FWIW went out and helped a buddy clean up his property, lots of cedars and pines to clear/limb. Tach says I did it for an .8 hours straight on a full tank (still have a splash left)... used the 20" bar and handled very well, really like the full wrap as you can throw it around countless ways (like the Stihl 3/4 wrap)

Help Support Arborist Forum:
They don't need anything other then MAYBE a muffler mod. But seriously all OEW parts are available and I have 6-7 sprockets sitting around, both 7 and 8 tooth that fit these things. They are the most common size, look them up on almost any parts site... The 620 is def a force to be reckoned with on the 60cc saw class and even then some with larger bars. Welcome to the site

The 5oop is doing well considering it was spinning at 17000+ rpm's when it was really cold this winter. I really had to richen it up.

Yes I did had a hell of a time getting it started considering how lean it was. Must have been tuned when it was 100 out and humid. No worrie sthough its made in Japan should last me forever.

Becoming more difficult to communicate on this site with all the "Bad Gateway" and "Server Not Available" errors.

Yep, appreciate the reply. Some really good stuff you are posting.
Question: Your tach is reading 13900+ but the manual states WOT @12600-13200. I assume you were able to get that reading without defeating the limiter tabs since you are pretty much running stock? The limiter tabs let you adjust to that RPM?
Still impresses me how well your saw pulls that 27" bar in stock form. You know, seems like saw snobs only care about two things: The weight of the saw and the HP/speed. Echo has been bashed as long as I can remember on those two things. Just about everyone agrees they have always produced well built machines but have leaned towards being heavy and slow.
Your thread has backed up what a lot of us have known for years...paper is paper and real world is real world. I believe, early on, Echo focused more on torque and building a quality machine. The disaster for Echo (from a market share stand point) was that they did a horrible job communicating that to the US market. Those that used their saws knew it but a huge number of guys would never give their saws a chance based on speed and weight ratings.
I like to compare this subject to my Dodge Cummins. When you want to move a load and do serious work, torque is king. They make fancy trucks with more HP but I blow by them with ease pulling my 20,000+lb. load going up a 7% grade. The weight of a saw is a legitimate consideration but I care more about how the saw performs in the cut (where it matters).
So I think the WOT RPM being higher is from the factors of 1. being broken in, so able to run leaner then out of the box; 2. muffler modded so able to breathe better/flow more air; 3. being within 500 ft of Sea Level; and 4. just getting a solid saw?! lol
But really I have not adjusted or even needed to pull the tabs on this last one as the deal understands that these saws do go from SL to 3,500 ASL so the need to tune is important. I agree that throttle response and torque are two things that these Echos have over the competition (cc for cc) and then some. Don't get me wrong I love my ported Huskys but it says something when the 620 with a 27" bar would be my 1 saw plan if that's what it came to... Weight, I can see that being more or less relevant on what you are doing with the saw, but think its humorous that people will go buy the lightest saw just to save ounces then throw the cheapest/heaviest bar on they can find. Do I think Oregon is the greatest? No, but bar wise they are fairly priced, work well and easy to find.

Yes Reed, I have been looking for a clean example of their clamshell design with an aluminum case. Based on this saws condition, I would say it was straight gassed out of the box. Still had raw gas(no oil) in the primer bulb. Compression guage registered 48psi when I got the saw.

LOL, I was going to say...the scoring on that piston is not Echo's fault.

Wouldn't you need to richen it up a bit after opening the muff?
MAybe I failed to mention these things in order...
Ran the saw for a few tanks out of the box, allowing me to lean them out, them muffler modding allowing me to ritchen back up. My Echo dealer is good about where he "sets" the caps so shy of porting it I have all the carb "play room" I need. Clear as mud?!
You mean you can't run straight gas? What if its really good straight gas

One other thing I forgot to mention was just how well these 620's clear when noodling. I noticed in one of your vids (BGE541) that your 371 was struggling with this.
Plus to add to WHT Idaho said, most saw snobs would never believe anything sold at a box store could be of any quality. That being said I did not buy my 600p from said box store, couldn't get it w/24" bar so bought it from a dealer.
