As mentioned before, with having to restrict flow to meet government regs, it's understandable that they have to build the mufflers the way they do to pass inspection.... That being said, it would be super nice if they would put a knockout plug (like a metal electrical box) to make it quick and easy for the end user to get the designed performance out of the saw 😁
As nice as that would be, the government doesn’t want you to modify anything for better performance, as the excuse of emissions/ and or safety, so manufacturers leave this opportunity alone for the end user, and a lit of these mods will void warranty! The cs590 has a five year warranty! So when I mod mine, it will be done on a second muffler!😂
This is a great series on the 590. I bought a 590 a couple of years ago and just did a muffler mod to it right away and found out that it was a major hold back of power. I like the results so much that I ended up selling my Stihl MS360 and keeping the little echo. Keep up the good info sharing 🤙
@@Tatted_gunna I did something very similar to what Tinman has done. Cut open the exit hole and then I went in with a drill bit to punch a bunch of holes in the baffling. It has been awhile but I think that was what I did to open up the muffler on the 590.
hey my friend great video !!! just an FYI, when putting your burr into your foredom or dremil . push the shank all the way in . then just pull it an 1/8 of an inch out and then tighten it . this will prevent bending the shaft as it did, or even breaking it. just a little tip that was pointed out to me by fellow wood carvers ,that helped me out a lot . love your vidios man , keep on sharing your knowledge and what you do !
I had to go to the non-bypass main jet just to get it to 2 stroke at 8 thousand feet. I have a 620p and a 600p plus I rebuilt two 590s. Did the carb jet replacement on all of them. I also found with stock porting at altitude, it really lost torque if I tuned it for high rpm. They like to be a bit rich. Echo makes a nice saw. I love that almost all of the screws are the same and you can pull the carb in about 2 minutes. Snug the screws only, no cranking them down or they will strip out. Parts are expensive as well, a negative. Bar sizes are goofy stock too.
Throttle response seems to be snappy! Never owned echo anything, but I’ve heard that they have come a long way from what they used to be! Loving the build series brother. Thanks for taking us along fir the ride
Really,echo has always made quality products. Now,with their chainsaws people are starting to realize you get a lot of saw for the money. Their saws are getting better and better though. I used to run nothing but Stihl trimmers now it’s all Echo.
Haven't had a tank ran through my cs590 and already sent it to Iowa Performance Saws for a muffler mod and tune removing the limiters and getting it back Tuesday, I can't wait for it to get here to see how it runs now
I just did a bunch of work to my echo thank you for the content tinman helped alot I gotta say my 620 p far better then the 562 now it is a torgue monster now base delete ported muffler mod and stoekel stack air filter and it's a dream now
Same way I do them. Tip on your grinder if you're using it hung right there you're gonna burn cables up. Hang it from the ceiling. Took me about 5 cables to learn that 😂
Really like how you chose to do the muffler mod as it keeps the spark arrestor in use. Like the new camera view set-up as well. Once ported this 590 will definitely out-perform a stock 562. I noticed you didn't show or mention blowing/washing out the metal shavings from the modded muffler. Pretty much a given for the experienced, not so much for a newbie. Love this series on the 590. Huge Echo fan myself... 501P and 620P in my stable.
Perfect for video it seemed to be easier for you than having to move in closer and check for being in frame! With all the regulations manufacturers have to comply with restricted mufflers are to be expected. I agree wholeheartedly with porting and getting more fuel in will obviously cause more heat and it needs more space to exit. Looking forward to this build. I’m especially interested in where the high jet ends up afterwards. I’m guessing a turn and an eighth. Thanks for taking the time to video this.
I just played with the dremmel today. Opened up some holes in the muffler for my poulan farm hand 295. 🤪 What a difference. It's simple. Air is lazy. I'm a tool and die maker by trade. I had my fair share of porting and cleaning heads for the car scene.
What I had done with mine was cut open a small spot on the bottom of it, that allowed us to get inside and totally gut the internals, then closed it up. Then welded the existing outlet on the top closed, and then drilled two holes off each corner 3/4 inch and brazed 2 3/4 inch pipes. Looks like a dual port husky muffler now. And it flows now and my 620 absolutely rips., I did what you did first, just drilled out that area and I felt I lost too much bottom end. Too little back pressure. But it still ran good. But not nearly as good as this. The other option Tinman is to weld the existing outlet up, then drill and tap the deflector off the front. Of the muffler. And gut the internals.
