Steve's Small Engine Saloon when u where adjusting the low speed screw and the chain moved was it on or off? Also u did i twice once before u tinkered with the idle screw and once after was it on after as well and thanks this well help once i rebuild my carb on my ms210
I have a bran new Husqvarna 460 rancher it will not idle and seems the high low screws will not turn ?????? Please help
Will check it out.
You can make a tool to adjust husqvarna carbs out of a bic pen. Gut the pen then heat the small end until its soft and force it over the screw. Let it cool and you have a free custom adjustment tool.
@@jackk8422 thank you sir your are brilliant
Took my chainsaw to the local Stihl dealer and they said I need a new carburetor, so they couldn't fix it. Took it to the Stihl dealer at the neighboring town and they made adjustments and it was good to go. I used it once and it crapped out! Found your UA-cam site and followed your instructions from chain tension to carb adjusting. BINGO!! You are the man! Better than buying a new one, which I was getting ready to do. So thank you so much, Steve.
You're Welcome...
I found the same thing, it pays to check out the different stores to find the best snd experienced stihl mechanic, they save a lot of time and dollars even if you have to travel to them, thanks Steve, your advice is always good.😊
I brought mine to a Stihl dealer because the brake had been stuck on since day one. They wanted $500 to fix the brake which never worked in the first place. Did it myself for free and replaced my fried clutch while I was at it. DIY is best for chainsaws
I know this video has been out a while, but it’s still the best on UA-cam for tuning a 2 stroke carb. Thanks for sharing.
No problem!
It always will be! Steve makes every engine job very simple. No opinions just facts. He’s an excellent teacher. Thank you Steve for all your hard work and dedication to us. ❤
I'm surprised you are still reading the comments on your circa 2018 video. You, Donyboy73, and Chickanic have helped me maintain the power equipment that our volunteers use to maintain 15 plus miles of public walking trails in our town forests here in New England.
Hey. I told em Steve sent me,,,..,,,and ,,,..,,,they gave me a brand new saw man!!! It was a SeeSaw but that thing was MINT!!!! No but really thanks Steve.. thanks for making informational videos like these purely because you like helping people without payment.
Thanks again brother.
Thumbs up for this being one of the best damn videos on this topic, still relevant in 2023.
Thank You...
And 2024!
I owe you a big HELL YEAH!! I was given a Poulan P3816 by one of my firewood customers. It was rough in and and out but I did get it started. I did thorough cleaning and maintenance in and out. Then, found the correct spline tool through DonyBoy73. I then watched THIS video three times and applied what I learned. No limiter caps, BTW. I followed your tune up instructions and she is screaming. Nice idle a quick punch on the trigger. Top end? Goes through a 16" diameter Oak lol quick with no sign of bogging at all. I replaced air filter and bought her a brand new Oregon 16" Bar and Chain Combo. I then went to your other video to confirm proper chain tension and it's on! This poor saw was barely crawling when I got it. Now? Thanks to you it's a whole new saw!! I'm getting a log delivery midweek. Can't wait!!
Right on Jim! Thank You...
Been messing around with saws and weed eaters for 30 years. Never needed to adjust one until I got a still 210. It has been no idling and only wanting to run wide open for 6 years........today, I fixed it. Thanks to you.
You're Welcome...
After trying to follow the directions in the stihl owners manual, I could not get the idle correctly adjusted. And I wasn't sure if I had the low speed setting correct. So after struggling for a few hours I gave up. Then I decided to do some research with the UA-cam mechanics I trust, of which Steve is one. Danny boy 73 is another. Individualized repair is the third one I trust. And of course Steve is simply the best with his explanations experience and simplicity of repairs. I can't thank you enough Steve because you've helped me time and again. It's so refreshing to have a true professional know exactly what needs to be done and then show the novices like myself how to effectively make it happen. I am again in your debt Steve. 👍👍👍
Glad I could help
My settings were Low 1 1/2. High 3 turns initial setting then fine tune using your method thanks ran perfect after using your procedure !!!
