I have pulled the spark arrestor out of my equipment for years.
Haven't started any fires and the EPA has not arrested me yet.
I am 70 years old
OLD SCHOOL BEST WAY
Yep, I have done the same and I'm 65. I feel like a fugitive from justice though, when I use my trimmer I keep an eye out for the "Spark Arrestor Screen Police".
I guess it's really true what they say about old dogs and new tricks.
Watch out for the EPA SWAT team sneaking up on you in their stealth black helicopters.
The forest service has standard (FS5100-1D) for Spark Arresters and 36 CFR 261.52 is the federal regulation that requires the use of spark arrestors in accordance with FS5100-1. Modifying the exhaust to improve performance is always a balance between flow restriction and performance. Just don’t get caught in the forest service jurisdiction without them. Painful and costly potential experience.
One of the many things I appreciate about your vid's is that you get right to the point. Many people who post feel a need to extend the message with a long pre-amble. Thank you for posting content that is relevant, concise, and easy to understand.
Ditto! I came here to watch, learn & go fix my lawnmower ASAP. Great comment.👍
Aye????she took 2 mins mate to get to the point, like most yanks she waffles on before stating what can be said in one or two minutes into 7
That's right!!
Well informed & Awesome content please keep doing what you do BEST. I like looking up your past videos as it’s like a Encyclopedia.❤💯🙏🏽from an avid follower here Sydney 😂
Are you kidding? I’ve learned more in the last 20/30 minutes watching your videos than I ever thought possible. Thank you so much for doing what you do.
A propane torch is the best option for burning off the carbon. You won’t need to scrape anything off possibly breaking the mesh screen or how it’s attached to the fastener.
Love your vids!
acetylene/oxygen torch works REALLY GOOD cremates it.
I use carb cleaner and a brass brush. Works just fine.
Just take the muffler off turn up the radio
👍 I agree. A propane torch does work very well. In fact any torch style lighter, such as a torch style cigar or grill lighter will get the screen red hot, which will burn off the carbon/crud. No scraping necessary.

Usually if we had an old dirt bike with a coked up pipe ,it was time to bust out some Brewskis and throw the pipe in a bonfire for a little while.
I’m a technician myself but have only worked on cars and trucks. It bothers me when I have to take my small engine equipment and let someone else work on it. I have learned a lot watching your videos. Thank you
Same here.. no problem working on vehicle engines, but my small engines, for whatever reason I am afraid. Haaahahaa.
I just use 40 volt. Then I no longer have all the problems associated with small carbureted engines or the stink of their exhaust. My mower still runs on gasoline but they are a lot less prone to trouble than a smaller engine like that of a chainsaw.
LiON riding machines can go an acre, even more. The battery packs are huge.
LiON tech is red hot now. Improvements in utility and safety prove inevitable. Even a silicon battery may arise.
Elderly "snow bird' types hate the noise and effluents from gas machines. Legal issues inevitably will also arise.
DIY'ers like that the new machines simply start and work: No idiot throttle control, somehow, to juggle--to get right.
Even encasing nuclear waste to serve as batteries is already here!: Pacemakers.
Big petrol also sees the writing on the wall': They'll push plastics, instead.
Face it!: It's over!
Howsoever, if they catch fire, you ain't putting it out! Look up the mower fire at the Louieville convention a couple years ago!😮😮😮
Your video was super. You were right on the money about users lugging their engines and clogging spark arrestors. I am a certified Stihl Service Technician and I can tell you for a fact that our shop and Stihl have never, ever refused a warranty repair based upon the type of oil used. Stihl will Double your warranty if you buy a six pack of Stihl HP Ultra oil at the time of purchase. I get a lot of units in for repair with bad gas. Also, I'm sure most owners are running 87 octane gas in their units. Stihl recommends at least 89 octane. So between owners not running the machine properly and using bad/wrong fuel, most of the spark arrestor problems can be credited to this.
I would probably have a heart attack if just one of my customers said," Yes, I read the manual "
You know us men, we don't read manuals!!! Removing the trimmer head shroud and running longer line in the trimmer is the biggest culprit too. These small engines will not run up to full song even if the trimmer line is just 1 inch too long (800 rpm decrease).
As a final note I prefer Amsoil Sabre oil. You can use less and there is less smoke (more complete combustion) and it last a long time in the can.
Thanks,
Keep rockin'

"Stihl will double your warranty if you buy a six pack of Stihl HP Ultra oil at the time of purchase." That's exactly how my local dealer presented the proposition to me.
I just started the video and had to jump into the comments because I've never heard of Stihl refusing warranty based on oil used. And I'm a Stihl dealer.
