Can't wait to see that 590 in the wood, I've appreciated you keeping it real throughout the whole build, the ups and downs of getting to learn together is what it's all about!

Tinmam, i went against my better judgement and bought a 2017 model used CS-590 from a pawn shop that looked very used and the bar and chain that was on it was worthless so i had to buy that as well. In all i have about $260 into the saw. I also have a CS-400 that seemed to run better and cut faster than this 590. I took the 590 apart just to see what kind of condition the cylinder head, piston, rings etc was with no intentions of porting. I thought why not just try porting it a little whilr watching your videos. The only thing i had was the little diamond cut fittings like you used for the fine blending at the bottom of the port. So obviously my grinding was going to take forever without going to harbor freight. Anyway, so i decided just to very slightly port it and angle the transfers. I didnt grind nearly as much off as you because i dont have near the experience with chainsaws as you do. I didnt expect to be able to tell any difference in performance. I also deleted the gasket between the case and cylinder head and used Moto Seal or whatever you recommended(that i did goto the store to get). I also opened up my muffler exactly like you did but not as much. Then i assembled and cranked her right up... all i can say is wow. Totally different chainsaw. Revs wayyyy higher and cuts wayyyyy faster. Im blown away!

It's actually pretty great u took this build on. Their's tons of these out there and always nice to see how different it is from builder to builder on them. 👍

Man I have been lurking here for a while, and thought I would drop a comment. You have excellent content and I hope you never quit creating like this.

Way to hang in there Tinman! We learned a bunch from you on this one. Congrats! Now to cut some wood.

I know very little about the inner workings of a power saw but after watching your series, I feel like a genius!

There are few things better than when you finally sokve a saw problem. RIGHT ON!

True friends share both the ups and downs... tenacity level 10 👍 thanks for powering through this build. I’m glad it worked out 💪

The 590 project back on the table. Great to see it again

can't wait to see it in the wood.

Phew, that was a head scratcher. Well done.

Exciting build! As many have said before, it is really neat to see how you showed every step of the way, even the things that didn't work out as well as you wanted. Way to go! 💪💪💪

Glad to see it appears to be fixed, hope you can put it in some wood soon!

Oh boy.. that little bugger sounds and looks real snotty 👍👍. Nice work, buddy. Great of you to stick with it and trouble shoot your work.

Aye great to see this running again and sounds better. I can't wait for it to be barred up and cutting 👌

Grear job on the cs590, been patiently waiting to see success.

Really sounds good, amazing how you figured it out

Glad to see that 590 back going!! Great job buddy!! It’s sounds mean that’s for sure!!! Take care and have a great weekend!

Nice job man ! Good to see you finaly got it going

You got er Tinman. Awesome. Enjoyed the build!

That 590 sounds awesome!!!

Sounds good, I think you nailed it. Can’t wait to see it in the wood.

Great job on sticking with it and figuring it out! Your videos are really helping me to learn these saws.

So good to hear that 590 sounding happy again😃 after you went back and raised the upper transfers, I had a gut feeling that was the solution. Hopefully she rips in the wood now🤞 after experiencing the gain an Ironhorse style pipe made over the modded stock muffler on my CS-590, I'd like to see a pipe tested on it! On mine, I used 1.25" OD & 1" OD both 18ga wall. Thought it'd be too big for 60cc. Thanks for sharing!!

She sounds nice and crisp throttle response great job Tinman

MMMMMM! snappy. Good job Tinman.

Nice work bubby, good to see it going, a lot work, great to hear it running like it should be.

Awesome job

That sounds good nice crackle to it. Let's see it in the cut.

Nice. You found the flow!🤙

Thanks for continuing with the build. I've learned a lot and I am doing your suggested strap on mods and muffler mod. I'll stay away from trying to port though!

That crackle at idle sounds great

Thanks for putting this up Tinman. Just saw you in Wooly’s livestream. My 590 has been great thus far. Still stock, might open up the exhaust after 10 tanks.

