'15 Echo CS620PW Information

[James Miller]

What gives the Echo 620 such a lot of torque is the big stroke. Is has a stroke of 37,6mm for a bore of 45 mm. such a ´long' stroke would only be found on larger displacement saws.

I love my 620, best saw ever had and used till now...

How do you like your 501? I'm thinking of selling my 490 and picking up a 501 to replace it.

The 501 is also a great piece of machinery. Lot of power and torque for a 50cc and realy great handling.

What I like the most about the saw, it's verry compact, great handling abylities, and a strong and reliable engine. Echo realy did good job building their last saws, everything is well studied. And of course the stock bars made by sugihara, like the 620.

Only con: the plastic mesh filter (even if the grid is verry small). Would have prefered a filt air filter.

Here you see how compact the 501 is beside the 620

Same setup here except I run a ported 590 and a cs490.

Trying decide between the 590 and 620p. No expert on chainsaws, and not sure what difference is in unlimited and limited coil. Is there a drawback having unlimited coil such as when cutting smaller stuff?

For the average homeowner/firewood cutter 590, for the ambitious homeowner/firewood cutter/pro 620.

On of the local cities is running 590's for their crews. Cheap enough that if they do break them, they just replace them.

both are 60cc and share the same case. the 590 is a budget cutter with a cheaper clutch set up, plastic handelbar, smaller carb, limited coil, and less agressive ports in the cylinder than a 620p has -- a 620 is about 20-25% more powerful than a 590. (stock) the 620 has a "pro" bar and the 590 comes with a laminated bar-- both come with decent chains --

a 590 has about 3.9 hp stock a 620p has about 4.5 stock

i have had a 590 for several years and just recently got a 620p --both respond very well to modded mufflers and a little carb tuning.

both are good saws and very well worth the $$$

the best buy is still the 590 , with a little muffler work. -- a 620p goes for about $150-$200 or so more than a 590 new.

if your wanting a 620 get it as converting the parts over to a 590 is not cost efficient . thats why i bought a used 620p--

either scream ported--- around here a new 590 is about $400 and atwoods sells the 620s for $540

you may be able to get a better deal from one of the echo dealers on AS---

 

[BB Sig]

Also look for dealers that are hosting an "open house" or dealers day. My local store had one and I got my 620 for $420. Echo has recently dropped their price on the 620's.

Even after porting my 590 doesn't get up against the coils RPM limit. On the 590 its pretty much a non issue.

What is the rpm limit if you don't mind me asking

First poster here so forgive me for jumping right in. I'm not a professional arborist, just a farm owner. But, I'm a nut about anything with a motor and am also an Echo fanboy across the board. I like other stuff too and have used Stihl's and such on the chainsaw side but still prefer my Echo's.

With that said, I'm seeing a little misinformation here regarding their 59.8cc saws. Some of the comments are referring the 590 as a detuned 620p. Not really. The 600p came first. It is ('was' as they are discontinuing it) a pro saw. Echo took the 600p and used the plastic handle, spur sprocket, laminated bar, and plastic side cover to make the 590. The cylinder/piston, carb, and coil are identical. The 590 has no competition in the ranch saw segment (my opinion.) By that, I mean within reasonable price range. Sure, Stihl and Husky have at least as good or better saws, but for nowhere near $400. Take the fact that you can finance the 590 off the Home Depot shelf for 0% for 6 months and also buy it 20% off during one-day promotions which Echo has the schedule list on their website, and it's a no brainer in the ranch saw category. It retains the pro saw split magnesium case. You won't see that on a Husky Rancher or Stihl Farm Boss, at least not that I've seen. I'm probably wrong there.

Then Echo took the 600p and tuned the porting on the piston and cylinder, used a different carb, and of course the new coil to create the 620p. Contrary to what one of the above posts says, the 620p is 13% more powerful than the 600p/590. This is repeated from an Echo press release. It's not 25%, but it's still substancial.