Mark Amsoil oil I no whith out a doubt is top choice but In so many places it's not so readily available I have been using Quicksilver for many years whith no problems not one time have I had to clean the spark arrestor in my old FS40c I have a ancient Stihl chainsaw. Still runs like a champ cut's like no woodchuck could if a woodchuck could cut wood
Spark arrestors the first thing that gets yanked out the second I get home with something.
I totally read the manuals on all my equipment. I just need to reread them occasionally! LoL!
I was A small engine mechanic from 1965 until I got to old, I have A Stihl bought new 19-20 years ago have never used any thing but Sthil oil runs like new. Good to find your channel, not only pretty but informative,
I have been a mechanic for 40 years but really never worked on small equipment you have shown me a lot I never even knew great job love your channel 👍🇨🇦
I was half way through a 4 hour job and my Stihl brush cutter finally ground to down almost no power. After watching this I had it up to full power in 15 mins. Thank you. You are what we call in Australia, a dead set legend!
Did you clean the air filter after 4 hours of work you should have ! !!!!!!!!
Clean out end of muffler and air cleaner thats all not hard ffs
Crikeys mate, you’re not wrong. She’s a Bobby dazzler. 😊👍👍🦘🇦🇺🦘
I’m much longer than 12 years working on small two stroke engines.
This is another lesson learned.
Spot on tech advice. I just discovered Chickanic, but rapidly becoming a fan. I'm an older guy, have learned a lot of these in a mostly rural life. She has her game down, and expresses these tips as well or better than anyone I've seen. A pro.
*_Agreed. She really knows her stuff & is a GREAT educator. I subscribed to her channel just a couple of weeks ago. 👍_*
Another problem is that bees called mud daubers plug the muffler opening.
I had the impression that the Mud Daubers were hornets. Wont getting rid of them, they like to sting and run.
I think your videos are really informative! You have already taught me some things about small engines. My older brother who has been a real expert on the engines lives too far away for me to take my equipment to him. He had a stroke in 2021 so has difficulty dealing with things he once did on these tools. Your videos are surely going to help me even more. You are so awesome! Thanks for all the tips and advice.
I have always ran stihl two cycle oil & will continue to run stihl oil. However, this episode has totally changed the way I run my stihl machines. Thank you!
I just found you (by accident) a couple of days ago. I'm that typical do-it-yourselfer who gets VERY frustrated when he has to WORK ON HIS TOOLS before he uses them for their designed purpose. Your videos are simple and amazing, all in one!! Thank you SO MUCH for sharing your knowledge and experience in such a professional, understandable, thorough and friendly manner!! (You need your own TV show!!)😎
Yes, burning off a spark arrestor is a great tip. One of the 1st things I check when equipment gets sluggish, it's now a part of routine maintenance. Thanks for explaining it and that some oils and equipment need more attention.
Glad I watched the whole thing. I've had 0 problems with most of our Stihl equipment while using Stihl oil, but that's probably because we use them commercially, at full throttle for most of the day. This is useful information because our least used tool, our hedge cutter, always seems to be preforming lackluster.
I switched to Motul 800 offroad and never looked back. The HP Ultra is a great oil, but I love the smell and less deposits that the motul puts on the table.
That’s the thing has to be full throttle. At least at some point.
Thank you for your videos. I recently had an issue with my Stihl weed trimmer not throttling up. A dim light came on in my head where I remembered watching this video about a year ago and sure enough, the screen on the trimmer’s muffler was blocked with carbon. I burned it off and now it runs great. I’ve also fixed a carburetor on my Honda mower following you advice.
You are a kind person for providing such great advice.
Great advice! And thanks for asking; I'll add a note about my experience LOL. Long story short, after one season, I thought my KM56 powerhead was dead - either would not start or would stall with the slightest amount of throttle. After checking fuel, filter and plug, I pulled the spark arrestor screen. It had turned into an exhaust arrestor - packed solid! Propane torch did the trick. And sure enough, I used to run at midthrottle settings as opposed to wide open throttle.
Fast forward; I've added a KM111 to the stable since we have two properties to deal with, and normallly run both it and the 56 at WOT or idle, nothing in between other than for delicate areas. I have not had to clean the screens on either of them for seven years.
Love your channel!
20 years ago, I purchased a 15 year old Stihl backpack BR340 for $100!! It would not run up off idle, so looking at it I noticed the exhaust screen looked black. When I got it home , I removed the screen and it ran like new. So I bought a new one and was happy with it until 2 weeks ago when it sought on fire due to a fuel leak so I bought a new BR 430 and love how easy it is to srart. Having been a Master Automobile / Truck / Motorcycle & RV mechanic since 1979, i appreciate your straight talk. Please keep it up. I appreciate you.
Really nice, focused coverage of how to keep your Stihl trimer, blower, etc. running great.
Thank you!