Great to hear!
Found a MS 650 on the cheap because the previous owner thought it ran like crap. Being almost 85cc I had high hopes. He was right. It bogged down when I hit the gas, 4 stroked a lot and it just didn't want to rev. I bought it anyways. I'm not independently wealthy so the thought of a dealer visit was making me sweat. These straightforward instructions got it running like a beast. Thank you very much.
You're Welcome...
I know this is an older video. But I put a different muffler on my saw and wow. What a great teacher. I've seen alot of videos about this but this is by far the best of all. Oh by the way it runs awesome now!! Thanks Steve!!
You're Welcome...
Is your new muffler have more ports in it? I’m trying to do the muffler mod to mine so this video is great for tuning it afterwards but if I can buy a muffler ready to go the better! I have an MS310 btw
@@Blankman776 it's a bark box from West coast Sawa.
Saw I meant . Sorry for the typo
@@Blankman776 bought it from Walker saw shop on line. And it is a beast of a muffler!!!
Your idle speed will get slower and eventually it will die also if your low speed is too rich. Usually if the low speed is too lean the engine idles surges before it dies and has trouble coming back down to idle after acceleration along with bogging on acceleration. This is probably the best tutorial that I’ve seen on UA-cam.
Thank You...
@@williamwallace9620 Sounds like it’s just a tad too rich. If it revs up ok,then you let it idle for awhile and it hesitates on acceleration, it is loading up with too much fuel. Turn it clockwise (leaner) about 1/8 turn on the L screw.
Hahaha... all those "thumbs down" viewers must be small engine mechanics who think they are being hard done by... I have literally saved hundreds of dollars on small engine servicing since I started watching your videos Steve... You're a fair dinkum bloody legend mate...
WOW! Thank You...
Tasmanian nut
I think the thumbs down people are just anti beer people
💯💯💯 this is super easy. FINALLY had the time to sit down and learn me some chainsaw tuning! WOW!
Sometimes a thumbs down is a stray touch-screen tap, cat jumping in a lap, or, I don't know, someone looking for a rock video with chainsaws?
Thanks to this presentation, I'm going to have a functioning chainsaw for the clean-up after Hurricane Irma. I couldn't get it run worth a dang prior to viewing this. Now she's running sweet as can be. Thanks, man.
You're welcome...
Holy Cow that was easy. It only took me 5 mins to get it adjusted. Now she purs. Just tested it on some hedge logs and it powers right through. Thanks for the very easy to understand video.
Great to hear!
Every time I get a "new" saw in my hands, I refer back to this video. Such a great channel.....thanks Steve!
You're Welcome...
@@StevesSmallEngineSaloon GOD BLESS THIS MAN! By far my favorite UA-camr no IFS, ANDS, or BUTS! KEEP IT UP BROTHER!
🇺🇸🍻🎉✨
Why would anyone thumb this man's videos down i have not seen one of his videos that deserve such reaction.
Thank You...
I just want to thank you for this video. I have a Poulan Pro PR5020 that I've had for a number of years, that never wanted to stay running for more than a couple of minutes. That led to some trouble getting the saw adjusted, but holy hell, it runs amazing now. I cut some deadfall yesterday that had fallen in my yard months ago, and the saw stayed running for 30-40 minutes without shutting off once. It ran until the gas ran out. I am so happy I won't have to curse at this thing for being a pain in the rear anymore. I got a set of carb adjustment tools on Amazon for $10, so now I will be able to tune my TroyBilt 4 stroke weedwhacker/brush cutter, and my Ryobi backpack blower I found on the side of the road years ago. My wife and I just acquired ~35 acres, 30 of which are wooded, so this was a lifesaver. Thanks again!
You're Welcome...
Where I live our local dealer say's "it's illegal to own a spline tool" so I bought one on eBay. Thanks for the tip. Enjoyed the video.
Yup, some dealers are clueless!
Yeah its very illegal the chainsaw police are gonna come getcha
Wow trying hard for business id call them out.
