Geez that guy can talk 😂

Some people have commented on how he can talk. I'm absolutely grateful for this guy. He's talkin to the camera guy like he would be teaching his kid. He explained absolutely everything one needs to know about setting it up, porting, desired numbers. I've watched 50 videos from other porting channels and everybody seems to guard their secrets like it's a pile of gold. I personally have a machine shop and I've built and timed quite a few 4 stroke car engines. So none of this flies over my head, but there are a lot of nuances that only someone that does these all the time will know, and he's sharing it. I'm not wanting to build race saws, I just want to build some good reliable work saws that perform well and I don't have to worry about them blowing up. Excellent video. If I could give it 10 thumbs up, I would!

One of the 6 people who really appreciate seeing the wheel of mystery in action. You hit all the high points of what's important. I really wasn't expecting to see so much solid info in 1 video.

best hour and sixteen minutes of KZfaq I've watched this year....cheers

This was not at all boring bro! Great workmanship and a wealth of knowledge.

I always love watching a true professional at work! (Just like you Jacob!) That we got to do it with John’s explanations was a great bonus and very generous of him. Only 3hrs! Give us 3 more!!! Thanks guys.

Best porting video ive ever watched and ive watched them all. I port saws daily from work saws to race saws and i very much enjoyed this vid. Thank you and your friend for taking the time to make this . 👍👍

I LOVED THIS VIDEO! There's nothing better than watching a craftsman at work. Thank Jake and John for letting us watch the process. I'm definitely one of the 6. 😁

Jacob broke us in with an 8 hour saw idle 😢 This is light speed. 😅

I've done 4 Stoke motor cycle head's for years and we all have our favorite bit's.When they clog or go dull it's part of the oh no moment. Love w.d.40 for clearing chips and final finish. Always wanted to look over someone's shoulder on a 2 stroke. He was very clear on the dos and don't and why. Also love the foot pedal to adjust rpm and quick change handle. You both rock this video and thanks!!

I’ve recently started porting saws for fun and videos like this really really help with all the little things. Nice one guys 👍🏻

As a climber we all know the ms 200t is a legend and still the best climbing saw ever created but this one here that you guys just built is so awesome! Ty for sharing that! Shout out also to August that bar is awesome!I have a new respect for Guys like John and Bellhopper that build cause that’s a talent in itself! This is the best all around tree service channel on the web! You guys rock I loved this video ty for that!🍀🪓🇮🇪as always keep a handle on it!

Dude! Just seeing this and it’s freaking great… I was climbing the the 80’s and 90’s and was a poor WV kid with my homelite and Mac’s and my first real boss got me my 015 and 020 and 026 …. Now at 53 it’s building saw’s and flopping over and busting up the bigger ones… awesome sauce!!!! …. I’m super stoked that one of my favorite modern climber-dudes who I really like to catch his videos!!! “tube-guy’s” is going to have a fantastic saw from one of my favorite tube-builder’s!”… the “Cocky young buck!!!” I love how he drives other builder’s to …”shut it!”!!! LMFFAO’!!! This is fantastic!!!! Love both of you guys channels and work!!!!

these three vids are easily your best ever uploads for me personally love it and massive respect to John for allowing it 👌

Thank you so much for sharing this, and filming and editing! I learned more from this video than anything I've seen on youtube. And, such a nice job too! I hope John shares more, especially on the newer strato saws.

I have watched a lot of porting videos, but this was the best, I have been wanting to port my 201tc and this was what I needed.

Best video on porting on the whole inter-webs! Love the very exact mixture between raw experience and hard cooked numbers.

Cheers!!! Pretty amazing to have John willing to allow you to film and post. Appreciate all the tech info and the attention to detail!

I just started to get into gas powered chain saws since a friend bought a new Stihl.He taught me so much in a short time that now I want to know more .Thank you for your spirit and desire to pursuehaving the best tools avaliable and the best team menbers to make the day go by stress-free .Great video .2 stroke engines were never a part of my experience as a youngen. Today I learned a lot .

That was awesome! Long, sure but needed because of the details. John does a great job of explaining the why as well as the what. That really helps better understand how porting improves performance. A good follow-up to this type of video would be a tour of how Stihl makes the top end. The science in that process would probably make this video look like a walk in the park. Great video Jacob! Keep'm coming.

I am one of the 6 he was talking about. Haha At the machine shop I worked at we had a flow bench for porting heads. The reason you want dimples on the intake is the air is being pulled in and by having the dimpled surface it actually does the opposite of what you would think. It allows the air to glide across the surface as it is pulled through the port. It smooths out the disturbances from symmetrical differences in the port by having the negative space below the high points. You can kinda think of it like a shock in a car. But also having less surface area the air actually touches as it is pulled through the port. So less drag it has while it is moving giving more flow/air to the cylinder. In higher end performance cars they do the same to the under belly of the car to reduce drag. The reason the exhaust port is polished is because the air needs to be forced out as quickly as possible it does not have time to let velocity help aid the removal. Having dimples on the back side would actually temporarily slow the exhaust gas coming out not allowing all of the waste to be expelled quick enough before port or valve closes. We are talking na machines here. I have never tested a rough surface on exhaust port while running a turbo charger. They have back some back pressure that comes along with them. May aid velocity to give its benefits of quicker than a polished port. Key word may... Have never heard of anyone running simulations on a flow bench to test the possibility for added benefits. Butt would not apply here. Thanks again. I will need to watch this another 4 times this week to absorb all the things. ;)

I won't be doing this myself and STILL FASCINATING. Watched the entire film, so cool to watch a professional. You never realize how specialized your work is until you have to explain to someone else!

