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
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...
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...
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...
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...
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...
Best tutorial to set up a carburettor by a country mile. Faultless and lead to a sweet running 028 and 048. Thanks
Thank You...and You're Welcome...
Way to go man, despite being almost 12 minutes long, you didn't waste any time. Exactly what I was looking for!👍
You're welcome...
Chain saw home made. Bar striathening tool
Golf ultra
3 minutes of rubbish at the start
Why would anyone thumb this man's videos down i have not seen one of his videos that deserve such reaction.
Thank You...
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
I keep coming back every year, or so. Wish I could re-Like it every time 👍
Right on

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...
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.
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.
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....
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...
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!
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!
Right on....
ted olmsted engine ideas fast when turned down on idle it shuts off
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...
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...
Steve, you're awesome! I have taught senior high school for 31 years. You're a natural! Huge Thanks!
Thank You...and 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...
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...
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
I watched alot of UA-cam videos for different issues that I couldn't figure out or know how to do....when it comes to small engines I now watch usually 3 videos for the issues at hand but Steve I have to tell ya that you are my go to person for the repairs!! Although the other guys are ok good....but you are DANG GOOD!! the way you get to the point not rambling on and on and on and explain in GREAT DETAIL how to make needed repairs. Thank you so much for being short to the point but yet thorough !!! Thats the sure way of knowing you are a professional at your job.
WOW! Thank you Buddy...
You're an excellent teacher, and this was the only crystal clear instruction I could find online. Thanks for the effort.
Thank You...and You're Welcome...
Just had to do this to my Stiga and it was spot on and now sounds sweet as a nut. Couldn't have done it without this tutorial so thank you Steve!
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
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!
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!
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...
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.
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 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.
Yours was the best carb adjustment video! Clear, concise, *complete*, and accurate information. I poked around UA-cam for 20 minutes - yours was the only I saw that referenced initial idle settings. This was key to solve my issue. Many thanks!!
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...
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.
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!
Thank you for this more detailed explanation of saw tuning, and the tips for finding the right settings when you don't have all the tuning tools. I understood most of this already, to a good degree, but you helped clarify a few things. I also appreciate the tips for field tuning.
Right on ...
Thank you for sharing how adjust your carb.
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!
I have recently found your videos and I love that you don’t stuff around with useless information about anything other than the video information I chose to watch thanks 😊
Glad you like them!
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

I've watched a lot of similar problem solving videos, but steve has to be the best!!! thank you
Wow, thanks!
After checking presentations by others this fellow gets it right with clarity that just makes total sense. Others seem to have something else going on that just does not garner my trust. Thanks, Steve!
You're Welcome...
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...
EXcellent job, Steve. Thanks for staying on task and explaining well without going all over creation like some sites.
You're Welcome...
Watched several videos, and none of them worked, your detailed instruction on the detent or the sweet spot made all the difference on a Stihl210. Thank you!
Great to hear!
Wow. My saw was screaming and the chain was racing. Followed your clear instructions an my saw is working like it was new. Thank you!
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
I have been running chainsaw on the west coast since 1997. Steve, you have great tips and knowledge that I will be sharing with newer guys to the industry. Thank you
Right on
Being a newbie and determined to do my best to repair, sharpen, etc my own saw I am grateful for your clear instructions.
Thank You...
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
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.
Steve the chainsaw whispered, most clear instructions have seen on YT...just subs
Thanks buddy...
The only video I've seen which actually made sense! Well done sir👍
Thanks Phil...
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!
WOOOWWW!!!! an actual video explaining carb adjustment properly... made it so simple to understand thanks so much man
You're welcome...
Dude, if you're not Canadian, you're an honourary member.

Howdy Steve from a Texas Rancher.. I showed your video to the fence crews and made them watch as though they were in your Class (lol) and they were able to show me as you have done. They did great!! I ranch 15,000 acre ranch and trees,and heavy branches foul my fence lines. You are great and you have saved me time and money. Come down here for a TEXAS BAR BBQ
That is awesome!
