Just like the guy that plays the violins in a symphony .... He can tune his instrument in two minutes ...by ear if something has changed with his instrument he hears it. I always take a new guy aside if he last a couple weeks and we know he's gonna be working with us and physically show him tuning... Put the screw driver in his had an let him make the adjustments ... So when he is running that tool and the tone of the engine changes he immediately knows it needs a quick adjustment ... They respect the tools more...keeps everyone on the crew invested in our tools...they understand that it's with those tools working in top condition that we earn our livings. I got a great mechanic that helps on the weekends... Every week I put the tools in the truck that need a tune up... By the third lawn in the morning everything is tuned up and he's carting a screw driver in his back pocket.... He's the slowest guy weedwacking that I've ever met...

The sweetspot is so small its almost nonexistant. Thanks for the vid, Brian!
+Brian Lawyer I hear ya, we get people all the time who try to do their own adjusting and they make things worse. I've seen a good many saws with the Low mixture screw turned out as far as 3 full turns. lol
Thanks for the video. I cut above 8500 ft elevation and run my 460 magnum on the lean setting. If I turn it towards richer even a quarter turn it begins to smoke. Is full lean setting ok at 8500 ft and above?
I read below that you said you can use the same procedure just substituting the RPMs from the manual which is great but do the 3300 and 3700 rpm rules still apply? I have 194t idle supposed to be set at 3000 not 2500 so does that change those rpms used to adjust at all? Or still look for 3300 then less than 3700
You have to set the 460 up rich or it will beat you to death with the deco valve. Mine was a bitch untilI learned this fact. I set up all of my big saws exactly as you have tuned the 460. I do not want to have rotator cuff surgery. If you are having trouble starting a 460, just pour a half of a cap full of gas down the snout and this will provide enough lubrication to keep the deco from popping out and then tune as described in this video.
even if press throttle just keeps going was ok but ignition coil went so replaced that cleaned it all out and like an idiot cleared out near the adjustments and think knocked it all out now when started just screams as if it wants to take off lol
I have a MS460, my question the compression release when trying to start the saw i push it down and after one pull the release button releases and come up. Is that working properly, or should it stay engaged until the saw starts. Thanks again George, st louis, mo
Is the saw modified for more compression? If not, then the decompression valve is most likely worn. Some aftermarket valves also behave like this. I wouldn't say they are cheap, but a new valve from Stihl won't break the bank either.
Unfortunately I don't get to pick every song on the radio. ;) Plus, that saw was built piece by piece out of a box of parts. That warranty was history a long time ago.
I figure most warranties are tail light warranties, anyway, and not worth the paper they are written on. If something breaks, I fix it. Most products will last if you take care of them, properly. If not, they will not last. That’s about it. Warranties are designed to trap people that don’t have a clue. Warranties are not even a consideration to me.
I think I would understand better if i knew why you were doing some of the adjustments - would love to know how to tune my saws (023,066), I now comfortably do complete re-builds on saws and take them to the shop to tune them........
Basically there is 3 screws that you can adjust. The Fuel Air mixture screw, the max rpm screw, and the idle screw. Basically what you he is doing is finding the best running setting on fuel/ air mix and then setting the idle and max rpm to factory specifications.
Great video, Brian. Very instructive. My question: what does it mean "...saw begins to four stroke"? I do hear a slight difference where you stop opening the H screw -- sounds as if it just begins to 'gurgle', but it's a very minor change. Is that the 'four stroke' sound? Why is it called that? ie. how can a two stroke engine be in a four stroke mode? I've read this term a couple times before in one of the forums, and would really like to understand what it means. Thanks in advance for your help, Brian! ~Allen
By "four-stroke", he means that the saw is tuned ever so slightly to the Rich side. As a result, the saw actually misses every so often, rather than firing on every stroke as two strokes theoretically do. Yes, this miss is also known as "gurgle" or "warble." It serves two purposes - 1.) lets the sawyer know that the saw is not adjusted to the Lean side, and 2.) every miss represents unburned mix which cools and lubricates the engine ever so slightly. At least, that's what my Dad taught me.
so how do you know when the L screw is adjusted perfectly for response? if it bogs down when you pull the trigger at all it's too lean and keep going CCW untill it doesn't bog?
Yes. But if you're on the rich side of the L screw it will also rev up poorly, and may load up (slowly flood out) while idling. Another indicator I've found is if your L screw is adjusted correctly, the 2 cycle engine will start easily. If you're too lean on the L screw it will be harder to start. Disclaimer I'm not an expert.
Ok I have quick question are the limiter caps still in this saw or did it not come with them? I could not get mine to 4 stroke with the high jet all the way rich when saw was brand new I ended up pulling the cap to get it fourstroke is this normal for 460? Also I want to make whole bigger in exhaust outlet how much will it affect the settings do they run a lot higher rpms after muffler is modified?
Absolutely normal. Muffler mods make a noticeable difference in the settings mainly because the stock opening is so tiny on a US-spec saw. They don't run much faster after the muffler mod but they will have much more power throughout the power band. You may end up somewhere around 14,000 rpm WoT no-load.
That’s about how I break them in. I load them up with a rich mix and let them idle on my work bench. They do not even get to see any wood before they have five tanks on them. I usually fill them with gas and bar oil and let them run until the tank is empty. The next day I run them for 15 minutes or a quarter a tank and I keep doing this every day until the get five tanks of gas through them. Then I put them in my saw logs. I will never cut more than a tank a day until they get 15 tanks through them. It takes me about a month to break in a saw to 15 tanks, sometimes a year. My 372 XP that I built this past April has about 10 tanks through it. My MS 241 that I bought in 2017 has 13.5 tanks through it. My MS 360 that I built in 2019 has over 15 tanks through it. My Ms 660 that I built in 2018 has 13.5 tanks through it. I keep good records, too. Every saw that I own (12) have entries in my record book, even used saws. The book details the date, model, what I did with them and how much gas they used and any parts replaced, etc. a fully detailed PM record for that saw.
Your sequence is right out of the Stihl Service manual for the 440/460. It is the same procedure for the 360/361 except that the idle rpm is 2,800 instead of 2,500.
@@Sensei948 I run mine a little rich. I set them 12,600-12,800 for a good four stroke. I do not want to smoke a cylinder and piston in very hot or cold weather. Pushing them to their limits only ends up with a broken saw.I want a saw that starts easy every time I need it, stays lit and relights. I don’t care if someone else’s saw will cut a cookie a second or two faster than mine or not. My saw will still be running when their saw has long since died an ignoble death.
This isn't bad for a baseline.. However when I'm out in it, I will tune it under load. I rely on all 13650 RPMs to take me to day's end. When in oak, I use carbide tipped chains also. Cutting butter with a blade.
2 questions :) why 3300? at manual is 3500( clutch engaged) why not 3500? and why readjusting when rpms turn out over 3700?? and Brian u are really skilled iam lumberjack and the saw run bestialy ! i want to tune my chainsaws :)
3300 because we want the saw idling without the clutch engaged. Readjust the LA over 3700 because at that point the engine is pulling enough air for the H side of the carb to affect the mixture.
Sounds in tune.running. will cut.mine will. I'm just to damn little.460 im about out in 3 hours.just cuz daddy bought you big saw.don't meen u can run. It.I don't like ignorant in the fell .
it doesnt need to be this involved tho especially with a tachometer, screws should both be 1 1/2 turns out to start and dont need more than a full turn. also when tuning the high speed jet, you have to factor in the load you put on the saw when making a cut. shouldnt need a tachometer to tune a saw properly
The chain oiler is definately working.