Gonna put dozens of hours into porting a saw so that I can speed up my firewood efforts by 3 minutes LOL. Great video, really goes to show how a lifetime of learning can make something so complicated look so easy.

An amazing education... Its always great to see Great American's passing on their trade/craft. Definitely not boring... Always enjoy!

Brilliant! John is an absolute legend 👏🏼 awesome work

13:34 That measuring instrument is a digital caliper, not a micrometer. Great job. A huge amount of info & knowledge being shared here. Thank you.

I've been working on cars and trucks most of my 40 years but I only recently got into two strokes during covid ...... In that time I acquired 8 chainsaws and one was an 088 that needed a cylinder. I bought a new cylinder and piston which was the new style muffler so I welded up a two-stroke muffler from a dirt bike from a video I saw I also Port matched the exhaust port to the muffler and did a little bit of porting in the cylinder from another video I saw but I wish I had found your videos first. Thank you for the information you share, it's cool that you pass it on the way the gentleman who taught you did.

Thanks for showing porting on a small saw awsome to see. I am definitely one of the 6 people that got alot out of it nice job!

wow that process is amazing! I have heard of porting and polishing with autos, never knew how complicated it all is! woderful skills and knowledge! thank you so much!

Nice job bringing out the heart of a teacher in John in these video's. 👍

Great video, and thanks for the memories. I'm 72, and my Dad's machine shop was my day care. I was running a Clausing 13" lathe by the time I was 8 years old. I retired and sold the building two years ago, the new owner had no clue of what to do with the machine shop. The lathe sold for $500, $300 for the Bridgeport mill. Eight 30-yard dumpsters of metal and tooling went down the road. I'm still crying.

Really cool video, thanks to John for sharing some of his secrets

Very impressive!!! It's great watching a professional at work.

Fantastic video thank you both for taking the time to make this happen there's a lot of very greatfull people watching this absolutely brilliant so much detail 😎👍

Thank you John and Jake for making this video. John, you’re a master of your trade!

I work on construction equipment for a living and that is way more complex than what I do. My hats off to you and thanks for showing me I don’t want to try to hop up my own saw.

Great video. Absolutely pro level work. I love porting saws

Wow, how very generous! THANK YOU for sharing this knowledge with the world!

Yeah man…. That’s a hot set of numbers straight up…some polishing and flow and it’s ripping! Great video Johneey Appleseed… you’re doing a fantastic job of explaining about how saw’s run and what they need and how you are trying to help it and how you aren’t hurting it… my man… this is one of your very best videos!

Awesome video Boy’s!!! You guy’s should be proud of this… every young guy who wants to port should watch this!!!!

Just amazing, Bless you for sharing your wisdom with the world.

This has been an awesome series. Some much useful info. Thanks Jacob and John!

Jacob and John, great vid. As a home saw modder I have zero problems with anything said here. As a logger, I love ported saw. And at the end of the day to guys like me it all that matters is that I can cut 100 plus’s trees a day and the beast keeps on going. Thanks for putting this out there and maybe we’ll bump into each other in the woods someday.

I’m an architect by trade. My brain doesn’t work like this. This is so impressive to me. Thank you! I will never port a saw but it’s always good to watch skilled craftsmen!

I doubt I'll ever get a ported saw. I know for sure I will never port one myself. I hardly understand most of what John was saying or doing, though I was tracking pretty good. I absolutely enjoyed the video though. I figured a ported saw just had a few mods on it. I had no idea it was that thorough of an operation. Aside from great education, it is such a privilege to watch a professional do his craft. Great job.

can deck the cylinder with valve grinding paste and a sheet of glass (std. float glass is super flat).... Great video and really informative. love the sound effects with your dog is snoring in the background

WOW!!! Dont know why John would think any of this video was boring ?? I was fascinated !!! So much so ive subbed to his channel !! Aw the best fae Scotland

This is the most useful porting video's on youtube, PLEASE MAKE MORE!!!

Awesome video. Learnt even more! This guy and Tinman are awesome. Thanks for sharing the wisdom! Wish I'd seen this before I ported my first saw as a hobbyist recently. It worked really well but this would've been great.

Very eye opening what go's into porting a saw. Can't wait for the next one.

Your the man bro, I'm definitely one of those 6 people who really got something out of this video. Very good job, you are talented! I really wish I could come port a few things with you. Keep up the great work!

