The coil isn't limiting you in the cut. It is not necessary to spend money in this area. It is not necessary to change the carb either. The problem is in the semi-fixed jetting. Replace the nozzle assembly with part # 86-578-1. $4 part will allow you to actually lean this saw out. Gut the muffler. Delete the gasket and you'll end up with around .024-25 squish. Widen the exhaust port, raise slightly, and polish it up. You'll have a much stronger running saw than is shown here for $4.00 and a couple hours time.
Just made the carb, coil and muffler mods you show: Now I have awesome performance in my old 590! with a 24" bar with power to spare!! Thanks so much! Great video and instructional advice!!
This is Great! My 590 is two years old, but I've only recently been using it heavily. Suddenly, it's seems to be running better, and starting easier. I guess it finally broke in. For $300 dollars I paid for a new saw on Ebay. I couldn't be happier. It has good vibration cushioning, and I'm literally ripping beams out of white pine to use as a bridge, and cutting sugar maple for firewood. And I used to use sthil 440 for work. So easy to work on, but I haven't had to do anything to it.
Yeah, they take a longer time to break in, but start leaning out nice once they do - and pick up a lot of chain speed, but still keep the torque. He keeps talking muffler mod, but as I recall mine was an open can, and didn't need much of opening up, and was super easy to do. No welding or splitting required. I'd say just running that saw for a year, it would pick up a lot. I can't wait to see it ported though!!! Bet it will run awesome!
LOL, @09:31 “The Hand Dino...”. I Love it! Awesome! This Man is extraordinary in his abilities and knowledge, and his communicativeness, juss sayin’. 👍✌😊
You mad scientist! That is the best Video yet. We knew the port job would be done by you at start of show. If I didn’t have a Mac 10-10 and a XL 12 to get ported I would grab a Echo and follow along. Here’s a super thanks to you!
10% gain for bolt-on parts is pretty amazing actually. The muffler may be holding it back a bit in this configuration but will be holding it back a bunch once you open up the transfers and raise the exhaust port. That's my guess anyhow. I think you will have a very nice, lightweight farm & ranch saw when you are done. Great video TinMan! Thanks
This will definitely make a interesting build. Was curious as to what the bore and stroke is so I looked the specs up. The bore I figured was on the small side at 45mm the stroke on the other hand is a bit longer then I expected it to be at 37.2mm this thing should sing in the wood after raising the exhaust roof, intake port, and transfers. If a guy can even get his port tool in at it lol. Definitely looking forward to the porting videos on this saw.
I have had a few of these saws and will say they are so easy to work on. Also they have a bypass jet that will not let you lean them. You can order another non bypass jet and push it out , then push in another jet then lean it out. I used to have the part number for the carb part but you might find it out there.
Someone needs to start turning out muffler mods for these popular echo saws. The only one I've been able to find was for my 2511T and it made a HUGE different.
Great comparison video Tinman!!! You’ll be very impressed with the Echo internals…very clean porting and finish!! You’ll be able to do a gasket delete and then some.. lotta head space. Your gunna have fun with this one!!!
Great vid, thanks for taking the time to put it together. I was thinking about getting a new 620 and having it hot rodded. Maybe I’ll save the cash buying a 590 and do some if it myself. Thanks again!
I ve had a ported 590. That thing was a beast. Don't know what my buddy exactly did, but the compression was very very high. But I would never buy a 590 again because if the saw get stuck and you pull a little to hard (yeah yea, I know you should not do this but it reality, you try to give it a gentle pull), the rubber airintake thing gets a rip. This is why the 620 have a limiter strap their. So if you do it - do it with it 620SX. Or just cut firewood from a staple where the saw cant get stuck. I'm sure I have a video from my ported 590 with a 620SX coil and the 620 carburetor on the 590. It make a different that you will feel. I ve to say that I live in Germany. So the 590 and 620 are not so fare away from pricing.
Well done informative vid and not too long because time well spent w no horseing beatin roun the bush talkin bout mama and them just useful worthile info Youd be a wealthy man if you could introduce swirl in the fuel/air mix if mix going thru crankcase 1st didnt matter . Makes easily noticeable improvement in torque w 4strokes and throttle response
Great advice on this saw I got a deal on it but normally a husky guy and noticed this echo had no rpm compared to husky so I will definitely do these upgrades thanks 🙏
New to the channel and love it. I recently purchased a 590 and after breaking it in felling some small trees and helping a friend out with some good sized firewood (he for some reason thought a small cheap ass electric Kobalt from Lowes was enough) I'm very happy with the saw. Seriously considering a new carb/coil and maybe a muffler mod just because. Keep pumping out the great videos.
I normally learn from your videos. What I learned from this one is that I made the best choice buying the CS620PW over the CS490 and at a cost difference of $200. The 620 is more saw with more power and longer 27" bar. It's entry pro and magnesium, too.
awesome. hot rodding at it's finest. i've always admired the slide rule types, but i feel that intuition is of equal importance. I'd love to see whats inside that muffler and hope you do another test, muffler modded before port work. thanks for taking your time, i always look forward to your vids.
Its the check valve that is the bypass or auto enricher which is limiting the tune. There is a smaller valve available walbro 86-578-1 or you can jb weld the little hole.
Tinman's I have this saw. Anyway I would like to see you using some type of hardwood. Not some pine or whatever you were using.. Good video. Honestly I don't think it is worth the cost for my requirements. Great saw for the monies.
@@SuperJamster1 A cheap Poulin could cut through that.. He needs something like a 10-12 oak, maple to get a true measurement out of the saws potential. This demonstration doesn't prove much.
@@kenskip1 We are actually looking at the tach readings, so the resistance is there and should give us a true measurement. Why? Because he's doing the same test with the same wood, i.e. resistance remains constant. I agree a harder piece of wood would be better but looking at his landscape, I'd say he's in the northern midwest, canada line, and that terrain only has a few decent hardwoods. No maple, just it's cousin, box elder. Green ash would be the hardest wood in that area except siberian/chinese invasive elm. (How do I know,well I was a Ranger for 27 years).
Thats good to know,except mine won't start.I bought a new 590 and took it back to home depot,got another one,brought it home,and it started,yay! Then,4 days later,would'nt start,seems to flood easy,but do like the tip!
another great video tinman, thanks. any chance you could do another video along the lines of this one but doing a muffler mod, then (if it is a case/cyl construction saw) a base gasket delete before you port it. thanks.
Been 90sum here, hot, sunny bright day...rained its ass off...talk about humid..past 2 days for that matter apparently a hurricane went bye off shore of me
@@hickerbilly345 he has videos on the first and second version of the filter. The second version was a lot better but still had some down falls. I was wanting to go that route on my 620 but he thought a person is better off sticking with the stock filter
@@jeschreindl I haven't bought one yet mainly because I have like 20 saws but the stock filter was pulling dust in from all around and the center of the filter. I used some slimy permatex aircraft sealant they never dries to keep the stuff out
The reason i thought warranty had something to do with it is my PAS/SRM225 trimmer is sprayijg oil out of exhaust and its a common issue. I dont know how to fix it. Incontacted them and they said "needs to run at full rpm alot". So ill try that but i ran it gull bire yesterday and sprayed a ton of oil lol.
U need try a efco 6510 just picked one up man its nice probably keep up with your 562 was $619 after tax not bad for 63.4 ish cc saw 4 7 hp. So far stock it awesome just got it yesterday so ya got little but time of breaking it in
I have a cs590 that's not even broke in yet. I'd be interested in seeing what just putting the 620 coil on it stock carb would do. . . Red screws fall out of a lot of carbs round here.
Detonating a bit under load. Plug could be a bit to hot? Or spark timing is off a bit. Would be interesting to see what for port timing the Echo saws have VS a similar sized Stihl or Husky cylinder.