They always say that.
I keep coming back every year, or so. Wish I could re-Like it every time 👍
Right on
Hey there Steve, first off I love the channel. I have learned quite a bit here that's has helped me move forward and improve in my own shop. I didn't have Chainsaw after Hurricane Sally hit and ended up cutting large branches and other debris out of the road so I could get where I need with a DeWalt 20 volt saw all. It quickly wore the flesh of the inside of the thumbs where the saw rests. So I bought the cheapest non running chainsaw listed on Facebook and taught myself how to repair them. Well it's been a couple of years and I have sold a couple hundred saws. I buy them broken down, fix them and sell them on Facebook. I give a 30 day warranty and have only had 1 come back (from my brother and 2 years after I sold it to him. He misunderstood a 30 day warranty to be sure it's all good for a lifetime no questions asked bumper to bumper warranty. He took a non running saw home after having it run hot and not bringing it in to be checked out and kept on running it. Scored the piston really bad. And was clearing land with a Poulan Wild thing. He tried to get me to let go of my Stihl MS260 or my 046 but after seeing what he did to the Poulan I suggested he called someone that knew what they where doing).
Anyway, the reason I'm commenting is this. I have this echo PB-2100 blower I just changed the carb on. The L screw has no slots, no other way to grab ahold of it except by a pair of pliers to adjust it. And this thing needs adjusted really bad. How do I go about adjusting this carb if there is no way to turn the L screw. I'm sure the manufacturer didn't intend on anyone using pliers. But this thing is running hot and the RPM's on idle as well as when it's wide open only has maybe a couple hundred RPM's difference. See what I mean needs to be adjusted? I'm trying to attach a picture of your carb so you can see what I mean. But I can't find an option to

Thank You...and You're Welcome...
Steve, thank you a lot. Yes, it took me a while to adjust my Stihl 023 after returning from a greedy dealer. My piston rings broke and screwed both the piston and the cylinder. Dealer asked from me almost the price of new MS230 to fix it, so I retrieved my saw from diagnosis back (yes, I was charged for diagnosis too). They returned it to me in two boxes, disassembled to almost the last piece. At that point I decided to never go back to that shop (or any other) and to learn to fix it by my self.
I learned A LOT from your videos, with that knowledge and also with what I learned from other places on internet i fixed and fine tuned my saw and I'm expecting many more happy hours with my beloved saw.
I'm hoping for more useful videos from you, next tasks are fine tuning FS55 weed eater that returned from shop still stalling, and Briggs&Stratton soil cultivator I cannot fire up after sitting for almost two years.
I'm sorry that we live so far apart, otherwise I would love to drink some beer with you!
Wishing you all the best, keep up the good work man! Greetings from Croatia, Europe!
I'm so happy I could help my friend....
@TheJR1948 Just spent under a bill to be told could not tune the saw, glad to sell me a new carb. Managed to screw up the needle settings and charge me for messing up my saw even more.
Man...
I just saw this video and adjusted my chainsaw that was dying every time I press the throttle..you are the Man!! Brother..
I'm gonna get me a Miller Light right now..
Steve, I wanted to thank your for all the chainsaw tips you have provided within your channel. I have a 1998 Mcculloch 3200 chain saw that I purchased new and used it one time in 1998. Once done I put it under my work bench, never drained the gas, bar oil or even cleaned it before storing. Have been carrying it with me through multiple moves and I now need it. Assumed the wrong thing to do was fill it with gas and see if it would even start after 21 years as I didn't want to wreak anything. Have watch most of your videos concerning what needed to be done like, replacing all the lines (gas & oil), cleaning the saw, gas tank and oil reservoirs, rebuild the carb, chain adjustment, bar oiling and adjusting the carbs. I'm pretty mechanical but your videos were extremely helpful and very much appreciated since this is the first small engine I've worked on. That saw is now running as good as when I purchased it. I hope you are still reading emails from this particular video as it was the last I needed to bring my Mcculloch back to life. The last thing I'm wondering as no one has addressed it for the Mac 3200; is there a way to adjust the bar oil delivery? I looked around the saw but couldn't find any way to adjust the amount of oil. Seems that it is dripping and throwing allot more oil than I remember. There is no leak that I could find and I guess too much oil is preferred over not enough oil. Anyway, thanks again for your very informative videos. I will now have a well deserved Shock Top.