Hey Tinman, well looks like persistence won this battle. Good job. We all learned a bunch. Thanks for another good vid!

Hope it's good in the wood. I admire your grit to stay with it. Interesting to watch your thought process as you overcome problems. Thanks for your channel!

Awesome channel

That’s gonna be a very nice firewood saw👍😎

Nice work Tinman! Upper transfers 👍No JB Weld 👍 Sounds and restarts great! Looking forward to seeing it cut some wood. Glad you stayed with it.

Sweet!! Looks like you got’r figured out bud!!

Sounds great Tinman. You saved it...

Tinman, Nice to see that 590 running. Been looking at porting my cs600p but had been waiting to see how this turns out. Thanks for keeping at it and all the knowledge your sharing.

I was able to get a little bit of fire wood cut and split. I’m trying to get my garage cleaned up so I can get my Land Rover Discovery back up and going. I hope the weather breaks for you soon bud. Thanks for keeping the content coming. I don’t have the patience or the skills to get the camera going while I do my tinkering, you’re doing great 👍.

I never had any doubt.

you can do it! I have faith in ya!

I have a 590 that just quit running after about a year and a half of med/light use. I found your vids while I was trying to find a solution. Love it. I think I will swap out the impulse line like you did and see what happens. It looked okay when I inspected it so we shall see.

Thank you!!

Sounds much better.

That's one happy Tinman right there! ✌️

I've been pushing the timing numbers on a Husky 350 Chinese cylinder out of sheer boredom. Finally decided to just run the OEM jug with intake timing bumped up to 78 and leave the exhaust alone. Thanks for getting back to this saw

Can't wait to see it in the wood. I just got a 268xp. I might have to put a grinder on it. God knows you have enough content on those saws.

Happy u figured it out sir some saws will drive u crazy!!!

Hell yea brother. I've bein cutting and swingin an axe on some firewood this week mostly. Got a new piston and cylinder for my 066 red-light to put on then take off and port lol I always like to see how a saw runs stock before I port it. Just one of those things.

We used to call it “case burping “ back in the 1970’s when we were trying to get International Trials bush bikes to have lots of bottom end torque with good rev build to dig quickly when needed . I had a Yamaha , I think it took 2 or three cylinders to get it right , it was a 460cc single and was killer good in the Bush ride on the east slope of the Rockies in Northern Alberta we used to ride into BC , helicopter fuel drops the big 490 huskies we used to say they turned gasoline into noise !

Morning TinMan hope all is well with you staying warm as well.

this is late in the time line but having just watched this video I feel so good for you...the thrill of winning a long wrestling match! Learning has a price, you paid and will profit handsomely. Power saw college! Thinking about this,the trouble did not start until after a few heat cycles probably because the rings set in and you got a much stronger vacuum creating way more venturi draw. The add on carb from a bigger saw did not help, it just dumped more and more fuel than the saw could handle. You guys do this stuff by the seat of your pants, it is an art. You have no air flow and sophisticated engineering aids to assist...just your thought processes and observations. Hats off to ya for excellent problem solving. The small primary transfer ports now we can understand....they limit the strong induction designed into the saw until heavy power demand is made.

Wow, great channel! I am glad i came across it when researching my 590 Timberwolf. I am going to do the muffler mod as you did. Is it worth adding the new 620 coil with the stock carb or is the carb upgrade required? I plan on running a 28" skip tooth for cutting cookies to make table tops with the 20" as the primary cutting bar. Keep up the great work. Your channel is on the rise because of your positive no BS attitude that always makes catching one of your videos feel like you just had a beer with an old friend. Be safe!

Hello Tinman, my husband Kevin loves watching you he thinks you give great advice!! He works on saw's too but he's more a Sthil man!

Well if ur right about all that theory then that's straight impressive. Ty for great vid.

Good job Tin Man!! Be on the look out though. My 590 & 620pw are headed to you….😂

Sounds great. Look forward to seeing it cut.

