This guy is definitely a tradesman/machinist/engineer. This goes beyond maintenance and if a guy like him was on every street corner the retail business would suffer.
Finally the proper bandage for the finger. Being a retired electrician 3M 33 was always my bandaid, it’s medicinal! Seriously, thanks for sharing this info and taking the time to video, always appreciated! BTW your expression with the wind was priceless glad you left it in.
"Give me a few minutes and/or an hour!" I love it. You know how many times a day I could use that??? Love watching you work on this saw that so many people can have access to! 👍
I love how one clip there's sparrows talking and a second later there's crickets chirping. Nice video, helps theory crafting port numbers for novice porters. Keep up the good work.
Done a base gasket delete and many muffler mods but never any porting on 2 strokes. Rebuilt a couple Chevrolet 350's and now I've got the itch to learn how to make more power with my saws. Thanks for sharing this with us Tinman!
I have finally caught up on your Echo 670 "How to port" series and its great general knowlege. But the CS-590 is how I found your channel. Have had one of these since early June that I bought to help our local scout camp cleanup after a major windstorm. I really like the saw and plan to build mine right along with you. Just hope I have better uses than more storm cleanup in the future!!!
Nice video. Echo saws aren’t overly popular, so it’s nice to see one being worked over. Time for the underdog to show its stuff in price to performance ratio.
A very good video. And I will add I checked the cylinder mounting bolts and the front right side was loose. However you did not mention how loud the saw was after the muffler mod. I drilled two 3/8ths holes in mine at the same spot as you and yes this made it louder. Other wise it is still stock. When it cools down outside I will let is stretch it's legs.
I was hoping this teardown would show how to teardown this saw. I have to teardown my CS590 because the top hose on the carb needs to be connected to the barb fitting inside the case, but it can only be reached if I completely disassemble my saw.
Echo build a great saw hell product for that im building my old John deere 80ev which is a rebranded echo 750evl 78.6cc right now. Young bucks don't dig em but I like a workout while cutting wood 💪 saves a gym membership tbt
Another great vid, looks like a thread starting to strip on the muffler bolt hole. Maybe factory over tightened but forgot the cylinder bolt torque haha
Tinman wondering have you ever been into a 2083 turbo jonsered.. that is my all around magic stick I owned two in past ported quiet a few for customers after lending them my personal one to use while I repaired there saw . Every one I trusted enough to let them take mine owns a 2071 threw 2088 now.. I try and buy every one I find and good luck finding a bar cover for one in one piece lol. Tbt the port timing is great stock they also are a pioneer brand saw ;a beast in the cut ... I like your channel I been a buckin sub for about 3 yrs now . I been porting saws and fixing for certain people for years only ..most my saw running is firewood these days. I have lay down some wood in Florida especially after hurricanes . And a bunch of home wreckers. Keep your peepers open for a 2071threw 2088 if you ever find any and don't pick for yourself keep me in mind there very hard to find here in maine
So excited for this build, depending on price diffrence with carb and ignition vs the 620 and then port the 620...idk I'm tickeled to see this baby, I love rpm but I luuuuuuv torque in a saw..mad torque
I can't seem to get the rubber air intake that's connected to the engine to release from the carb area. Looks like it's press fit in a round hole. I took the limiter screw out that you mentioned, this rubber piece is all I need to remove the engine from the body. Nvm, got it. A small metal round piece holds it in from the carb side.
Use a thin brown paper gasket with loctite 515 for your cyl gasket. Equalize your transfers and aim them up the back wall. Widen the exhaust. Use the 620 carb and the 600p ignition coil has the best advance curve.
Hello, I was wondering if you do chainsaw work? Porting? I have the Echo 590 and would love to have it pepped up a bit. Do you do this kind of work or any recommendations? Thanks man! Ty
I would think 104 will be nice and torquey for a long bar. 102 would also work i would imagine if ya can keep the compression. I would think this would be quite the saw with a pop-up. I wonder if theres much to gain widening that exhaust port, after all you will have good blowdown. But it also seems a little narrow and the less pressure in the cylinder when your transfers open the better. Definitely don't think it would hurt. I'm excited to see how the build turns out. Also those are some unique looking transfers, it will be cool to see what you do with those.