You're correct! I've tried to reach out to Tinman and he is impossible to get a response from.
Tx Red any videos or details going over these mods you talk about?
Ok tex you know your game help us echo men out with some info please 🙏
Ya Texas red how about a video
Texas red give the echo warriors a tutorial showing us plz
Torque, torque, torque. Better than speed. I like mine just as it is.
yeah, I just bought one for $200 and im not touching anything, keeping it bone stock.

Run th Fuck outa it. !
I've got a 620 and its awesome. Pulls a 24 inch bar like a beast.
You are right on about how easy it is to work on Echo Saws.
Tin man gotta get that muffler mod before we port it I'll bet it makes a huge difference

Well ! Waiting for the next mod .. Thx for doing this saw, can’t wait

Thanks Tinman I like your comparison videos. 👍
Can't wait to see when you get it ported brother.

If you increase air intake you should always free up the exhaust More air in more air out.

Believe it or not we get the same heat and humidity up here.
I'm curious to see how the echo turns out. Buckin had your Homelite out today , love that saw .
Great content very informative cheers Tinman 👍🏻
Awesome awesome videos that you do and yes this is worth it, thanks.
That's a great simple mod!
Great video! Thanks for the info !
yer a damn good technician and teacher!!! THanks!!
Really would be nice if you would leave the place you sourced the parts like other channels do.
That's awesome Tinman lots of those echos running around here in my area . Enjoyed the watch the tach on the go 😎🤘

I can tell it doesn’t scream but it does have a lot of bottom end torque. Without any money do.
Echo’s run HUGE squish! Have measured 70-80 thousandths on the CS590/600/620 platforms, best mod is base gasket delete with case sealer bond.
Wow
Looking to get one early next year. I believe that, and my 351 will have a lot covered.
It would be interesting to see the original carb and coil with a muffler mod and then all 3 upgrades.
Have the same saw, will be following. Thanks!
Spray yerself in the chest! Very important! Lol. This ones good, Tinman, got a couple of the 590s in my family.
Great video and explanation!
Awesome stuff, thanks tinman
Great vid Tinman. Great results with the changes.

Nice vid brother, thanks for the level no hype approach. Got to love that EZ tach? I think it is the best diagnostics tool I have ever owned.

Happy friday steve
Detonating a bit under load. Plug could be a bit to hot? Or spark timing is off a bit. Would be interesting to see what for port timing the Echo saws have VS a similar sized Stihl or Husky cylinder.
The coil shouldn’t matter in the cut since it’s below the rev limit
Thought if they were semi fixed they had a small hole in the main nozzle on the diaphragm side. Mine does not
I just wished mi e would start all the time when I needed.
How about adding a bottle of nitrous?