Really enjoy your videos. Helps me keep my machines running great. I'm a Firewood guy been doing wood for 40 years and have paid the price for being stupid with my saws. Thanks again for being there for all us Boneheads.

This is great information, I bought a professional Stihl trimmer because the consumer grade trimmers failed on me. I don’t use mine at full throttle so I’m sure I will run across this issue. And yes I bought a bunch of Stihl oil because as you stated the dealer mentioned that I get an extended warranty with that purchase. Spot on, you are awesome!!!
Young Lady I want to Thankyou ,your videos are spot on . This old man has learned a lot from your input , I am proof you can teach old dogs . Your videos have helped me a lot thanks again
Great info! I just had this problem on my Echo trimmer. I got a new replacement muffler on line for pretty cheap, and then it started right up, and stayed running like it wasn't before. Great channel and info. Thanks
Thank you so much! Excellent tips and makes perfect sense regarding running the motor full-on. Wishing you all the best!
thank you. also, i use non ethanol gas,cheaper than engineered gas .also,Amsoil Sabre has stabilizer in it!
Thank you. I am totally impressed with learning so much from you. I am in North Carolina and we don’t have a repair shop like you. I hope your business is hugely successful. Thank you for helping everyone.
You must live Nebo NC.
Thank you for all the great tips on the equipment, your Awesome. It’s refreshing to have someone that is honest and is knowledgeable about all the products that are out there 😊😊
Howdy from East Texas. I've been in the shop reviving a few mowers and trimmers. It's amazing what folks leave behind when they move out of a rent house.
Thank you 🙏🏻 Chicky for the wonderful and very insightful video…. A lot of what you show are simple but very effective fixes… it all comes down to being familiar with your equipment and properly maintaining it…
Thank you my Stihl FS40 weed trimmer would start great but no power. Thanks to you, I pulled the screen and it was plugged up with carbon. Heated the carbon up and scraped it off and it has lots of power now. You saved me a bundle. Thank you
My weed whip....32cc started losing power and within 3 weeks of use would hardly start anymore. I looked at and cleaned everything except I neglected the muffler. It still has the same problem. You have just given me the last step in getting this beast to chew acres of weeds once again! I'm sure of it! Your videos are a wealth of knowledge and a great time saver and money saver for Johnny and Jenny Homeowner! Thank you for all you do! J Pol.
Hello everyone, thanks so much for watching! Reading through the comments, I think I need to clear a few things up. As I said in the video, Stihl oil is great. I HIGHLY recommend using Stihl oil, especially if you are still in your warranty time frame. Yes, they do offer an extended warranty if you buy their oil, but yes, if you do not have Stihl oil in your machine at the time of needed warranty repair, they can decline to fix it under warranty. It really is on the discretion of the Stihl warranty service dealer. Here is the Stihl warranty so you can see. www.stihlusa.com/WebContent/CMSFileLibrary/downloads/Limited-Warranty-Policy.pdf It really is more of a "how you run your machine" issue. I made this video for people who don't or can't run their units at full throttle. Exhaust clogging does happen quite frequently and I just wanted people to be able to diagnose and fix it themselves so they can get back to trimming and blowing without an expensive shop charge. Yes, all oils will do it eventually, but in my decade of experience, and my shop getting over 2,000 pieces of equipment every year, I see it more with the Stihl oil. No, you are not going to see this issue in a chainsaw that often, because they run at such high rpms they usually don't clog up. Once again, thanks so much for watching! I hope I saved you time, money and frustration in the future!
What's your thoughts/conclusions on AMSOIL Sabre synthetic 2-stroke oil? It claims equal protection when used in power equipment at half to one-third the amount required of other oils, including 2-stroke blends.
Where have you been 💣
@@pancudowny To be honest, I am guessing it is a location thing, but I don't see anyone using it here where I live in Arkansas. I wish I could give you more info, I just don't see it to see what value or problems it has. Thanks for asking though!
working for a stihl dealer we suggest a 6 pack of oil to dbl the warranty .. for warranty issues if they run a machine without oil in the gas mix it is pretty obvious and therefore not covered under warranty ..
@@tomspurrier3325 I work at a dealer as well. This is one of the most common issues we see. STIHL oil is almost 100% the same as every other oil. The issue is is exactly what she said. Government emissions regulations.
We show this to most of our customers as this is considered maintenance by STIHL and we don't want customers having to spend 20 bucks everytime when with a torch and a compressor they could fix this in a minute and be back to work.
Its one of the few downsides of running a quality tool like STIHL. That and customers leaving gas in their tools without using them for months or years at a time are the two biggest issues we see.