I hogged mine out quite a bit more aggressively, and I washed it out with soap and water befor running it as it had alot of shavings trapped in it I didn't want going back into the motor
It sounds like that carb likes to fuel. Thats a beautiful thing considering she's gonna eat more of it when you open up those lower transfers and get her turning a few grand more on the rippems!
I really enjoy your 590 videos, I've been working one professionally now coming up on 5 years (semi-retired tree surgeon on a budget) and beaten the heck out of it over the years, it works wood 3 and 4 times the size its designed for. Never tried to mod it, just run the 24 bar on it and kept it stock but going to give the mod a try. BTW, you asked about the new camera angle, I can't see what you're doing most of the time because its facing you so everything you're doing is blocked by what you're working on. Just fyi. Thanks again for doing these 590 videos, they're great.
Also glad to hear you mention atomization an swirl . You would make money if you found a universal way of introducing swirl to carb venturi or immediately after for chainsaws
Just recently bought a cs590 Timberwolf and before breaking it in I sent it to Iowa Performance Saws for a muffler mod and a tune. Can't wait to get it back next week
I just started modding my 590, watched all your videos about the saw. My first mod was swapping out that semi fixed high jet, coupling that with a muffler mod and unlimited coil. I'm going to get it into wood for tuning soon. I'm excited for the results.
Great job bud. Interesting seeing what it did letting it breath. I think all saws are restricted way to much in the muffler. As always WORK SAFE!!!!😎🇨🇦🇺🇸
Trigger respons is great...big improvement...I cut at 8to 10k feet in the rockies...need to find out how to get that deal on my dolmar and husky Grest video!
Oh heck yeah Tinman. I love it. That Muffler is built alot like the one on my 570 husky. That echo is much easier to mod than the husky. That is a sweet mod and a big help. Thank you buddy. Oh yeah great video I love the new bench. Great job. 🌲❤🌲✊🪓
I'm still tuning on my 590 I just ported an I tride a red barn popup but it's a heavy piston I think I wuda Ben better off cuting base an makeing a popup out of my stock piston. At wait to see that one ported
Enjoying this echo journey 😁 dont care for opinions but my humble assessment you present a very good explanation an illustration tutorial and admire that you seem to care that folks actually learn something . Tip my Resistol , Tinman
I freakin love the tuxedo shirt coming out to party!!! With the extra torque you can know drag your file across those rakes 4-5 more times, right? LMFFAO!
Just subscribed. I have a Echo CS-590 for my cottage property. I use it for about 2 weeks of the year, hard, to cut the 4-5 cords of rounds I need (split later) to get me through the winter. Its a great saw. I love it. I do notice that when used that hard, it gets hot, but I just stop working and carry out the rounds while it cools. I'll watch all your CS-590 mods and see if I can get it to work even better.
Good move. I got my cs600 hot buried in some massive wood and wasn't savvy enough to slow down. But on the bright side, I discovered Tinman while I do the cylinder and piston rebuild!😂
And if anyone does and struggles I'm sure I'm not the only one in our saw community to help anyone out, not knowing how to weld basics is a major disservice to urself if u work with metal at all
I wonder where you guys get the 620 coils from. They are between $80-120USD everywhere I've looked. Price difference between the 590 and 620 here is only $160, so it seems that adding a 620 coil and carb to the 590 would be more expensive than just buying a 620.
Awesome to see the progress you have made! been awhile since I've watched but I love to see you working and growing still! you and Billy are the reason I bought 5 old homelites last winter and brought them out of their graves!
The muffler is a major power thief on the 562. There no doubt about it. I honestly couldnt believe how much power it gained. The first time I used it after the muffler mod I was amazed.
Cool and easy mod! With an better cuttingspeed and Sound. I'm also very curious about the effect of the of the timing advance when it is done! Thx Tinman!
Always appreciate you shop talk Tinman! Hey, with that mod is there any concern for short-circuiting from the muffler inlet to outlet? Would you have done anything differently?
If you covered this in another video, I apologize, but why do you pull the recoil before shutting the saw off? I'm a 3 year arborist and was wondering if this is something I should be doing or not, bc I've never seen anyone do that

