I have a echo cs590 that I purchased from Mitch Weber. He also ports saws n such He did a 15minute fluff job on the inside and increased the venturi size in the carb. And I believe the coil mod I’m not even kidding one bit... that echo 590. Outcuts BOTH of my holzfforma g372xp. And riiiight there with my g660 (92cc) 20” bar you can bury it in the wood I put a 28” on it and it STILL pulls chain like a mofo!
Thanks tinman learning so much from you very grateful with my 272xp I'm going to do a muffler mod I done one on a 36 I was amazed at how much power it has just from doing that. Stay safe
He’s basically cutting that cylinder into a 365-372 type feed design... it’s got me wondering if it’s a pretty direct swap to just drop on a Hyway 52mm 372 kit??? Might be a scary 266
Tinman, I’m so happy to watch your Chanel. I think of it as “Our” Chanel. It is what I look forward to every week. Thanks for being an honest saw builder. I absolutely can’t wait to watch you build buckins big homelite. I have no doubt that you will make it rip like your last Buckin homelite. Keep up the great content. Fan for life bud.
Just found your channel while looking for tutorials on how to port my 266xp and I have to say that I really like your videos. Very informative and entertaining stuff. Could watch you all day long! Keep it up
I have built two saws after watching your "how to port" series videos. Both Holzfforma/Hutzl kit saws. A Husqvarna 372, and a Stihl 361. Both saws run awesome. They both pull 24 inch bar/chain with good torque and seem to have great chain speed. Thanks again for sharing the info!! Look forward to your vids.
Well I just stumbled across your video on port timing (cutaway) and it was very thorough, easy to understand and got me to look at more of your vids. Well all I can say is we are birds of a feather! Love those older saws and artifacts! I’m just like you with brands, I enjoy them all but do have my favs. In particular the 70’s era Huskys & Stihls. I must say tho I’m jealous of your Mac! Hey I noticed an old Stihl next to that 590, it that an old 08? it’s great to be onboard and subscribed! Keep up the great work. Cheers 👍
Fun project. I use piston stops for finding TDC if I do not have a dial indicator handy. I too have been using rope for a piston stop for torquing clutches and flywheels since forever. I have not damaged anything yet. But there is still time.... :)
I owned a couple of 266s and I thought they were dogs though they were stock. Naturally progressed to the 268 and upward but noticing a lot of these 266's have seemed to really take to a porting job very well.
Good vid and info I thought of cutting up the bottom of that cylinder but had to wait to see what ya were going to do , can't wait to see the rest of this series 👍👍
Love the content. Can’t wait to see how things play out. I have a similar build on the go and I’m concentrating on increasing the bottom end compression.
I am so excited to see what this 266 is going to do!!! Sounds like a pretty bad ass combination of parts!! My 565 is going out west soon and I’m very excited about that as well. Awesome video bud. As always WORK SAFE 😎😎
hey tinman ,henry im from bellingham ma . im retired and been doing small engines for while. and just got into saws this pass year being quarantine. im into husqvarna. i ve been watching your channel and a couple others. thank for your info . stay healthy
I'm ready to see what you do with that 590 just bought one a few weeks ago this is my second saw my first was a ms 391 that got stolen a month after buying it so been watching your how to port a saw series going to map it tommorow and go fairly mild about 2 or 3 degrees just use it for firewood a couple times a month keep up the great work bud!
If I'm tearing down a saw, gonna be changing the piston and cylinder anyways, I go for the impact that I have and it zips off easily. Even if the piston and cylinder is still good, I go for the impact because it's just honestly easier for me instead of putting rope down the cylinder. I just keep the plug in the cylinder and the pressure stops the piston movement.
I usually blend the opening of the lower back to the bottom of the barrel, more in the interest of keeping up velocity and keeping a smooth flow. However some saws benefit from being ground completley into a bottom fed transfer. Thats what Jonsered did on the 910's and 930's, 920's were side fed on the same cases. The other two outperform it greatly... Have you looked at the difference in compression height on the 372 vs 272 pistons yet?
Heck. I been running saws for about 20years now There’s some things I can work on and fix. But I have a big bore kit for my holzfforma g372xp I’ve never done one. So I’m going to pay a local to do it and I’ll watch. So next time I can do it myself
Just put some new SKF bearings in a 371 fella said they were rated at 22,000 rpm box says made in Italy, Crankshaft in the freezer and it fell in hot bearings
Tinman! Love the videos man! Been watching for a while now. Currently bidding on a 266 locally. I want to get it ported and have a solid saw. How can I get a hold of the iron horse or someone to port it for me? Thanks buddy much love from Ohio!❤️
So what you’re saying is the using a park bench as a spoiler on the trunk lid of my fwd car isn’t doing anything for me. Shucks. Haha in all seriousness love learning on this channel.
Wait,I have a car with a park bench spoiler, unfortunately,my in-laws are always setting on said bench, it won't go anywhere with em on it...🤣😂🤣😂good stuff here ain't it brutha....💚🌳💚🌳💚🌳👍👊
Man I´m soooo excited to see what you are doing with it! I timed my 266XP over Easter and I´m a little curious about my blowdon. It seems veeeeery long. I measured 38°... Nevertheless I will re-watch your timing videos and figure out if I´m wrong. And I ordered new SKF-bearings because I decided ti rip the saw apart completely. Go on brother!!! :-) Greeting from nothern germany.
@@tinmanssaws I figured out my fault... MY timing wheel shows 4x90° and not 2x180°. So I measured 82° which is in real 102° ATDC. And my transfers open at 120°. That fits...! All that after base gasket delete. Now I have to find out what I can do to not fullfil the impullse hole without the gasket...
I am really looking forward to watching this one come together. Is there any way the crank can be disassembled and the big end bearing uprated too? I imagine it is now the weakest link bearing wise. Will you roll the bottom edge of the flat sides of the piston to help the flow to the transfers? Would there be any potential gain in squaring the case out where your new open transfers are? Thanks.
I cut a fair amount of firewood with a Husky 450 and more recently an eBay upgrade -- a lightly used Stihl 460. My son found and gave me an older McCulloch Power Mac 6. It starts and runs, but roughly. Cute little saw. Is it worth sending somewhere for a thorough service and/or restoration?
For tin man. It is possible to make windows. It is best to smooth everything on the underside of the piston. The edges that Ironhorse talks about stress risers you can cut more into the bottom of the piston not to close to the wrist pin spots but a bit around them raising the bottoms of the pistons at the transfers allowing the fuel mix and air to move smoother reducing unnecessary turbulence. It is a gain not much of a gain. I have learned with harbor freight predator 212 engines and them having to basically be all stock internals with a small .750 O.D. tech ruel exhaust pipe with the mini b91 rlv muffler and certain size holes in both the baffles. That every little thing internally these steel and touched steel or aluminum needs to be mirror polish finish from the bottom end to the valve train after doing so you gain around 1/10 to 3/10ths a hp. And racing in a circle and having to have that roll speed on a stock engine not turning past 5200rpm that extra 1/10 to 3/10ths a hp does help more then you would think. So me being me I polish the wrist pin and rod bearing wrist pin bearing race for the oil to have a smoother surface for more even oiling as well. I personally haven't had a failure from not to say a cheap bearing is a cheap bearing.
Cool. Thats what I was asking about when you were doing the Echo build, cutting away the skirt of the cylinder for increased transfer flow. Do you think you would loose any torque at all doing that with the slight increase in case volume? Cheers mate.
Hey TinBasher...is the new piston open above the pin in that little recessed area? And you are making a little transfer passage to get back that loss???
I’m so lazy! I’m just drinking my giant coffee and thinking he’s going to grind a 365 or 372 cylinder... I’ve got a couple cheap 48mm 365 cylinder!s I wonder how the direct swap saw would actually perform.... loved the carb comparison story! I’ve found that just finding it’s balance and harmony ...intake and exhaust duration adjustments and sometimes those little things can totally boost performance... is a fingerport a fingerport if it actually resembles a clamshell or a toe??? LMFFAO! I get to thinking boy I wish I had a dyno... because my higher quality piston design might actually restrict performance??? About Brand Loyalty...ain’t nothing funnier for me than having a Stihl piston in my Husky or Vice Versa ... I love parts swapping across different brands... 😂😂😂
I really like the idea of cutting out the sides. Ive pondered doing that on a 2100CD. She should rip. You going to turn the base down and recut the combustion chamber/squish band on this one?
Just wondering if you have ever tryed finger port and if you have what your opion on them. I see them being done on some of the facebook groups thay i follow.
Hey Tinman, get my number from Harvey and give me a call if you have a chance. There are two drastically different ways to run our 272 CCC Racing piston.
With the skills you have why is this channel turning in to the fix the Billy Ray saw show, people love your vids for who you are not who you know. Sorry for the negativity I might be wrong again sorry
Best Tinman Quote “I move air for a living”
Going to follow your videos and so looking forward to seeing and hearing the final finished powersaw. I'm admiring your knowledge and skills.