After a long time of trouble shooting, I did recognise this exhaust filter/flame arrestor was 100% clogged. I took it out many years ago and all is well. I have had no sparks emitting from the exhaust. My take on it is, if you have such a screen filter regardless of your RPM or oil used, it is just a matter of time and it will get clogged. I use light body SAE automotive oil and no problem. My FS55 is about 20 years old now, but works well, with very good power and acceleration. I don't use the unit often, but when I do, I push the unit long and hard. Thank you Chickanic for highlighting this problem and fix.
Thanks. These tips are super helpful and I swear you have saved me tons of money on prevention rather than repairs. Thanks again. Keep it coming
Just tried this and it worked to absolute perfection......thank your so much!
You are exactly right on your diagnosis you hit it dead on the head finally someone that actually understands about a two-cycle
Outstanding. Such a simple fix and makes perfect sense. I greatly appreciate it.
Another great video. I learn something every time I watch you. I did learn several yrs ago when my back up generator wouldn't start that it was from old gas and ever since I run only ethanol free gas which you can get now at most Sheets stations (the red pump handle). I even run a tank thru my vehicles every once in a while and notice an increase in my mileage. Yes it is pricey but its worth it.
Hi! I can't give you any tools to use but I can say that you floor me with your extensive knowledge of almost any small engine made! I've learned so much watching your videos! I have a stihl chainsaw I use for my firewood and cause of you am not scared of checking it out when it doesn't run as it should. No problems with it yet but when I do I at least have some knowledge of what to look for. Thank you for having a you tube channel that helps out someone like me!!
Very rarely ever replaced the spark arrestor unless damaged. Get the handheld torch out and burn screen until cherry red, blow out with air, and if its still clogged spray screen with penetrating oil and reburn it. It will clean up after that.
This is exactly how we do it in our shop :)
Nice to see a pretty lady that knows what she's talking about I'm tired of these beginner people that heard something once and then want to make a video not knowing a damn thing about what they're talking about
Happens on any two stroke that gets run at low rpm. See it on pumps on wildland fires frequently.
Dip screen in some gas and ignite helps burn off. scrape gently and repeat if necessary. Run high rpm with a load, keeps things working smooth
Yep save the customer a little money
@hondag200 From the empire that the sun never sets.
Great video! I just helped a buddy of mine fix his Stihl BP blower with the same issue in the same manner.... quick & free fix. The advice about running wide open throttle (WOT) I'd spot on for at least a good part of the time. As a former 2 stroke dirt bike rider and racer for years, the advice is the same. To have better and more complete combustion with an oil/gas mixture WOT once in awhile is a must. The smaller the engine the more true this is otherwise expect clogged up spark arrester screens. I've run stihl, husky and homelite 2 stroke power equipment for 45 years and never had this problem, just mix the right ratio and stay away from ethanol/bad gas & don't forget to clean the airfilter once in awhile. Happy motoring!
Yep! Same here
WOW ... funny to find this! I have a 37 year old Echo trimmer (SRM-210AE .. 1985) ...still runs great. I do run it rich (too much oil). Sure enough, about 5 years ago it would not start. Took off the muffler ... found the spark arrestor .... clogged solid. Cleaned it (eventually replaced it when I found one) ... still working great!
My fs 56 has the flat screen. I've learnt so much from you. Thank you so much, Chic. Was hoping that was my problem but I stored my tool improperly and screwed up the carb.
8 years on my stihl chainsaw, trimmer, and leaf blower. All start with two pulls. One with choke on, one to start. No complaints.
Great videos!
A few words about 2 cycle engines..
The cold seizure is when a piston expands unevenly and scores usually on the exhaust side.
The cause is starting a 2 cycle engine and running it at full throttle from the start. The cure is to warm up the engine at idle for a short time before going full throttle.
How long do you let a 2 cycle eng. warm up?
@@johnnellis3025 How I do it, in the summer idle for about 10 seconds then half throttle for another 20.
Chain saws in the winter should be warmed up too before cutting at full throttle. Same for 2 cycle snow blowers. I have 2 cycle engines over 10 years old and never had a problem with piston wear.
I usually start the engine on whatever two stroke equipment that I'm going to work with then lite a Marlboro red short up. When I'm done with my smoke I let it rip and hear the power of a stihl as I get it done. I have equipment going on 10 plus years old. I don't constantly hold the throttle wide open the whole time I'm working but it stays between half on easy tasks and three quarters to full on the thicker or harder stuff. No sense in running a powerful trimmer wide open throttle just to trim between one to three inches off of grass. Now if it's a foot and a half or more of grass and mess then it's wide open and slicing through but that's a pretty good load for it to handle.
@@johnnellis3025 8
Also from running low octane fuel
Great video! I've not had an issue with my chainsaw or weed eater, but thanks to you I'm mixing my own fuel and will know what to do if I start losing power. I usually run things wide open, so I'm hoping to avoid any build-up, but at least now I'll know how to fix it. Thank you, Thank You, THANK YOU!!!