Looking great dude!!! Absolutely love your new camera setup! Looking very much more professional and shop like with your chosen setup and background... “straight from Borat...”Very Nice!!!” LMFFAO!!! The 590’s for a new 60cc firewood or work saw at $499 and the 620P at $550... What you have in front of you now... because it’s not a 590 with the coil and carburetor additions ... it’s really up to the 620P after you raise the exhaust roof... those parts and a little higher exhaust roof to increase their RPM and run more “professionally”... are the main difference’s in the two saw’s... echo basically added more timing to retard the 590’s performance... like Husqvarna added the baffling on the 365 xtorq to restrict some performance and still be able to use the same parts across the two models...which is great for a guy who has a little bit of confidence and who will grind his new cylinder. The timing wheel is just critical for a guy to get comfortable with so he’s comfortable with knowing how his engine is working and can change it for the better. I highly recommend that guys also do the little bit of additional work and actually use a port mapping page and draw out the numbers or transfer their numbers onto a port mapping page.., so that they can visually see how their particular engine is working. Kensie From Bayou County PowerSaw’s has a good video showing his port mapping pages.., it really helps me to actually do the paper 3D to 2D visual reference so I can see where my upper transfers are actually fitting into my stroke... helps to see how to balance my stroke. As you can actually count the difference between the “events” and see the timing on paper... and it’s not just a mental process and metal figuring... it’s visually right out there in front of you... I was trying to add it here but I can’t insert a picture...? I have it if you want it.,,if you send your email...? 👍😁. Love what you are doing to help teach everyone saw building and it’s such a great video reference... I can send someone with a question over to see a great how to video...that you have made! It’s definitely handy for a lazy guy!!! LMFFAO!!! Love ya man! Keep up the great work... Harvey broke the ice and paved the way with the actual sharing of the numbers and took lots of flack... but Kensie from Bayou County backed him up and old Hopper did too!!! It was Buckin Billy Ray’s work and pushing to try and get this information out on RUclips to get guys the real information. Now the guys have you have you!!! .... and you have really made a difference!!! Your videos are put together wonderfully as a teaching tool. “ You make the videos that you wanted to see or how you would and could actually learn from...” this is just wonderful content for young guys wanting to learn porting and experienced guys to get a reference for the saw’s that you have done on video... I loved how excited old Harvey was when he was saying get over to this guy “TinMan’s” channel... he’s actually made a cutaway saw so a guy can actually see how those transfer ports actually work in a chainsaw engine!!! It’s really great how you guys are really sharing and teaching guys the real deal and getting the real meat and potato’s of saw building out there!!!! It’s definitely been great to watch how much the available information has increased over these past 10-12 years. Absolutely love your channel, buddy!!! I’m going to enjoy watching your channel grow up to the 100k subs group of channel’s... just keep doing what you’re doing and more and more people will continue to find your wonderfully informative channel!
Watched hoping to get the skinny on how to separate the tank and "block" sections. I'm trapped by the springy thingy on the bottom of the saw. Must that spring be removed from the boss that it's on? Does it have a screw holding it on? How to get it out of the way so I can get that pin out of the socket opposite of it?
Hello Tin, Hope you're the right guy to answer my question. I'm relatively new to doing own repair on chainsaws. I have this cs-590 and simply wanting to replace the old cylinder with a new one that I just got. Is this a pretty straightforward procedure of only taking out old cylinder and popping in the new one or I'd have to figure the math behind the timing as you would when porting? I'm again, only replacing old with new. Many thanks! :)
I wonder what the squish would be if it were to be checked in line with the wrist pin. I’ve always heard that checking squish anywhere else can cause the rocking of the piston at tdc to throw the readings off. Not sure how much truth to this there is. May be a neat video idear.
There is too much springy over travel on them A V springs and that long screw goes in a big hole to limit it. I have filled mine, there's one front bottom across from the AV spring with a plastic nub in a big hole. I make silicone bushings for mine because I don't like the over travel .
Good question. I recommend visiting the channel and got to "Playlists" and watch the How to Port a Chainsaw series. Very good videos even using a cutaway saw to show 2 stoke operation.
Hey Friends!! Question: anyone know someone in the USA that does good work on saws? Got one of these 590s and would love to have someone per her up a bit. Any advice would be appreciated! I am in Montana.
This guy is definitely a tradesman/machinist/engineer. This goes beyond maintenance and if a guy like him was on every street corner the retail business would suffer.