This is an exceptional instruction video! Very informative. Thank you

You guys are rock stars. I'm dreaming of racing out all of my saws now!

Another awesome video. I always get excited to see a video of yours go live. Nothing like watching a master at work. The length of the video doesn't matter when the content is that good.

Knowledge is definitely power in this case. Thanks for sharing it.

Watched the whole thing. It was jam packed with information and experience

I'm glad I watched all of it just for the prize... Thanks to you and John for all the knowledge

Sweet video. So much knowledge being shared, thank you.

Glad to see your new channel succeeding. You deserve it.

Shoutout to the ladybug hitching a ride on John's neck.

Great tip thanks. Having owned LC4 KTM 4strokes in the past, loctite quickly becomes your friend! Got a new 395 myself recently, off to the shed to do this right now.

I'm one of those 6 people grateful for the information provided 🙏. Just picked up a 200t to build my own limb reaper 😈

Wow; had no idea it was that scientific, and also so much by experience. Great tutorial and video work. Have to say, just like Jacob, I didn't really understand much beyond the first step of raising the compression; that I did understand. Love to see the side by side test of the 200T's !

I did watch it all ,glad your having fun again Jacob !!!

I appreciate this video. This is something I'm super interested in right now. I've got several saws I wanna try this out on.

Awesome. A pro with passion and knowledge for what he does. Just like someone else on this channel.

I have 10 OEM stock Ms200T saws that i built,, have enough parts to build them on hand, nice video, nice to see the porting i build stock only, Thanks Lewis

enjoyed it buddy!!!! Thanks for sharing his knowledge!!!

I actually sat through the whole thing! Very informative. Just wish we could see assembly and some use. At least we got the special prize at the end!!

I have a bunch of old 020 saws from that time era Love the Dog snoring in the back ground sound !

Nice pet ladybug... thanks for sharing

Really awesome video. It's cool too see a guy share his knowledge on porting not to many guys do that. And it's even better to see a saw built that is going to be working not reving 15000 rpm with no torque.

Love his explaining. very thorough, without like taking all day. liked the info on the lave. I would love him to work on my saw, if I was in your country. He sure knows what he is doing.

Thank you for the information the 200 t I have 3 that came across that are all not working so the rebuild info was great thanks so much

1:04:30, now I understand who I heard snoring earlier in the video :) Was already checking on my own cats.

Amazing! Gotta get my saws to John!

Loved this oneJohn, really helpful. Thank You

Pretty technical. Thank you for the lesson.

These type of videos have a worth not measurable. Sharing detailed knowledge is vital to humans relation and growth. Cheers fellows!

Super Cool ....intake roughness...square out ports... Polish technics on exhaust... Fine grindings are abrasive and dont wipe off well in my anion.....I take distilled water with dawn dish soap and boil head an vigorously srcub with stiff plastic brushs to get all the fine grindings out and boil in clean distilled water...blow dry and spray head down with wd-40....Im a amateur..5 years silver Stihl Tech. Thanks Again , Great Video 😎

This was probably the most interesting hour and 16 minutes of the day

Theres a Big difference from truck engine heads and chainsaw heads... Gr8 vid thank you for showing your viewers a how to on this chainsaw!!! GOD Bless😇😁

I absolutely love this video. So much knowledge. And skill wish it was longer I can’t wait to see the next video!!! TGBTG

Like you said. Very few will watch and learn. I will never probably port a chainsaw. I rarely even use one. But seeing you and watching the knowledge and passion I decided to stay and learn anyway. Props to u bud

Got my first 200t today ill be using this as a guide soon

Good info my friends and great job ,and thank you both for sharing what you have because it has helped me out alot.now I'm going to tear down my 200t and rebuilding it.but I'm not porting mine,just new seals and and lines.

All I can say is that what I watched tonight was awesome! I learned a lot.

Thanks guys! that was brilliant, Master saw man!

This was very informative thank you. I'm going to attempt this for the first time lol

excellent video that’s one I could watch over and over

No interest in doing this myself. Just love watching all you guys get together. John’s absolutely right, Instagram is a different breed and has a great community on it.

Would definitely recommend a DRO for the lathe, it makes such a difference 👌

Awesome process, the explaining and the filming view is perfect. Made me want to try and do it on a ms210. wish me luck

Forget the surgeons, if I ever need heart surgery I'm calling John!!! 😂 So much information, if I ever do a saw I'll be watching this video and taking pages of notes. Thanks 👍👍👍👍👍

Awesome channel Jake, great and very informative videos as always. Didn’t realise how much went into ported saws😱😱😀, Thank you John👍👍 I hope Inbred Jed is doing great and all your previous mates from Eastside? Good luck with this channel and your new venture. Take care. Jonny

great video & great explanation from John

I have really enjoyed these detailed series good stuff as always I’d watch it everyday if could haha take care

CHEERS JACOB AND JOHN from UK ,really helpful l !📸✊🤘 Thanks for taking the time to do that

More Gordy please that dude is a legend😎

Love the video a true master of his craft👍