Ty for your smile while explaining,l am not mechanic but I want to try to fix my trimmer that doesn't start,GBY
I could feel the resistance in the engine but the air filter was clean. Your expertise in finding the exhaust filter as the culprit is truly appreciated. Thank you!!!
I am a long time mechanic and most of the time when I check out others sites to see how they approach things its really no different than my own . however I love your videos . you put a down to earth approach on things . Thank you . I look forward to watching more of your vids.
I have a Stihl HS45 hedge trimmer that had a real nasty one that was really clogged up! Took me a while to hit it with carb clean and a brush but once I did that the trimmer ran like a beast! Found it for $20, replaced the filtered and cleaned it and all set and working. Thank you for these videos!
Love your videos and maybe more importantly, your plants and garden! A reflection of who you are...Thank you for taking the time...
I've only managed to see a couple of your videos but in those two videos it just confirms, that if a lady mechanic is in the business, she definitely knows what she is doing and what she is talking about. They take it upon themselves to be better than any of the rest.
Not true at all.
Thank you so much for the information,my weed trimmer was acting like it had lost most of its power. After watching your video I did what you recommended and wow! It's now running like new, P.S. love your video's 😎
You were right, of course. Lugged my trimmer down, knew it was bad, but...just...wanted...to...finish. Would not start again, fresh gas, new plug, figured I had burned it up, bought another, kept the old one.Took your lesson, fixed it, thanks again. (Good news about your future, Old mechanics never die, They just lose their bearings)
Mine dropped power big time - will check this out - thank you !!! And yep, always run on Stihl oil - 15 years in !!
Thank you for a very honest review and tip. A couple of years ago my neighbor brought his Tanaka 2 stroke trimmer over for me to look at because of low power. He tended to put too much oil in the gas hoping to make the trimmer last longer and the spark arrestor screen was almost completely clogged. So I used a propane torch and heated the screen cherry red. The carbon burned off in fiery sparks and when the screen cooled off it looked brand new. Problem solved. However, your videos reminded me that I too have a Stihl "hurricane" chainsaw that has been sitting in the garage for a couple of years and even though my normal winterizing procedure is to empty the fuel tank and run the engine until it dies the fuel lines and diaphragm are probably hard as rock. So with insight from your videos I will order an OEM carb kit and save myself time and frustration. Thanks again.
Tell your friend that the evaporative effect of the fuel hitting the piston actually cools the engine. The oil is lubricant. But to much oil will not make it run cooler, just use more fuel and make more smoke.
With alkylate gasoline there's no need to winterize. It also burns cleaner and does not smell.
Good tip. It is exactly what I found wrong with my fathers when he gave it to me to fix. I have been a autotech for 33 years and small engines are not my thing but the relatives keep me busy. Now I know how he does this. As my Stihls never do.
Thanks for the info, just bought a new styll trimmer and got a year extra warranty cause I bought their oil, i will do what you said, i watch your show all the time and love it.
You are such an inspiration for all of us mountain women
Thank you for this it’s very helpful.
I’ve had my Echo for at least 26 years (sentimental now at this point) I just put a new carburetor on it and runs great but I can’t wait to clean the exhaust screen!
Very good vid. When I think 2 stroke I think RPM's
No problems with any of my saws, trimmers, etc.
I keep the screen in. I started a fire once on a friends property with a chainsaw without a screen.
Long time ago in the early 80's, I was a bike mech. Two stroke engines were used in small displacement scooters. The "muffler/stinger" was one unit and would clog with carbon. No power, so we would remove the unit, start a little hot fire and throw it in & let it burn til the carbon was gone. A fresh coat of hi-heat black and customers were happy
Trust folks like you much more then big corporations THANK YOU love ❤ your channel
The spark arrestor on my generator was clogged like the one you showed on the video. Just out of curiosity, I sprayed it with a generic glass cleaner containing ammonia and brushed it with an old toothbrush. I rinsed it off with water and was shocked at how well it worked. It looked almost like a new part. I don't know if it was the ammonia or something else in the glass cleaner, but it dissolved the carbon like it was nothing.
Like you, I love Echo PBG. It smells better than Red Armor and produces less smoke, even at 40:1. I have switched over to it from Red Armor after using Red Armor for a year to clean up my saws after running Stihl Ultra for quite a few years. You are perfectly right about Stihl Ultra and how will block up spark arrestors. Now, I don’t have to burn off spark arrestors, as I had to when running Stihl Ultra.normally, my torch will burn off the carbon as I heat it up to orange color temperature. After it cools off I put it back on my equipment.
i am going to check my weed whacker this afternoon. been struggling for years to get it running right, thank you so much!!!
Hey Chickanic, thanks for the vid. I was having exactly the problems you describe with my FS200 trimmer, followed your tips, problems solved! Thanks Again!