I love it. You know how many times a day I could use that??? Love watching you work on this saw that so many people can have access to! 👍
Everything I came to watch on this channel is the part that’s preceded by “give me a few minutes and I’ll be back”.
I love how one clip there's sparrows talking and a second later there's crickets chirping.
Nice video, helps theory crafting port numbers for novice porters. Keep up the good work.
Done a base gasket delete and many muffler mods but never any porting on 2 strokes. Rebuilt a couple Chevrolet 350's and now I've got the itch to learn how to make more power with my saws. Thanks for sharing this with us Tinman!
It all started from red light to red light for me too . Porting 2stroke differant from looking at lift an duration cl ect charts for camshafts

Looking forward to the final product. I have a CS 590 and it’s interesting what you can do them. Thanks Tinman
I am so friggin excited for this. Had a 590 for a while and love it can’t wait to turn it into a lightweight work saw.
Great video! I’m doing the carb, ignition and muffler mods to mine as well. Thanks for diving into this build!
I will be following this build, was in the market for a 590, bought the Stihl ms271 instead, no regrets there, but I just might get one of these too
And another exciting chapter in the Echo fitted for its destiny in dried wood saga
Good seeing ya buddy! Curious to see what happens with that jewel!👍👍👍👍🇺🇸🇺🇸🇺🇸🇺🇸🙏🙏🙏🙏
Htown represent! My cs 590 giving me fits. Gonna try this. Ty
Ahhh Yes. I quite like the echo saws.
Thanks for the echo videos. I like my echos 😊
Great video
Hey Donny, never seen you porting XTorq strato Saws? Will there be a Video in Future? Maybe 545 or 550 Husky?
I live in Houston and the BBQ is about the only thing that keeps me here.
Nice video. Echo saws aren’t overly popular, so it’s nice to see one being worked over. Time for the underdog to show its stuff in price to performance ratio.
Quality shoutout👍🏻 Brisco builds some solid saws.
I'm late, hey buddy...died last night after work..good morning video
Morning
You're the best chainsaw man on RUclips
electrical tape band aid 👍tinman. I sling garage doors for a living . Always keep a roll in pocket
Tin Man your awesome! Thank you for all the knowledge.

Real interesting series. I have had a CS-590 for a couple years now. I like it but wouldn't mind if I could get it to be faster.
Awesome video! Very interesting seeing this saw tore down. Lol
Hey Tinman, could you please make a video of you putting a cylinder in the lathe and correcting the squish?
Great video. Thanks Tinman 😎🤘
Use a thin brown paper gasket with loctite 515 for your cyl gasket. Equalize your transfers and aim them up the back wall. Widen the exhaust. Use the 620 carb and the 600p ignition coil has the best advance curve.

I use autozone brake cleaner on the base gasket softens the glue up an makes taken it off much easier with a razor blade

Proud to say I own one😎👍

I have a echo cs 400 series and I absolutely love it but I would love to get my paws on a cs 590
Great video!
Echoes, particularly them 590's are a dime a dozen where I'm at
Hello Tin,
Hope you're the right guy to answer my question.
I'm relatively new to doing own repair on chainsaws. I have this cs-590 and simply wanting to replace the old cylinder with a new one that I just got. Is this a pretty straightforward procedure of only taking out old cylinder and popping in the new one or I'd have to figure the math behind the timing as you would when porting? I'm again, only replacing old with new.
Many thanks!
:)
Morning, just pop off the old cylinder and piston and install the new one and your good to go.
thread RHS on intake start to pull
I thought the exhaust was 112 when you checked it before? Anyways thank you Tinman.
I wonder what the squish would be if it were to be checked in line with the wrist pin. I’ve always heard that checking squish anywhere else can cause the rocking of the piston at tdc to throw the readings off. Not sure how much truth to this there is. May be a neat video idear.
I hear that to.
If the piston is rocking that bad fore and aft then I'd be inclined to say the piston is warn out.
There is too much springy over travel on them A V springs and that long screw goes in a big hole to limit it. I have filled mine, there's one front bottom across from the AV spring with a plastic nub in a big hole. I make silicone bushings for mine because I don't like the over travel .
Nice hat
Thank you!!
Great series lol. Trying for now to avoid the other playlists so I don't buy them all and mod them all lol
That saw should rip when your done 😎
Tinman, how do i go about getting a saw ported by yourself?? Im wanting either my 372xp or 395xp done...
Thanks
What is the limiter screw for?
Wonder if 620 has same stock numbers as 590?
So how would a base delete run without porting? What’s the gain. Compression?
FYI TMAN I found the cylinder bolts torque to 65 inch pounds ..
Sorry for the newbie question, but is that solder that you are using to test the squish?
Good question. I recommend visiting the channel and got to "Playlists" and watch the How to Port a Chainsaw series. Very good videos even using a cutaway saw to show 2 stoke operation.
Longer stroke=bigger circumference=longer dwell
I wonder what the theory is behind the style of transfers on that Echo.
Sometimes a saw will run better with transfers that open 1 degree apart.
@@tinmanssaws Okay, thanks. I figured they had a reason 😉
We’re the isolation springs rubber or metal on this saw ??
They are springs
Hey Friends!! Question: anyone know someone in the USA that does good work on saws? Got one of these 590s and would love to have someone per her up a bit. Any advice would be appreciated! I am in Montana.
Hey tinman are you gonna delete that compression button on top?
Is that solder??
Where’s all the go juice tinman hehe
K. So. I like to think I know a bit about saws... but can’t figure out what that limiter screw does🤦♂️Anybody?
It limits the AV mounts travel
Hey right on Tinman! Thanks for sharing. Lol. That was really hurting my brain. Now I wonder if it’s just an echo thing?
That squish band is ridicolously small
Maybe that why echo thought they needed a low exhaust roof.
🤖man, I don’t know whats easier to understand: Your degree wheel numbers or women…🪓🪵🪓🪵🪓🪵🪓