I can not believe you fixed that pig CS-590 Tinman. Awesome job. Tried last spring, runed poorly super rich out of the box would not lean out, but despite the countless videos talking how "great that CS590 saw is" - liars. [actually though of calling the EPA]. This Your modded one sounds happy. I know you spent a year working on it - very good job.

I'm lookin forward to when i'll get to see how that echo runs with a 24 finally

Looks like it blows back through the carb a bit still. Sounds not bad

2 pieces of plywod 1ft by 2.5ft, bungee cord and eye bolts for foot bindings should work.

COOL!

I want to see you go snowshoeing!!!

The intake needs tuning. Either a smaller intake port or less intake timing. Blowdown shouldn't really change it unless the charge is having trouble getting through the transfers and not scavenging the case. If you have to reduce your blowdown, then your transfers need to be bigger so they can scavenge the case.

Are you gonna make another video showing what the saw can do now?

I’ve been learning to make planks out of old growth yellow cedar free hand

I see you had to put the decomp valve back in. I looked but couldn’t find plugs that fit the Echo cylinders. I ended up using a oil drain plug from a Honda GX200. Had to cut it down on a lathe but it works great. It’s a 10X1.25 thread instead of the more common 10X1.0 used on Stihl and Husqvarna.

That sounds way better, well done. Was it the porting or the carb mod ? Any chance to run one of the other carbs that didn't work before to answer this question ?

Do you have any follow up on this saw? I’d like to see it run! I’ve built a snappy nasty 590 and I left the upper transfers alone 🤷‍♂️

How did you get the rubber boot from the carb to the intake off ? Can you show more of the tear down next time please .

Love the 590 but still seem to keep going back to my 272 husqvarna, guess I'm not a true new saw guy !

Having trouble snowshoeing? You need larger shoes, for a heavy person the longer the better. Some snow is just impossible wait for conditions to change. Today l was walking around all over no snowshoes the snow is rock hard

At the beginning of this video you mentioned you opened the transfer sooner but there was never actually footage of your work inside the head for the second grind… loved this series but just wanted to mention the discrepancy and also ask if you actually have the footage to add?

Good stuff. Sounds narly. It's going to cut like meat loaf.... bad out of hell... Mahalo Tinman 🤙🤙🤙...Tdawg.

i use a very small paint brush to apply RTV it is alot more accurate applying it

I have the echo 590 and a Jonsered 2260 Can I put the bar on the echo from the Jonsered 2260

Do we get to see it in the cut?

Snappy!

Did you ever get the 590 figured out. I just watched the whole playlist and it was like when your favorite tv series gets canceled, there was no ending.

590 ported

How does it do in wood?

So how did it run in the wood

Why not more exhaust a modded muffler an extra port to get the gasses out?

Levels of tight: Snug Tight Tight tight. Gorilla Tight. "Holy sh#t!"

👍👍👍

Being a HD guy, I’m surprised you don’t use hylomar, it is ready to use immediately.

Never a doubt! Get it barred up and in some wood!

Hey tinman, would LOVE to see you just for fun use your porting skills on a cheap weed eater and walk us through it. I think plenty of guys are afraid to risk messing up a good saw by attempting to port it, but string trimmers are about the cheapest gas engines you can find used anywhere. Can regularly pick them up on fb marketplace or off the side of the road for free, so would be awesome to get some practice and learn the concepts a bit on those before trying on a saw

Tinman how do I know if I have fixed high jet on my carb….Stihl 084

Did the echo run good after this?

It sounds like you fixed the echo cs 590.

Did your decomp plug not work I see you got a decomp in it the thread is m10x1.25 not 10x1.0 like huskies and stihls. I got one in mine I just used a Allen head bolt cut it down to the length and put an brake line washer on it. Just thought I'd let you know

TIn man, what happened??? Is she good to go, does she rip???

I need to replace the piston and maybe the cylinder on my CS620P. I would imagine the process should be very close as I watch you put the 590 back together. Am I correct? Thanks in advance.

That’s Caleb’s 590???

Sounded really zippy to me runs great.

Try out some cheap military surplus snow shoes and go from there.