I pulled the spark arresting out of my saw the second time I used it. Runs great ever since.
I’ve done that with every chainsaw l bought, since 1987. The only time l re-install the spark arrestor is when cutting timber in summertime, to avoid the possibility of starting a fire.
I pulled the screen out my cheap home light and I’m happy. Gotta now go and do that to all my stuff. Couple mowers, couple trimmer, couple edgers.
I have the same weed trimmer and so far no issues except it shakes more than echo and I use high test gasoline starts 1st or 3rd pull
If you get caught without a spark arrestor in the national forest they may take your saw or fine you. 🙂
@@baldeagle242 No, you can cut downed trees.
Random things you didn’t know you needed to know....thank you, I’m going to check my trimmer tomorrow
Thanks so much for your valuable information. If this is your back yard, it looks like you are equally talented in gardening, as you are in small engine repairs.
You do an awesome job. I have learned a lot from your videos. You articulate the information very well. Thank you for your videos.
I had my Stihl chainsaw screen clog over a few years ago. I hadn't seen your vid, but guessed it was unburned oil and fuel so I blasted it with a propane torch. Then I used a brass wire brush to finish the job. Clean as a whistle after that!
Great vid, looking forward to more!
Excellent commentary! Clear and you stayed on subject! I usually carry my equipment in to our local and they clean that exhaust port for a modest fee plus check ‘er out before I start my yard work for the season. Thanks for the tip on the Echo oil too!!
Echo oil is great. Cheaper too.
You have great videos I usually watch Tyral fixes all and small eng saloon . Your programs are just as good . If you don't shake up the fuel every time you add some it won't be mixed and the stihl saw won't rev up .
Well done and clear. I'm sure that will help a lot of people. Thanks for your work on this.
I love all my Stihl trimmers, power washer and chain saws and have a great dealer and repair location. Good detail to know that everything should be run full throttle. I did trade in all my gas chain saws for a battery powered one because I can't get the gas ones started because I leave them sitting for long periods between use. I also really like Chickanic. I'm 68 and grew up in a time and place in which girls and women were treated as incapable of doing anything like this. I am always deeply affected when I see women proving them wrong, and, these days seems like I'm the only one still marveling at it. Now it has become obvious to everyone.
Super video, thanks.
We’ve owned a landscape maintenance business since 2008. We have very few Stihl products, a couple nice hedge trimmers and a small rototiller and that’s it. We run Echo’s and always have. They have been bulletproof. We have a string trimmer that’s been in service since 2010. Our crews look strange cause every other company in town runs Stihl’s. I laugh all the way to the bank.
2010, that's cute. I've been using my residential grade Stihl (FS55) since 2002 for 6-8 yards a week.
A big thanks. Stihl oil etc per dealer instructions and I had a totally clogged spark arrestor. Disassembled and cleaned the screen. Now it works great!!
Thank you for the vid. I have a sthil ms193. I could get it to idle & died soon as i hit the throttle. I changes the primmer, spark plug, fuel lines, cleaned out fuel tank & carb & still had same problem. I was about to order new carb when i seen this vid. I pulled the muffler & the piston looked good. I pulled the screen & cleaned the carbon out of the screen & muffler. It's running great now, i never thought of the muffler being plugged up.
Thanks Chicanic, I live in Australia and this very same thing happened to my FS90 recently. In fairness my dealer mechanic showed me the filter and told me to run it at full throttle to avoid clogging the gauze.
I appreciate your tip too on the Echo oil, I'm not sure if we have that brand here but I'll endeavour to find out.
Not that easy to find Echo lubricants here in Aus, Penrite 2 stroke oil is easy to find at Repco, Autobarn, Supercheap though. Been using Penrite for many years now.
I have used Stihl equipment for nearly 25 years - string trimmers, hedge clippers (HS80), edger (FC85), hand blower (BG86), and chain saw (limited use). I have gone through many string trimmers - FS85, FS94r, as well as BG86. Cleaning out the exhaust screen and port is just routine maintenance. There is nothing unique in this task.
For the last 20 years, I've used Amsoil, at about 50:1. The FC85 has ran for more than 15 years. But the trimmers run for 2-4 years - engines lock up. The advise of running WOT is important. I think it may be the key to the FC85 longevity. Edging is always WOT (also use it with a 22" hedge clipper attachment). I used my FS94r to trim out 5-7 lawns per day.
Many of the comments here speak about "2 cycle." Many of the Stihl family are 4 cycle. The issue is not 2 or 4 cycle, rather the lubrication mechanism - sump vs. vapor. My trimmers have been 4 cycle for years and I have no problem. One valve adjustment after about 50 hours and never again. The major problem is carb diaphragm failures. Apparently, the ethanol degrades them. A rebuild is simple. Even new ones are not very expensive.