You definitely have your own style and just love the outcome! Great job Tinman!
Gonna be an awesome rippin saw. Can’t wait to see you and buckin run it👍🏼
Hi Tinman, thanks for the update I'm looking fwd to watching you do your weird and funky stuff and seeing the outcome.
Thats gonna be wicked!!! Love the channel
its going to be intresting to follow this build.like every build
Tinman! Thank you again for the knowledge. So cool to follow along and get an education. 💪
Looks like it's going to be a beast! I like it. Take care tinman
This is very interesting and promises to be a grouse build.
Thanks Tinman 👊
I can’t wait to see this build. I’m very excited about hybrid bearings.
Great work 💪🏻🪓⚡️💚👊

I hope so, its got the right parts to be silly!!
Plug in and use a little Milwaukee impact to take the clutches off
Same way ive always done it

you should try to put a cylinder from a small dirtbike engine on the saw. a think its possible,lots of work but what a grazy power saw then.

Not only does it cause problems with the piston but with the wrist pin needle bering flat spotting it if you arent careful

New subscriber please forgive my ignorance. But where and how does one get a saw ported.
Why are the windows in pistons, of saws that use transfers beginning under the exhaust?
Cool. Thats what I was asking about when you were doing the Echo build, cutting away the skirt of the cylinder for increased transfer flow. Do you think you would loose any torque at all doing that with the slight increase in case volume? Cheers mate.
Na it should help me build power in the saws power band
Is there an reed set going to join the party on this bad boy?

How much surface on the mating face (flange) of the cylinder is required to seal it?
I really like the idea of cutting out the sides. Ive pondered doing that on a 2100CD. She should rip. You going to turn the base down and recut the combustion chamber/squish band on this one?
Just the base on this one.
A powerful chainsaw motor 2-stroke would be good on a bicycle those Chinese or do they 60cc could you adopt the motors
Where abouts in Ontario are you?
Just wondering if you have ever tryed finger port and if you have what your opion on them. I see them being done on some of the facebook groups thay i follow.
Finger ports can be used with great success if you have a way to feed them.