Forget about trying to dial in your idle speed until you have the L needle tuned.
Sometimes they are so far out of whack that I have to leave the Idle screw turned in until the L is close enough for it to really idle on its own.

2 questions :) why 3300? at manual is 3500( clutch engaged) why not 3500? and why readjusting when rpms turn out over 3700?? and Brian u are really skilled iam lumberjack and the saw run bestialy ! i want to tune my chainsaws :)
3300 because we want the saw idling without the clutch engaged. Readjust the LA over 3700 because at that point the engine is pulling enough air for the H side of the carb to affect the mixture.
Brian Lawyer so i can tune up my ms 261 .. same as this yeap? or 361ms ... have same parameters.. Am i right?
Parameters may be different (will be listed in the owners manual for low idle speed and max RPM) but the procedure is the same.
Friend, the revolutions 13200 max for the saw 372xp oe 2003 are okay?
What tool did you use to check RPM'S?
A Tac like what’s in your vehicle it’s similar to that but it doesn’t stay with the saw it is its own tool

john reilly Sorry! This one has long been sold but lives in as a MMWS cutting firewood in Ohio!
Sounds in tune.running. will cut.mine will. I'm just to damn little.460 im about out in 3 hours.just cuz daddy bought you big saw.don't meen u can run. It.I don't like ignorant in the fell .
it doesnt need to be this involved tho especially with a tachometer, screws should both be 1 1/2 turns out to start and dont need more than a full turn. also when tuning the high speed jet, you have to factor in the load you put on the saw when making a cut. shouldnt need a tachometer to tune a saw properly