Thank you for that detailed informative response bud.
I only use 100% gas, no ethanol. I've never had a problem, and this is over 20 years of use.
@@btolich I don't know where to buy ethanol-free gasoline. I do buy Premium grade gas for all Stihl gear. Is it better than Regular? Dunno ... I have no statistics to prove one way or another. Many years ago, somebody on a Forum strongly encouraged the hand-held equipment to burn Premium.
@@rightsideofthegrass8114 Bummer! Even though you're using premium grade, it still has ethanol, and that degrades the rubber components of the small engines. The octane rating merely has to do with how much compression the fuel can withstand before detonation. Premium is typically used in vehicles with high compression ratios. Small engines don't generally have high enough compression ratios to warrant the use of premium fuel.
@@btolich We have ethanol free premium in Canada, Esso Synergy Supreme 91 octane for example. Testing for ethanol in gasoline is simple. Project Farm explains it better than I can.

There's more than 1 secret to Stihl's Silver oil and it will prevent clogged up exhaust screens. I've been using Stihl machines since 2000. I did at first have the clogging up screen problem. I said something to my dealer about it. He said that since Stihl's silver is synthetic that I can mix it at 80:1 and he would personally guarantee me that I would not have any oil related problems going forward. That was 22 years ago and I haven't had one single oil related problem, from clogged screens and ports to abnormal wear and tear and the piston, rings, or cylinders. The oldest piece of Stihl I have still in service is a 2003 FS80 powerhead. Next up is a 2007 BR600. My newest is a FS70R grass trimmer. I've had other Stihl tools that I've sold and as far as I know, they're still running to this day. You can also mix Amsoil at 80:1 too. I have had to make other repairs such as a new carb here and there, or a new coil, but the basic machines are still strong and ready to go to work every day.
Great info I love my Stihl equipment and the oil and yes I do run them wide open all the time.
Great info.
I've always used Yamalube 2r in every 2-stroke I've ever owned. My Echo trimmer is 16 years old, and still starts on the first pull. I have a huge yard, and go through almost a full tank every time I use it.
Yeah man Yama. lube is the one to use
I would always recommend 2R to customers who came through the shop I worked at. or Motorex. I also use their Waverunner oil in my Waverunner 500. their Yamabond is the best stuff on the market too
The motorcycle industry is where to look for the correct 2 stroke info. We have been running clean burning oil for decades that promote reliability and performance. When someone says "no you can't run your machine without the spark arrestor " then winks at you, they really mean the opposite. Spark arrestor are mandatory for motorcycle racing on state and federal property. We always cut the screens out and replace it with a cotter pin so when tech inspection sticks a probe in the exhaust it stops at the cotter pin. Passes tech every time.
Hi.At the start of your vid I was about to jump on you.I have been a Stihl master tech for 25 years.I do not find a lot of diff in most oils and germany has masterd it.Opti or chinese synthectics are the only ones that will void a warranty.That being said you gave a great demo and covered most of the problems,the costomer being #one.On my bench grinder I replaced the wire brush with A brass one only takes 30seconds to clean a screen.Just for shits and giggles I own many Stihl,Husky and Echo products.All are run on the cheapest gas possiple.Kept inside and run at least once a month.I have not needed to do a carb job in ten years.Again costomer being the problem.Well done.
Thank you! I do the same with the cheap gas, although I do use ethanol shield. I only use my 20 yr old BR 400 a couple times a year, and it starts every time. It was one of the best light blowers ever made in my book. Thanks for watching!
Stihl doesn’t have master techs. They have 3 Levels of expertise.
Master Tech?? Lol
And HeMan is the Master of the Universe 🤭🤗🤣
@@THEMOWERMEDIC1 Correct
Interesting, I've been told by 4 seperate Stihl dealers that unless I use either Stihl motomix, Aspen or at the very least Stihl super 2 stroke oil they won't honour the warranty on fuel related issues. They say Stihl original oil is just as harmful to the newer machines that even that will void warranty. Who's telling the truth here?
I definitely enjoy your input I've learned something each and every time And I do believe you're very honest and straightforward . Keep up a good work I'll keep watching :)
Mack, not Clara, sorry...
THANK YOU so
Much for this info that got my trimmer going!
As a Stihl professional, I can tell you that every other maintenance of your machine it would be good to use the decarbonizer to help prevent any such buildup! As soon as she said she wasn’t paid I knew she had a biased that was confirmed when she said she was an echo dealer! lol
I’ve run my Echo 770-T in my lawn business since 2016. Never used or needed a decarbonizer. I did remove the spark arrester but otherwise it’s stock with no other mods. Still fires right up and has full power. It also starts much easier than my new Stihl backpack blower. I use the Quicksilver oil from Walmart.