Kinda late, most likely it's not adjustable.
Most saws aren't unless they're pro grade and some farm/ranch grade.
My experience is if there's extra oil that's an extra cushion and the saw appreciates it.
I've never stopped cutting and grumbled that there's too much oil.
You're likely leaking oil and need to look at the connection between the pump and the bar along with the connection from the oil tank to the pump.
Excellent video, thank you!
A note on top RPM: the forces on parts are proportional to the RPM *squared.* At higher RPMs the parts are both going faster *and* have less time to change direction.
* 10% high (110% of, or 1.1 X rated) RPM means 1.1 x 1.1 = 1.21 X the rated forces.
* 20% high RPM: 1.2 x 1.2 = 1.44 X the rated forces.
* 50% high RPM: 1.5 x 1.5 = 2.25 X rated force.
Expect it to break early if it's running over the rating.
How do I find out what the rated forces should be?
I have an old McCulloch 3200 that would not start. There was no spark at the plug so I replaced that and it started. I then tuned the carb as demonstrated in your video and created monster!! Tuned the "L" and set the idle and you aren't kidding about that "H" screw - damn! I had to turn it back a bit.... but now it idles great and everything works as it should. Thanks!
You're Welcome...
Good info. I learned how to adjust a carb via an rc car nitro engine.
There you need to find the sweet spot, but control temperature.
Lil nitro engines love being lean, but the power will fade as the engine starts to melt.
So i always tune to run as rich as possible, but to run well.
Idle, run smooth, but won't flood it self.
I really appreciate "this is what you are doing when you turn this screw" explanations. I can work with this kind of instruction! Thank you !
You're Welcome...
That was a great description of finding the sweet spots, even without the demonstrations! This is adjusting a clean saw, without other issues. If your saw ran well before, your carb adjustments are not your problem. Only adjust a clean carb. that you run to warm up, and break in new diaphragms or saws that sat for awhile. Then set correctly, as Steve shows. When it acts up down the road, fix the actual issue. Don't automatically go to the carb adj on a saw that was set fine; that isn't the issue; usually.
I have seen some very weird methods people use to set their jets correctly, and am learning some technical "precise" methods....factory settings; however, IMHO as someone with limited experience, but a 99% mechanical reasoning aptitude, Steve just showed you how to set any 2 stroke carb. correctly. I do this exact tuning by ear, as Steve describes, and my working saws are quite old.
Thanks Steve! No time wasted like many videos with unnecessary irrelevant chat. Straight to the point with a good explanation of each vital point. I'm now going to have a go at the 2 Stihl saws that won't run properly. I am so fed up with self-help vids that have to introduce their dog, where he sleeps, how long they have lived in the back & beyond, and even on occasions their grandma!

Steve, without doubt your videos are the clearest, easiest to understand, thorough, and very best of anything out there. Mega Kudos to you!
Thank You...
Needed a chainsaw. Boss gave me his MS 250 for some scrub work on one of his properties. Hadn't run in 2-3 years. Looked like bar oil was in fuel compartment...no gas. Put some new gas with Seafoam and Amsoil stabilizer in tank. Swished it. Dumped it out. Refilled tank. It started almost immediately. Smoked like a bastard for a couple minutes until warm. excellent throttle response. Bar had been flipped. Chain was in bad shape. Replaced both. THEN, I went through YOUR video (because I save them). Chain was rotating at idle. Set the LA screw for chain creep. Then, set the other screw for sweet spot and a minus (ccw) backout for "perfect". Runs perfectly. Your my guy, Steve!!!
Thank You...