Great series on these Echos. Nice to see a different saw than just Sthil and Huskies.
It definitely was night and day with my 590. I can’t wait to see the difference when it’s ported
Would have been nice to see muffler mod first, since that is least expensive. Great video.
Was waiting for the sprocket to send that chain plate flying… Glad it didn’t.
Nice new backdrop for the video’s. Change is always sweet especially when you did such a great job Tinman!

What kind of mod did you do? Just curious I just purchased one and it’s rlly restrictive. TIA

I did the same muffler mod on my 590. Between that and pulling the limiter tabs, it turned into a different saw. Love how it sounds as well.
I agree, its very stuffed up from the factory
This is good series 👏. Like wheres its headed

Hey fellow tin knocker did commercial installs and shopwork for 15 yrs in Maine hard work
Great video, this is my favorite series!
Love the Echo CS-590/600/620 platform!
Nice background, A few years you'll have a collection like Bucken. Im enjoying this series. Stay cool!
Can't wait to see the next video. I got the 590, it's bone stock hasn't even had a full tank gas through it yet.
Haven't had a tank ran through my cs590 and already sent it to Iowa Performance Saws for a muffler mod and tune removing the limiters and getting it back Tuesday, I can't wait for it to get here to see how it runs now
I just ordered 1 this morning before I saw you had a series on it...first thing I'm doing is this mod...thanks Tinman!!
Amazing production Tinman. Thank you for sharing with your community.
Pretty impressive. It is going to kick butt, when finished. Nice work, love the new set-up in the shop. Take Care, Stay Safe and Be Kind...
Wow, What a difference. Nice vid.
The set up for filming is much better so we can tell what you are doing.
I just did a bunch of work to my echo thank you for the content tinman helped alot I gotta say my 620 p far better then the 562 now it is a torgue monster now base delete ported muffler mod and stoekel stack air filter and it's a dream now

I have an Echo 590 and love it so far. But I'm looking at moding it up and this series is great to show everything step by step.
Thing sounds alot better too! Think Im gonna get a 620 now!
I purchased 620pw with 24" and a 7310p with a 28" bar.I live the saws.
@@andrewslagle1974 my stable of Echo's is growing also! Have 500vl, cs680, 7310, 501p and soon to be 620 lol
What I had done with mine was cut open a small spot on the bottom of it, that allowed us to get inside and totally gut the internals, then closed it up.

Made it breathe! Made it snappier too!👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏
I like your neatly stacked chainsaw shelf.
Nice video Tinman.
The New setup is great. You should keep that!
It sounds like that carb likes to fuel. Thats a beautiful thing considering she's gonna eat more of it when you open up those lower transfers and get her turning a few grand more on the rippems!
The new setup looks great brother! Thanks for all you do for us newbies love the channel. Have a great weekend.

Thanks again for doing these 590 videos, they're great.
Love the new setup!
I do this to all my 5 series husky’s, reach in under the deflector, hog it out and put the screen back in. Zero welding, works great.
Also glad to hear you mention atomization an swirl . You would make money if you found a universal way of introducing swirl to carb venturi or immediately after for chainsaws

Love your “NEW” look Tinman!!!! Great detail and one can REALLY see what your doing!!! Better for you to be setting also!!!👍👍👍
Looks like a good idea opening up the muffler
I feel better seeing I done mine the same way and it is no doubt stronger. My 330T was not as easy
Good stuff tinman
Less restriction is not always better on 2 stroke engines cause they need back pressure to reach peak power
Oh yeah Friday night in the shop!!!!! Loggin in the mornin gettin my gear ready and hangin with the tinman
Like your new "set" . Had a 2015 model 590 and the muffler was different than that one. Pretty much wide open with just the screen.
Great job bud. Interesting seeing what it did letting it breath. I think all saws are restricted way to much in the muffler. As always WORK SAFE!!!!😎🇨🇦🇺🇸
You said it is too dry there? Yeah we definately don’t have that problem in Mississippi right now!
Trigger respons is great...big improvement...I cut at 8to 10k feet in the rockies...need to find out how to get that deal on my dolmar and husky
Grest video!
A hole saw works awesome to take the pipe out. Sounds like a 80cc dirt bike
Those discs are impressive! You're like a human miter saw!
Seems to me the order of these mods you did for anyone considering them on their own saw would be:
1) muffler mod
2) coil upgrade
3) carb upgrade
Oh heck yeah Tinman. I love it. That Muffler is built alot like the one on my 570 husky. That echo is much easier to mod than the husky. That is a sweet mod and a big help. Thank you buddy. Oh yeah great video I love the new bench. Great job. 🌲❤🌲✊🪓

Love these vids bro. Have a new 590 coming in 2 days and digging the thought of increasing its power.