Recently purchased a Stihl trimmer the sales person never offered or mentioned any specific oil for this trimmer.
@@fivespeed3026 Exactly... You never needed it because you removed the spark arrester so it doesnt get clogged with carbon! lol Not saying it will happen but its a potential fire hazard for grass as well as yourself!
@@monti409 Apparently the sales person was poorly trained as purchasing a 6pack of the premium oil would have doubled your warranty... but from experience I can tell you that you wouldn't need that warranty anyways!
Thanks for the honest advice! Most folks don't know that checking the screen should be part of their regular maintenance schedule on their tools. You just saved people a lot of money!
It’s in the manual
I have a small gardening/yard maintenance business, and the only power equipment I own is Stihl. I own 4 hedge trimmers: My first one is an HS45 (the best of the bunch engine wise), an HS56, an HS56C, and a brand new HS82T. The HS56 series of trimmers are CONSTANTLY in the shop for a loss of power or for high Rev spasms. Just today, my brand new $800 HS82T is now doing the same thing as the others, and I can't believe it!🤯
I also own basically every other piece of Stihl equipment that there is to own, and most of everything else works great. No complaints. So I believe it has something to do with how the hedge trimmer motors are built.
I use high test gasoline with Stihl oil... I will purchase Ecko oil and see if I notice a difference.
Thanks for this video!
Thanks so much! Very useful information since I have 3 Stihl products and bucket loads of their oil in house.
I have a steel FS 70 weed trimmer noticed I was getting all the residue around the muffler pulled my screen and cleaned it but did not realize I need to run at wide open throttle thank you for the comment
the only time you shouldnt run a machine at full throttle is when you're trimmin around delicate things otherwise always run it full throttle
I passed on the Stihl oil and went with my trusty Amsoil Saber at 100:1 on my FC56. Runs great, had it 6 years and I cleaned the arrester two years ago and it still wasn’t clogged, just a small amount of carbon.
I have been running Amsoil 100:1 with all my two stroke engines with 93 octane non ethanol for many many years with no problems whatsoever!!
Ha!! when my Stihl MS 192 C chainsaw developed this issue, the first thing tech did was remove screen and tossed it away. My new MS 194 C-E just had a hesitation issue and they replaced the spark plug and told me my gas was old and brown?!?! Say what? That was a fresh mixed batch using their oil they sent home with me.
keep up the great work!!
I’ve been looking at the FS 131… Thank you so much for the helpful tip with running at full throttle! Great advice ☺️
Even ran full throttle 90% of the time the screens still clog, cleaning the screens is part of general maintenance. 30 seconds and a mapp gas torch not much more then cleaning a spark plug
Just take it off.
@@rk22cc Yeah great Idea let dirt dobbers into the engine.
You work for the EPA right. Exhaust port"………
@@rk22cc No just watch the other video she posted.
I have been weedeating about 5 acres around my home every year for about 40 years and I use older shindaiwa c35 machines, I don’t run full out because I take it all the way down to the dirt and if you are full throttle you get peppered with small rocks consistently, my spark arrestor was plugging up quite frequent so I started using 92 octane fuel and ever since then I have not had to clean the screen once, but I do inspect it once a year.
Just spent $350 on a stihl brush cutter and this is something that should have been in the 90 some-odd page, 60 different languages, damn near useless owners manual....so thanks for the tip
This is no tip, its operator error for 1, and any oil clogs the screen if u run low rpm. Also stihl gives u 2yr warranty if u buy a 6 pack of platinum oil when u buy whatever, they don't make u buy they're oil
@@kwmiked it is a tip since the manual doesn’t mention if you don’t run full throttle you clog the screen my point was that “tip” was better than any of the information the manual had to offer. And yeah they offer the extra year for a six pack of oil or a $38 gal of pre mixed gas but that has nothing to do with the “tip” or as you like to call it user error for not following said tip
Great video presentation and informative. In Portugal there are days when (s)trimmers are legally required to be fitted when used in forest areas, but are not fitted or available to purchase from Stihl in Europe.
My first motorcycle used 16 to one part oil, mid 60s and I always used regular car engine oil. No problems with that. No so with Yamaha 350 twin mid 70s, revs had to be kept up or the plugs would oil up and the only way to get the bike going was to change the plugs and heat up the removed plugs on the gas stove ready for next time.😂
Interesting video and your findings. I have a Stihl and just because of the way I clear the yard, almost always use it at full Throttle. Likely have no carbon build up. But haven't actually checked. My trimmer is years old and has an Echo line feeder. I have gone through 4 or 5 of them already, but they are not pricey and they certainly make trimming work much easier. I always keep 2 spare trimmers in case something happens to one, I still have a spare. Great video.
