I like the 038 Mag II with a 28" es light bar for felling (very well built saws), and my 272 with 24" Tsumura light bar for cutting up firewood and TSI work. 038 mag II is a little stronger stock, but I like both saws. That 038 well tuned with good gas/oil will last another 30 years on that cylinder. Great to see this saw being rejuvenated.
I HAD A 038 MAGNUM BACK IN 1997 ITS BEEN A WHILE🤣🤣GREAT SAW NEVER HAD A PROBLEM WITH MINE ,,GREAT EXPLAINATION,,I THINK ID BE ABLE TO USE A DEGREE WHEEL NOW AND PORT MY OWN SAW ,,SEEN MANY OF YOUR VIDEOS AND THE DEGREE WHEEL HAS FINALLY SUNK INTO MY BRAIN 🤣🤣🤣TOOK A WHILE ,IM A HANDS ON GUY LEARN WAY QUICKER THAT WAY ,,THANKS TINMAN BE SAFE BUDDY
Nice Vid!! the first Chainsaw i ported are the 382,the latest version of that saw.Timing are pretty similar,100 ex 74 intake and about 23 blowdown.I put it around 98 exau and 78 intake,they actualy ran pretty good at that number!! They have an open transfer port design! They also have those crank stuffer? mybe like those 661 ect..
apparently the Hyway cylinder looks closer to the stock Stihl than the Farmertec one. Farmertec (with 0,020" base gasket) had 96.5 ex, 68.5 in, 112 tp. this gave 15.5 blow down only, so i've deleted the base gasket and still had to JB Weld the tp roof to come to my target (116 tp, 160 ex, 156 in duration) nice vid!... thanks for sharing such content
Have you seen that Donny walker notches the piston skirt on the intake side? It was on one of Buckin Billy’s videos. It might be something else to play with.
Makes ya wonder what would happen if you just square up a port at opening. It seems it would give you more rapid fill and better evacuate exhaust gasses with a more rapid rise in the "injection of the new fuel/air charge. Might lead to better performance without actually having to change timing
It seems like the Hyway cylinder's profiles for both intake and exhaust were much flatter and wider @ the roof, allowing more flow at "first crack" thru 1° and maybe even sub 1° of additional crank rotation following that "1st ray of light."
Oops. I also wanted to ask if this is what you're seeing and commenting on, as well as to say, this video ROCKS TINMAN! I need to watch it a couple more times and take careful notes to really soak it all in. Send my love to the wife and your baby, too! Woo Hoo! Another Tin-people is on the way! Prayers are with you as you embark on a brave new journey! :)
Tinman ok great vid but with all them numbers what is it that we/You are looking for? What is the sweet spot number? I am looking to get into timing saws but I am missing something here.
Cool video. Can you still get the tank and handle new for these 038 magnum 2 saws? I dropped my saw last year and I broke the handle on the bottom,JB welded it together and put a piece of aluminum to strengthen it but it looks welfare. I got this saw from my uncle after he died,he bought it brand new in the 80s so I want to keep it in good shape,still runs great and it’s a good complement to my sweet 066. Hello from Vancouver island 😎
On intake, excessive duration may lead to poorer performance. as the pressurized charge in the crank case is relieved by the open port, pressure drops rapidly. the last few degrees of open intake at super low pressure doesn't accomplish much in terms of putting a larger, stoichiometric charge into the chamber. On the exhaust side, a low pressure charge finr the intake port can be affected by back pressure pulses from the muffler actually pushing burnt gases back into the chamber or at least stopping the all of the larger charge of new fueal/air from entering the chamber. Just thinking out loud so I could be all wrong. It's just that "scavenging" exhaust systems have been the holy grail of engine builders for a very long time
Is there anyone out there making tuned pipes for chainsaws. One thing I recall form my shop rat days in cycle shops is that lowering back pressure increases top end but robs that from low and mid range grunt. I would think that a saw needs that grunt to keep winding thru a cut. Most of the muffler mods I see would increase flow and reduce back pressure and that may not yield a better cutting saw
;Lookin for advice Tinman, i lookin at a 038 to buy , do ya see a problem with being old havin problems finding parts this not a magnum . any advice would be much appreciated . i enjoy your videos as well Thank You The guy has an Echo 670 too for 100 bucks more than the Stihl , they both run
Yes. The Hyway and FarmerTec cylinders and other parts are constantly undegoing redesigns and updates. They used to be trash but nowadays they’re getting pretty good… in most cases.
Hey tinman! I’m a relatively new subscriber and I have myself a Chinese knockoff of a sthil MS380 and it’s very similar to this saw. I was wondering if you believe that this saw will pull a 30” bar stock?
@@willtrippett6578 It will definitely have its hands full. I wouldn't probably run more than a 24 inch on it. They pull a 24 inch pretty well in the hardest oak trees we have here.
Tin man?? I have an O75AVE AND I RUN IT HARD at least 3 times a week. Yesterday I pulled the pull cord out and it won't go back in. I think maybe a busted spring. Do you have any access to parts for my saw? Lol I really wouldn't mind getting it Tinmanized too. Hee hee
I don't get those intake numbers? If you open that soon, 70 after bottom and close 70 before bottom that would be 220 degrees not 140 degrees? Or what am I missing here?
HI TINMAN that other chainsaw most likely has a over size carb jet they will use alot of gas like that unless that was the way the engine was from the factory replace the carb jet 2 stock or carb U don't want a gas HOG if U can get more air 2 the engine it should do better if U have 2 do more work on the engine U do what U have 2 more power is alot better than a gas HOG any day OMG 2 12 2O23
I’m just about to sell my 038 magnum :( I’m gutted but I have lost my job and have no real reason to keep the old girl anymore:( So if anyone here wants to give me a offer for the old girl or she will be going on eBay.
How do I get your email? I think these chinese saws give home enthusiasts a chance to practice some of your techniques without worrying about screwing up a porting job and ruining a $1000 saw