Now, I haven't followed Echo's pricing on these saws over the years but they do seemed to have dropped lately. Home Depot still shows the 620p on their website for $659. Echo say's the MSRP is $559. I just came home with a brand new 620p today from a dealer a short drive away that had a 20% off day going on. The saw had to be ordered but he honored the price. He said his catalog said $659 but I mentioned the website showing $559 as well as my local dealer. He was quite surprised but agreed and took the 20% off $559. I don't really see how the 620p has much competition in the 60cc pro saw category either with that price. From what I see, the 362XP and MS362C-M are $750 saws. You also read about the Husky's straight burning up and the 362's having vibration issues and such.

It was a bit late when I got back home all said and done so I haven't had a chance to put the 620p in some wood yet. But, I did crank it up outside this evening and it sure sounds healthy. The response is very quick too. I've got a lot of time behind a MS-290 and this saw feels much more substantial on the power side. I know, apples and oranges... I bought the saw with the 24" bar but am going to pickup a 18" or 20" setup for some of the work I do around here and maybe the 27" when I need it one day. I bet this thing would absolutely rip with an 18".

I mainly bought the 620p over the 590 for the extra pro features, the support from Echo in pulling a 27" bar, and of course the extra power. With that said I bet running a 590 at the homestead over the 620p would be just as productive. I'm looking forward to enjoying the slightly better durability of the 620p over the 590, but I alway's drooled over the 590 prior to my recent research and continue to brag about it to friends looking for new saws.

Base gasket delete, limiter tab delete and MM that biatch...... then you will see some power. That series of saw responds very well to that list of mods.

 

[Banshee365]

Well, I put the new 620p in some wood today. On an unloaded WOT rev it sure sounds like it has a rev limiter. Everywhere I have read say's the 620p has an unlimited coil while the 590 and 600p's have rev limiters. I thought to myself surely the saw doesn't 4-stroke unloaded out of the box. That's contrary to how I have heard new saws are tuned out of the box these day's. I pulled the H cap and trimmed the tabs anyway. I didn't trim the low yet as it responds off the bottom really great. After tuning the saw to few blips of 4-stroking about 2 seconds apart while cutting I ended up with the H needle about 1/4 turn out from where it was in the box. I may even richen another 1/16-1/8 or so for break-in. I'm running Red Armor 50:1. I don't know if I am on the 'Run your mix at 40:1, it's better for the engine' train. I have ran 150-200cc air cooled RC airplane engines on Amsoil at 100:1 for a decade and a half and they get incredibly long service life. I've never had one score, it's alway's a bearing or seal going out to cause a rebuild. I understand that an engine flying over 100mph get's a bit better cooling than a saw motor but the different between 50:1 and 100:1 is huge. If it were the old day's then 50:1 would be a bit thin, but the premium oils like HP Ultra+ and Red Armor are so good that 50:1 seems more than sufficient to me. If I'm wrong, please educate me as I'm alway's up for learning something that I didn't know. I'm not afraid of that.

I'm very impressed with the power of this saw so far. I am a little hesitant just yet do delete the base gasket and mod the muffler. The exhaust is loud enough as it is (and I'm used to CS-355T with an open muffler), but I'll keep it in mind.

Congrats! I don't have any evidence myself for 50:1 vs 40:1 but run 40:1 just for piece of mind. Always ran 32:1 in our still weedeaters growing up so I guess it just makes me feel better. If you want to try it easy way to make the little bottles work for 40:1 is only use 0.8 gallons of gas instead of a full gallon per bottle.

I would love to find some more info on the rev limiter situation. I'm not sure that I feel like leaning the needle with the trigger held full to see if I can get it to scream on a 2-stroke, at least just yet.

 

[Big Block]

You will make more power on 40:1. It seals the rings better leading to about 10 PSI more compression. That's the same as dumping the base gasket.

I had 185-195psi on 40:1 at an .018 squish on my 590.

I didn't think the 590 was to loud till after I had it ported now I wear ear plugs when I run it.

Just pulling the 90 out of the deflector makes a performance difference and really doesn't raise the exhaust noise level.

600 and 620 should be unlimited coil. 590 is limited at 13,500 I think. My ported 590 still won't go that high so I don't see it as a problem. I'd have to go kill the saw lean to touch the limiter.

 

[Big Block]

That was at 5000 feet above sea level too.

Then get it ported.

Hell ya! Ported saws are amazing. Once you have one ported you want them all ported!