Thanks man! I saved $240 by replacing my own carb ( and I am semi dufuss). Your video helped me tune the carb. Actually, my old Stihl 026 has the carb adjustments on the side. Once I dialed that in it ran like a champ. Next, I’m going to learn chain sharpening and winter storage!
Great to hear!
FFS, 25 years i've been using chainsaws professionally and I Stihl (sorry) learnt a couple of things from this great video. Nice one Steve, and thank you
Thank You...and You're Welcome...
Bought the wrench off of Amazon for my Husqvarna for the H/L screws and the flathead for the idle screw is on the scwrench that come with the saw.
I tuned it Steve’s way and man does she purrr and respond so much better.
Thanks Steve for a great video!
You're Welcome...
My chainsaw has a new lease on life thanks to you. I had issues, starting, idling, restarting, and wide open throttle operation for the last 8 years. All those issues have been resolved.
I tried someone else’s idea adjusting the carb screws but it did not help the issues. You saved me a bunch of frustration going forward and I wanted to say thank you again.
The taste of beer, the smell of gas, the sound of a well tuned engine. Doesn’t get any better!
Great job Steve.
Thank You...
Yep nothing better than smelling what you ate from the day before.
I am a university professor, and former Dean. This guy is one of the best teachers I have ever seen. Fantastic. I am humbled.
WOW! Thank You...
This is by far the best description of how to adjust a small engine carburetor I have ever seen!
I have a 16-year-old chainsaw that has been saved from the scrapheap.
I had replaced the carburetor which improve the saw but this did not bring it back to 100%.
I received my specialized carburetor adjustment tools from Amazon and put this knowledge to work. My saw is back to 100% !
I have another saw with the same problem I’m wondering if this is all it needs.
Just in case anyone’s wondering My chainsaws are Echo with Wulbro carburetors.
Thank You...
I’m up to three chainsaws saved with this method.
This was the best video, and the only video, that I have had the mystery removed, from tuning the carbeurator on a chainsaw. Only in this video have I gained an understanding of the relationship between these set screws. Thanks for the great explanation.

Watched this and tuned my 80's hand me down Stihl 026 after rebuilding carb, new spark plug, new impulse line, new fuel pickup, did compression check. starts up from cold (not just barks) on 2-4 pulls with full choke, older model with no decompression valve. Works like new

No kidding! In a sea of internet crap we find Steve's channel that actually has an expert telling you how it's done. Thanks Steve, you coached a surfer how to fix a chainsaw. Runs awesome bro!

Thank you for sharing how adjust your carb.
Steve thanks to your videos, I have now replaced the carbs on my weedeater, chainsaw, and leaf blower, now they all run like new. Thanks again!
Nice work!
Steve you are absolutely incredible. You explain everything so well it makes perfect sense. Keep up the good work, we all really appreciate it. Thank you!
Thanks, will do!
Thanks for this Steve. I changed the carb on my Mculloch (same machine as a Husqvarna 453) for a Chinese one (12 bucks) and it was doing exactly what you described in the first instance, idling but when left for a few seconds it would slow and die. I did the low screw adjustment as you described and it idles perfectly now.

That is awesome!
Hi steve,love the videos I’ve been binge watching these. I’m in the uk and done a four year apprenticeship on small engines and large turf care equipment. I was always taught to tune a chainsaw on high speed till it was my Forman called four stroking then back it off. But I have now ordered a digital tachometer! Thank you
You're Welcome...
I live now in Mexico, my cabin is located at 3000m altitude, i believe that could also affect a bit. I also had to adjust my L screw- turn in-clockwise IN 2 or 3 turns. Now works perfect all the time.
Jānis Liepiņš That makes perfect sense at altitude. The density of air is lower so there is less oxygen being sucked in with each piston stroke. So turning the mixture screw inwards (clockwise) reduces the amount of fuel to match that oxygen reduction. It's surprising how much that change needs to be with engines - how sensitive they are.