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.
Well done Steve buddy 👍
Thanks 👍
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.
Great video Steve. Great info. on RPM guage -- gotta have one!
Got a link in the description for one...
Every time I get a "new" saw in my hands, I refer back to this video. Such a great channel.....thanks Steve!

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.
How often should you tune your saw?
Hot weather/ cold weather.... Mixing ratio.... changes in altitude.... ring/cylinder wear..... mods' muffler/carburetor/Porting/air filter,etc.
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...
Great information Steve! Question: If you put a different ratio of gas/oil from what you used in the tuning of the carb, will you experience performance issues?
if you changed the mix very MUCH, then YES ! you will experience a tuning difference, and here's why.....if you put MORE oil in the gas, (lower number mix from say, 50 to 1 down to 45 to 1), then the mix will go thru the carb jets SLOWER and LEAN IT OUT....which means you would need to BACK OUT the High Screw a bit, and the opposite is also true ... thin the mix, and it goes thru the jets EASIER, making the tune too RICH....screw the jet IN A BIT and Lean it out a tad.....it works just the opposite of what you THINK, until you mull it over a bit, then you will understand it.....here's why :
the added oil changes the VISCOSITY of the fluid, and it will go thru any orfice SLOWER the thicker it is......have fun.....OnWard.....
Yes Steve, -thanks for the time and letting the viewer hear what yer doing. One dude's comment to you suggested that having a little more oil in the fuel gas can mix, ( how I mix) can actually make the saw run lean. Now I'm confused. Is he off?- . ..the last thing I want to do is burn my engine.
I had a high-speed screw once.
(someone had to say it)
mitchamus nobody has a sense of humor any more, I started laughing so hard 🤣😅🤣
I actually LOLd!
Awe to be young again... those were the days!
Those become low speed screws with age, and in some cases, frozen screws if enough years passed.
@@independenttntn3276 Or worse,some a hole comes over while your at work and drills out the old small threads and retaps it to a much larger diameter thread.
Thanks, from Baton Rouge, La. Your directions are very clear. My 16 inch Sthil now runs great!!! Instant trigger response. You saved me a trip across town and about one week of wait time.THANKS
Great to hear!
My chainsaw is bogging at full throttle, it idles fine and speeds up fine but it bogs down right where I need it to run, any suggestions?
Lean out the high speed screw. That's in or clockwise. Do it while it's running and you can tune exactly how you want it. If that doesn't help, remove or clean the spark arrestor
H screw OR fuel line needs replacing they can pinch and cut fuel under heavy throttle but idle just fine
Thanks for sharing Steve! I really enjoy Your video's. I'm flying RC planes with two stroke engines in them, and I always pick engines where Walbro's are originally fitted. Quite often I run into problems when adjusting them. There's no problem with the H needle and finding the hig revs, but when I throttle down it sometimes takes a while for the engine to drop to idle. And quite often it will stall on me if I get it adjusted so it drops faster. Do You have any pointers to what I should do? You can imagine that reliability is an issue when You have a plane in the air ;).
The engine sounds like it’s running lean What color is the plug? White is bad! Check any carb to engine gaskets/boots for leaks or damage and security. A engine leak check might be required to check crank seals and engine gaskets.
This has to be the easiest to understand explanation of how to adjust and set the adjustments on a small engine carburetor ! Thanks Steve !! I am saving this video to my archive.
Glad you liked it!
Steve! Just followed your guide tuning my 372 and it’s running better than ever. You’re the man! Thanks abunch my dude.
Nice work!
Hi Steve, I have a problem with a stihl MS 250. It fires after full choke and when starting in secondary postion it just revs up very high for 3 seconds and dies. This happens even when the throttle idle screw is completely backed off. I have tried a new diaphram in the carb and adjusting the H&L screws after using a carb cleaner and air duster. Fuel and spark plug etc is o.k. I have used various chainsaws since 1982 when we had the Dutch elm disease. I even built my own log spliter back then. Having solved many problems inthe past this one has got me stumped. Help please.
