This video show the repair of a Stihl SH86C Leaf Blower. I tried a few things to repair this blower then the lights came (in my brain) on and I got it.
Your 5 year old video is still helping people today. My blower was doing the same as yours. My first thought was the spark plug . Changed it and still ran bad. After watching this video...Sure enough my screen was stopped up too. Cleaned it and my blower ran perfect. I've forgotten it was supposed to have this much power. I'm going to check my Stihl weed eater and edger tomorrow. I will definitely make this part of my maintenance on my equipment for now on.
Thanks
You made my day. I love it when these old videos help folks.
Good video. For future reference, there's no need to scrub the arrester, or blow through it. Simply heat it until it glows orange all the way around. Once cooled, it'll be clean as a whistle. Extremely common in all the Stihl handhelds because users run them at idle so much. They clog easily when used that way, because the exhaust system never gets hot enough to burn off all that carbon/fuel residue. Their exhaust ports will usually also be partially clogged.
+austinado16 Thanks
Kudos to you my friend, just checked my spark arrestor and it was completely blocked. On the down side now my wife knows its working so no new toy!
Good for you you got it!!!!
Bruce Pender c Ou
scotta74 try hitting her.
Like you I cleaned the air cleaner, checked the spark plug, changed the fuel for fresh two stroke, I ran the engine and tried to adjust the mixture all without success. next stop $150 service at the local lawnmower shop.
After watching your video went back to the workshop and removed the spark arrestor bingo completely blocked.
I used the wire wheel on my 8 inch bench grinder to clean the residue off the arrestor and it now runs flat out . Best blow job I ever had. Saved a $150 to.
I am so happy you fixed it.
I've learnd over the years with 2 cycle engines to check the spark arrest first thing. More often than not, it's a clogged screen. Great catch and repair Bruce!! Cheers my Friend!! Zip~
Wonderful wonderful video..I am not an engine guy but I did have a leaf blower that bogged down
..I did what Bruce said..cleaned exhaust filter( just unscrewed it ..did not have to take the whole filter system off) with starter spray to get rid of the oil and sludge and it kicked right away. Great video
So cool you fixed it.
I have a BR200, small backpack model, about 2 1/2 years old. It developed this exact problem this spring. I was expecting it to be a dirty carb issue but luckily found this video from Bruce. The spark arrestor is accessible through the opening in the plastic casing with a 15mm socket wrench, so no need for further disassembly. It was clogged, I heated it with a torch turning the crud to ash, then blew it clear (compressed air not needed). I can't say that I always used the Stihl oil, but will for the next 12 months and check it again.
Yes i went to far before i found the problem. that happens though.
My BG86C is about 2 years old and started running terribly...then it finally died today...I found your video and removed the spark arrestor and it ran like brand new again...the spark arrestor is taking a bath in brake cleaner right now while I do other things...will see how much it loosens before trying the torch method...thank you very much for the helpful tip today!
That is great.. You made my day
God bless you Bruce...I just did it at the same time with you....and....YES!!! IT'S BACK TO LIFE!!! Thanks for your help!!! All the best!!!
That is cool. Thanks
Thanks Bruce! I have a BR350 backpack blower that started running poorly. Better than the one you started with, but bad nonetheless. After trying a carb clean and breaking my starter in the process, I was just about the head to the dealer when I found your video. Fifteen minutes later I was back in business and running better than ever!!!
GREAT You fixed it. Usually with Stihl products the problem is a minor one. (but not always of course)
big help, thanks. I replaced the spark plug, cleaned the air filter, couldn't figure it out. You just saved me some money since it won't have to go into the shop now. Appreciate it
That is great. I am happy you fixed it.
you just saved some money!
I had problems with my blower not running right - actually, it ran very poorly! Checking the spark arrest was something I never thought of! I checked mine and found it completely plugged! I proceeded to clean it and restarted the blower to find an excellent running blower.Thanks for making the video! Love it! Thanks again!
This is why I got onto You Tube Thank You !!!!!!
I have a new BR450 blower that started running crappy after only 3 months even when using Stihl oil and premium gas. Tried everything. After seeing the video, pulled out the spark arrester and guess what, it was plugged. Thanks for the help.
I am so happy you fixed it.
Thank you sir for the great video. I checked the spark arrestor first thing and it was totally plugged. I cleaned it and saved myself from having to buy a new blower.