Amazon sells several kits of chainsaw carburetor adjustment and other handy chainsaw tools like brushes, picks, etc. Kit came with something like 14 different types of carb special tools for a variety of manufacturers. Whole thing was less than 20 bucks and comes in a nice zipper case. Found the one that fits my Craftsman perfectly!!!
Sorry I forgot to add that I love your channel, Steve!!! you have bailed me out of a few things with your great tips and chill approach. Thank you!!
Steve, I want to say Thank You for the time you take to make these videos. They have saved me a whole lot of headaches. Besides that, you appreciate variety in your beers! Thanks again.
You're Welcome...
I'm impressed. You did a great job explaining this and didn't waste my time. Each point you made was also very well illustrated. Thank you very much.
Thank You...and You're Welcome...
After just receiving an 11 piece carb adjustment tool set for my old school Husqvarna 359, I quickly realized I can adjust it simply with a very small flat head(which came with the set). Thanks for the videos!
Same here
Way to go man, despite being almost 12 minutes long, you didn't waste any time. Exactly what I was looking for!👍

Hi Steve. Great explanation! On the high side, I usually lean it out just till it starts to run away then back off until it starts to "break" a little. Then under load it smooths out because the fuel causing it to break is being used under load. If that makes sense lol!
Yes, that's what I've been told too, just adjust the hi side until it starts to "four stroke" under no load.
Many thanks Steve, I have been fighting my MS210 for years and I did not want to remove the carburetor because it ran relatively good at full throttle but was idling to fast and did not respond well to full throttle. after you showed the low speed adjustment screw and i tuned it like you said the saw is idling and responding like it should. Thanks WB
You're Welcome...
Excellent video on chainsaw carb tuning. At 11 mins long, it looks as if it's too long a video, but it's really worth listening to the whole thing. Steve explains all the necessary stuff to help you understand what's happening, at a pace that's not too slow. Great job, thanks :-)
Thank You...and You're Welcome...
It’s worth understanding the “fast idle” mechanism when starting. The starting choke position engages a fast idle which stays engaged until you blip the throttle. This makes it much easier to start (and restart when hot). I never really appreciated this mechanism until it stopped working after many years of use due to wear in the metal levers on my Zama C1Q-H64.
Nice tip!
Thanks Steve. I illegally purchased thru Amazon the adjusting tool for my Husky. Dealer wouldn’t sell the tool and didn’t have a tool?? I followed your instructions with great results.
I struggled to understand all of the other information on tuning saws until watching this video. You are a legend Steve. I’m no expert but I can do basic tuning on a saw now.
Awesome! Thank You...
Dude, I am 72 years old, you did such a good job teaching! To some , just teaching us like a 5th grader is the best! Thanks for the lesson , Dan
Thank You...and You're Welcome...
I agree, best video out there that I've been able to watch hands down! Great job, specific and to the point!
Thank you. This video was very helpful. My chainsaw was set to 6300 feet above sea level when it needed to be set at sea level. Now it can idle regularly without shutting off.
Nice work!
Hands down the easiest to understand video for this topic. Fantastic job and thank you so very much. I've already came back to this a couple times because I forgot lol
Right on...
Me too
Great video. Thanks again I've got some years on me and I messed with chainsaws and engines all my life but it never hurts to have a refresher course because sometimes things just kind of slipped my mind and this is a great instructional video for adjusting a carburetor on a chainsaw which is so important for the performance of that chainsaw so is thanks again, take care!
Right on
I just finished a 20 year career in the fire dept. I used and maintained a lot of stihl chainsaws and I wish I had learned this early on.
Right on
Getting expensive running one or more of my dozen saws to the doctor once a month...
So here I am self education, as is usually a pleasure, on UA-cam!
Steve, you do not disappoint. I'm a newbee to you, but not for long!
Excellent instruction and enjoyable listening & watching...
Thank you very much!!
PS. Hoping you put up a few vids on Huskies as 7 of my boys are that.
well thought out. us guys that do this daily know the ins and outs and there isnt really a way to describe how to get a tune to 100% without hands on learning. this is a quick and to the point basic video and gets you right in the ball park. well done!