🤔
And if anyone does and struggles I'm sure I'm not the only one in our saw community to help anyone out, not knowing how to weld basics is a major disservice to urself if u work with metal at all
FYI from a tool and die guy, if you use a taper bit it'll reduce vibration
Great to see this series happen. I'm hoping to buy a used 590 to go with my cS-520, and you sir have a new sub from Oshawa.
That’s awesome, especially with the three changes, thanks
Good set up Tinman.. we will get some wee porting Videos like what uncel Harvey does.👍🏼🏴 Mega content today tinman.
Question: Why pull on starter rope when shutting the saw down ???
Maybe 2 ironhorse ramps on the top of the port as well🤫 see how that changes it when you do rough up the intake.
Awesome series on the cs590. Got me thinking about doing a muffler mod
Alright, I gotta get after my Husqvarna 261 muffler 👍
Thank you for this video I'm doing the muffler right now and reviewing this video cuz I trust you not some of these other nut jobs lol thanks again ❤
when you say high jet 1/2 turn .. you mean you tighten it down all the way then back half turn ? is that correct ?
I like your work, but just slow it down a bit bro! Take yer time, keep your stick on the ice, cheers!
Ok, cut with the 562 with those small mods! Thats thing gonna be a blast to see once you port it!!!
Rite! That 590 once ported shld b a lil closer to a stk 562
Love the Echo's great saws, & excellent vids 🇭🇲👍
NICE SETUP BUDDY THE VIEW WAS BETTER SET UP THAT WAY ,,GREAT JOB BUDDY,NICE SHELVES FOR YOUR POWERSAWS TAKER EASY TINMAN
I wonder where you guys get the 620 coils from. They are between $80-120USD everywhere I've looked. Price difference between the 590 and 620 here is only $160, so it seems that adding a 620 coil and carb to the 590 would be more expensive than just buying a 620.
What a sound! Crazy and loud!!!!!
AWESOME §RIES BUDDY GREAT WORK MAN BE SAFE BUDDY
Overall Tinman, how does these echo saws compare to the old school huskies?
Awesome to see the progress you have made! been awhile since I've watched but I love to see you working and growing still! you and Billy are the reason I bought 5 old homelites last winter and brought them out of their graves!
Love the new setup
The muffler is a major power thief on the 562. There no doubt about it. I honestly couldnt believe how much power it gained. The first time I used it after the muffler mod I was amazed.
Be interested in seeing if you picked up much for rpm with the muffler mod.
Cool and easy mod! With an better cuttingspeed and Sound. I'm also very curious about the effect of the of the timing advance when it is done! Thx Tinman!
New stage looks GREAT !!!! Love my 590 just hate it being stock ;(
View is good. Keep up the good work!
Always appreciate you shop talk Tinman!
Hey, with that mod is there any concern for short-circuiting from the muffler inlet to outlet? Would you have done anything differently?
AWESOME video content and yeah series, love you buddy, what buckn say keep on truckn lol
Good angle for viewing, thx!
Awesome mod thanks tinman
I'd like to see you work out where the spark is triggered in deg btdc..
me too ///how you been
Interesting to see some Bolt-on mods. How bout doing a timing advance and running it again before grinding?
Great build so far👍
Be safe and be careful
Great stuff!, as always....
🤝🤝🤝🤝
Will most larger cc saws benefit from a muffler tweak or 2?
If you covered this in another video, I apologize, but why do you pull the recoil before shutting the saw off? I'm a 3 year arborist and was wondering if this is something I should be doing or not, bc I've never seen anyone do that
It saves wear on the starter dawgs on old saws.
Is there any reason to still do this with modern saws? Thanks
Why do you pull the starter cord out when shutting off? Thanks have a stock CS590
Maybe a more breathing air filter would help leaning it out, but I personally will always prefer a rich tuning rather than a lean one