I ran Stihls starting with a 048 magnum, 056 magnum and an 038 magnum and did all my own maintenance and repairs.
Never ran an 038! Great to see an aftermarket company making such accurate parts!
i have an 038 Super Av, love that saw
I have the same saw as well. Incredible compression, solid heavy German construction.
hi there i am new here //// this is the best vid on ports and how it all works i have ever seen well done
Tinman looking so professional with those balck squared glasses
Good Vid with excellent descriptions of how you are getting your numbers.
Thanks Tinman for teaching us to time and port saws😊
Finally your into the 038 thanks I rebuilt mine last year squish was 45 thou with gasket 25 ish without
We got an 038 mag 2 at work and before we got our 661 we used it with a "25" bar to mill rough pieces for repairs on some of our historic cabins
Thanks for having us! 🙂
Great channel, glad I found you.
I have an 038 mag 2. My absolute favorite saw. Still runs like new. Gobs of power
Nice Vid!! the first Chainsaw i ported are the 382,the latest version of that saw.Timing are pretty similar,100 ex 74 intake and about 23 blowdown.I put it around 98 exau and 78 intake,they actualy ran pretty good at that number!!

Is it just me or is pistons and top ends just beautiful when they are new !
Think about the intake opening and closing at different times...
Nice breakdown Tinman

nice vid!... thanks for sharing such content
In general Hyway is vastly superior in quality and airflow / power to Farmertec.
Looking forward to see this old Still and other Tinmanized saws in the wood with Fab W & friends🔥
A very good job of explaining timing
Im not huge on Stihl but always ready to learn. N tin man bellhopoer iron horse are great teacher s
Great vid very well explained for the laymen thanks Tinman.

Good video, nice to see highway builds quality after market stuff. TC Tinman...Mahalo🤙🤙🤙
Definitely interested to see where you take this saw. Got one sitting here and may you may just have me follow along

ANy idea what the Rockwell hardness of a crankshaft?
Hey tinman for a reed induction whats the procedure there? You just hog transfers and change the exhaust port? And tighten squish ?
Have a great weekend tinman and “friends”
How would you do on a tripple yamaha 700 srx jobber?
Tinman ok great vid but with all them numbers what is it that we/You are looking for? What is the sweet spot number? I am looking to get into timing saws but I am missing something here.
365. 98 exhaust, intake 123 intake 72 and .020 popup? Thought for 24" wood?
those are great flywheel puller.a have same puller,using it for my Ilo engine.

Hello from Vancouver island 😎
If your stihl fly wheel puller is m22 it should fit the 153. Just in case you will need to get it off once more
Enjoy your videos😊
What timing numbers would you recommend for a Stihl 241cm working saw?
For max tourq and throttle response
Love the Husky's but I have an 039 that is a BEAST. It is really hard to overload that machine. It has a lot more grunt than my 372XP
“Back in the day.” 😂😂. You’re 12 years younger then me.
Good video bud there pretty close eh🪵👍

Hey Tinman do you find the after market parts are generally becoming more accurate and better quality? Thanks for the vid !

Skip tooth maybe
@@Buzz-vz2js yeah I was going to put a full skip chain on it
It also depends on what kind of wood you are cutting.
@@aldredske6197 I’m from Australia if that gives you any indication
@@willtrippett6578 It will definitely have its hands full. I wouldn't probably run more than a 24 inch on it. They pull a 24 inch pretty well in the hardest oak trees we have here.

Beauty. Lol that’s the saying of Canadians everywhere .
I'd throw seals in regardless while it's down this far
I have a tool like that for my 372
nice!
Asawlting saws on a daily basis
Only original stihl, no ported ( i work stihl service 27 years)