Did you check the tiny screen filter inside the carburetor? You have a fuel restriction somewhere, that screen is the first place to start
I think you so much for teaching me so much about lawn mowers weed eaters everything you gave me an opportunity rather than going to college to basically learning from you takes lesser time or evening going to
a four-year course or a trade you give me an idea and keep on giving me ideas and keep on teaching you are very excellent teacher
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
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.
I agree with the comment below. Trying to tune up my new (vintage) STIHL 020 AV SUPER and this is the best instruction out there by far. Thanks Steve.
Glad to help!
outstanding vid..thanks
You're welcome...
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!
dont forget to wear eyemuffs as well
MGD for the win👍🏻🍻 best garage beer out there. I generally maintain a 1:1 beer:spark plug ratio. That V8 was fun the other day. 🤣
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
By far the best explained and demonstrated 2 cycle carb adjustment I’ve seen. Thanks, Steve.
Wow, thanks!
You never mentioned weather, do you have to fool with it in the winter? You know real Canadian winter up in Nickel country.
Fool with it when ever it does not run properly....
Mark Bernier I can tune my saw in my yard and it’ll spit chips, bring it to where I cut my fire wood it doesn’t wanna start. Altitude is a big thing as well.
I thought that was syrup country 🤤
@@JRADMAKES Nickel starts where the maple trees stop. Huge mining areas in the north Iron, copper, gold, silver. and of course Nickel
Learned more from your videos than any other channel, now anytime I run into a problem your channel is the first port of call 👍
Welcome aboard!
I just put a new coil and carbi kit in my chainsaw. Watched this as a refresher to retune her. Thanks 🙂
You're Welcome...
Perfect ! Messed up my 064 and I got it running but wasnt sure how and what to do. This was a perfect explanation.
Thank You...
I don't care HOW many times I have to revisit your videos. Every time I search for solutions and I see your channel as a result, *thats* the one I click on because I know it will work. 🎉
Wow, thanks!
This was exactly what I needed. Have looked all over and only this video provided the accurate info and willing to test it to ensure it was right! Thank you!!!!!!
Great to hear!
This is by far the best channel that explains things! Great job
Thank You...
My Stihl Farm Boss wouldn't hold an idle so I went to a Stihl tech where I bought the thing and asked If I could just see what the screwdriver looked like. Turns out he ended up giving me one, even though he initially said he couldn't sell me one. Gladly tipped the guy and thanked him. Given that and your video my Farm Boss runs like a striped ape. Now to get the inductive tach. Many thanks for your awesome channel! sub and like are in order! 👍
Right on
Your video helped me get two saws running good; a McCulloch MS4016 and a Pioneer P41S made in the 1980s. The info in your video works on any saw including vintage ones with the L & H adjustment screws.
Right on
For me this is the best tutorial about adjusting my carburator that I've found. Thanks
Great to hear!
Thanks Steve. My main problem has always been at the low end of RPM. I was only adjusting the Idle screw, result being chainsaw idling too fast or bogging down and dying. Much appreciated.
You're Welcome...
Field Report! I didn't adjust the H screw, but made several adjustments to the L screw on my 16 inch gas chainsaw. Found its sweetspot, and it works great now. Thanks muchly Steve!
Why is the idle adjustment screw labeled "LA"???
LA is the German abbreviation for "Leerlauf-Anschlag" it means idling stop. Stihls are made in Germany.
An English name for LA could be low air, since the screw adjusts the amount of air via the throttle plate. I'm a fan of the saws labeled with I for idle.
Great way to remember that too! Nice...
Ja (German for "Yes")
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
Steve: Your demonstration was so very clear, even a total newbie like me was able to get my chainsaw running like a top. Thanks!
Great to hear!
Just got to watching your videos and already set the carburetor on my weedeater. I would like to thank you and the video was years old.
Glad I could help