Thank You...
Man, Ive been struggling with getting my saw tuned for SIX YEARS! It would run just good enough to use it. First try after watching this and it runs like a top! Thanks You!
Glad I could help
I agree. Thanks for the explanation. Over revving a chainsaw is never good. I own 2 husqvarnas a 450 rancher and a 142 with 16 inch bar. I have cut more big wood with the 142 than most people would try but I always kept the rpm to a limit where it runs smooth. Even with the narrow chain it will still out perform any of my buddies bigger saws. Once I get to know the 450 better I will have a great combo of saws. One for big cuts and the little one to chop up small stuff. I am a big believer to have hand sharpened chains so the saw does the work and no need for down pressure. Thanks for the video.
Steves Small engine Saloon has a big heart. The next time someone asks me how to tune a small engine I am telling them to bring me a case of beer and watch your video. The only question would be what kind of beer. I will leave that to the beer experts because I will drink anything. Your videos always lift my spirits.
P.S. I have been building and tuning engines for 50 years and did video production for ten years. I know how much effort and skill you put into both. Keeping it simple is harder than it looks and you make it look easy. Thanks from TheOldChainsawGuy
Thank you my friend. Awesome comment....
Thanks!
My dad talks highly of your videos. He's damn good at small engines.
Great to hear!
This video is like watching a master teach an apprentice. Thank You!
You're Welcome...
Good video. Had a saw serviced at a big shop in Washington 400ft of elevation then moved to Montana 5000ft of elevation. Couldn't believe how much different it made. Had to tune saw all it would do was surge when you hit the trigger, and wouldnt idea for more than a second or 2
I've watched a lot of similar problem solving videos, but steve has to be the best!!! thank you
Wow, thanks!
Keep up the good videos, just note or two,, That high speed screw adjusts the mixture, leaner mixture equals higher rpm at wot, too lean will burn it up, in this video he left it a tad rich, and that's fine.
It's important to use the best oil and fuel, the stihl ultra synthetic is the only one I use anymore, keep the ratio at 50/1, too much oil can actually make a saw run lean, as in the oil is displacing the fuel, so tune to your mix, and if you use opti oil, never mix it at 50/1, only mix at it's 100/1 spec, it forms very hard little granules that destroys engines if it's got too much opti oil in the mix.
Thanks
Man id been struggling with keeping mine running for some time. But this video helped get it running perfectly again. It showed me that there was an idle screw... Mine was hidden in the black handle bar and i just never noticed it, i assumed it didnt have one. But i tuned it and shes back in action. Thank goodness because i was about to dismantle the whole thing ha
I just end up rewatching this video every season to remember how to do this 👍
Right on...
Only if there was a way to add more thumbs up
For those that like to finesse things, Steve's instruction on the low speed mix is great. I add one thought..... I do a little tweak, I go about 1/3 of the way towards richer from the sweet spot to the rich side drop. For 2 strokes with no accelerator pump like they had on old cars, a tiny bit of rich condition lets the engine mix go more to optimum as the RPM's are climbing. the speed climbs, then the mixture catches up, makes it run lean during RPM climb. if it starts out a bit rich , the acceleration induced lean condition is fought off by starting out a tiny bit rich. Old dirt bike trick to kill any lag. too rich and the thing loads up though.
He did that.
That's what he said
I just purchased my first Stihl .. the ms391.. it was bogging when I pulled full throttle. This was the BEST video and explanation including Stihl vids.. THANK YOU
Glad it helped
EXcellent job, Steve. Thanks for staying on task and explaining well without going all over creation like some sites.
You're Welcome...
I went through a dozen videos... yours was the best, easy to understand & to the point. Thank you
Thank You...
People limbs cut off
Just watched the "tune & adjust carb".
So if the high and low screws only adjust idle speed then what the hell is the adjustment screw that actually moves the throttle butterfly effecting THE IDLE really do? The air fuel mixture? LMAO what you telling, a certified small engine repair person, that the high - low adjustment screws are not air-fuel mixture?
