.arboristsite.com/communi...s600-cs600p-cs620-cs620pw-differences.257613/ very first post is parts numbers for the major components and at the time it was posted they were all current parts numbers.

Stock squish with gasket was .039 for the 590, and .041 for the 600. Both models have a very shallow and wide combustion chamber, so the stock squish band is very narrow. A small amount of material removed from the band and base made a large increase in compression.