@@MoparManiacHemiFever low speed screw is mixture screw
@@MoparManiacHemiFever he said the idle adjustment does that, the other two are mixture adjustment.
Thank you Sir for the great instruction. Saved me a trip to a repair show and for sure some money out of the wallet. My saw responds well now. I appreciate you!
Excellent!
First tuning video that actually explains the tuning process and doesn't ramble about how this screw does that and this one that and all the other crap, just tells you what to turn when and how it should sound.
ZombieFighterOf2001 When he tipped that beer, I thought here we go. I was wrong. Clear and concise good info.
Thanks guys..
I really really appreciate this video. Thank you so much for explaining clearly. I hope you got paid a lot for that promo at the start. YOU DESERVE IT
You're Welcome...
Was hoping you would go into tuning the saw while cutting wood for it to sound like a 4 stroke engine, that's how I learned.
Very good explanation of the basics and plenty of caution about blowing up a saw.
Hey man, I have watched dozens of chainsaw tuning videos, and everybody has their own little take on it, but this one by far was the most educational and accurate chainsaw tuning video on UA-cam!!
WOW! Thank You...
Steve, your instructional videos are absolutely awesome!!! The way you explain things is so helpful and worthy of a thumbs up every time!!!! I can't thank you enough.
Glad to help
Steve, this video saved my day. A huge THANKS! It’s amazing how good of a mechanic I am...AFTER I see how it’s done.😜
You're welcome!
Hi Steve: A lot of people who post videos on how to, don't know jack S_ _ _ . You really know your stuff. We as viewers have to know the difference between who know what there talking about and who doesn't. Your instruction on how to are excellent. Thank you ever so much. I also like your little beer intakes. Your the man. Thanks for all you do for us folks who once in a while need your help. Keep the good tip coming .
Wow, thanks
That was the best explanation of adjustments for a saw carb. You kept it simple, thorough, and on point. Thank you.
Glad it was helpful!
Hey Steve,
Regarding removing the limiter caps, is this something we should always do? For example, if limiter caps exist, do we remove them? Weed wackers chainsaws etc?
Kind regards
My two cents regarding Stihl stuff, is no. Not always anyway. In my experience, the folks at stihl have thought it out pretty well, and most problems come from inexperienced people fiddling with stuff. If it's running well with the limiter caps on keep them on.
Really helpful video. Very clear and descriptive. The Stihl Dealer near here said my old 026 chainsaw needed a new carburetor, only available online and that I'd have to install it myself. When I took the air cleaner off, the carb was clean as a whistle inside. No sale on that - I simply cleaned all the oil out of the air filter, twiddled the L, H and LA jets and she runs like a champ. Just ordered the tach to finish the job.
Great to hear!
Excellent ! I am a ASE automotive mechanic and these small engines kick my butt #1 Video on this procedure, and may I add, if it only idles and stalls with acceleration clean your spark arrestor (First). That may be your only issue... Thanks
That digital tach is the most amazing thing I’ve seen in awhile
Hello Steve,best regards from Manchester,England. You're a legend!
Thanks Buddy, WOW, what a compliment!!! I get about 10% views from the U.K. I love you guys over there....
MGD AND STIHL...THIS DUDE IS MY HERO!!!!
Right on buddy...
I have asked literally every male friend of mine who cuts firewood and/or timber to help me adjust the high idle on my saw (28av wood boss ❤), but no one seemed to be able to help me! Now am I going to be the only one in this neck of the woods that can tune a saw?! And a chick, at that?! Ha! 😆😉You’re awesome!!! Much thanks! ☺️
Right on
Steve the chainsaw whispered, most clear instructions have seen on YT...just subs
Thanks buddy...
Hi Steve, I was just wondering why you didn't mention listening for the 4 stroking? Going for highest rpm doesn't always get you the most power. I've always heard it's better to be a tad rich than a tad lean.
I heard you can't be too rich or too thin.