You made my day Thanks Todd
I’d spent the last couple of days trying to fix my blower until coming across your utube footage. I’ve followed out your steps and my blower now works perfectly. Thank you Bruce. Phil
You are so welcome. This is why i am ion You Tube
You’re stihl the man years later! Plugged right up, had mine running in 10 minutes
Perfect. Good for you
Just viewed your video. Had my blower worked on not too long ago and it ran somewhat better. They said it was the gas but I knew it wasn’t the problem. Waste of money. They should have known to check that.
Your video was exactly my issue and when I went to start it I could tell within five seconds it was fixed. Very simple fix!! Going to your videos first every time I have a problem with something from now on. Thanks many times over!!
Thanks Joey. that means a lot.
Posted over 4 years ago! Thanks! You fixed my BG56C!!! Yip, plugged spark arrestor. Runs like new. It probably doesn't help that I add a little (?!?) extra oil to the gas. But, I go by the philosophy "if a little is good then a lot..."
You fixed it not me. Go 45 to 1 on the mix. Just a hint. 50-1 is the manual.
Great info, got mine working as well plugged up muffler. I don't have a torch though. So what I did was attached the filter to a drill and used a wire brush while it turned at high speed. Worked like a charm, thanks.
Good for you.
I saw your video, cause my Stihl leaf blower was doing the same thing. I did the same thing you did and got my blower working again. Awesome video. Thanks much, Bruce.
Glad it helped. You made my day, as my channel was made to help folks like you.
Thanks!! You just saved me a trip to the repair shop. My backpack model was doing the same thing. Pulled the arrested and cleaned it and Viola! Runs like a champ.
Good for you.
Thanks for saving me alot of time and money. My and my stepdads Stihl weedeaters were doing the same thing, easy fix! Last time mine was acting this way I found a dirt dobber had clogged my exhaust, same symptoms but no dobber nest. Just had to look a little deeper with a 15mm socket
Very good so glad you found it.
I was getting ready to start fiddling with the carb, and 98% sure I was going to buy a new blower tomorrow. Nope, not anymore. Thank you sir!
You are welcome.
I work on sooo many Stihl blowers, i can hear a plugged spark arrestor a mile away. I knew what it was 30 seconds into the video. Nice work. Good to verify everything else is kosher.
Yes Sometimes the person fixing it just has to go through the process. I show everything i do.
Brilliant! 10 mins saved me $50+ in repairs...Completely solved my issue...Thank you!
That is cool
Un gros Merci pour ce vidéo!! Après plusieurs heures d'ouvrage sur cette machine, et sans résultat, mon chum a été enchanté de trouver enfin la solution grâce à vous.
Vous êtes tellement les bienvenus, Merci
Had a Stihl serviceman told me that all this brand has this problem at one time or another if it runs at low speeds . The low speeds causes this problem- and the propane torch will fix it and blow off the ash after it cools or lightly wire brush it . Thanks God for utube videos Bruce , and thank you too .
Thanks for the great comment Marshall
Another great video, and reminder to check the spark aresstor screen More often than not, when there a clogged spark aresstor screen, the back pressue from the exhaust will go thru the carb, and end up dirting the air filter. Sometimes when diagnosing this issue, a dirty air filter and the smell test will lead you to the spark aresstor screen
Right thanks a lot.
You, sir, saved me a lot of time and frustration. I thought the carb was the problem, but runs like new now. Thank you much!!
Good for you you fixed it.
I had the same problem happen to mine, happened a bit over a few years until I got fed up and decided to cut the spark arrestor off to exhaust tip, what a huge improvement. I live in the suburbia so no need to worry about dry bushy areas to set fire to, but got a spare spark arrestor in case. Even with the Stihl HP Ultra oil mixed properly it still clogs up, that's why I just cut it off, but thanks for showing me an easy way to unclog it so I know how to unclog the new one.
Great stuff. Thanks for the input
Bruce you saved me a carburetor job, your video was fallowed to the tee and solved my problem Thank You
+Shirley Gagnon Good for you. This is why I make them. Thank you and congrats for fixing it yourself.
Thanks for this tutorial. I have a similar model with the same problem. I've basically rebuilt the thing but to no avail. I never thought to check the muffler!
Well I did what you did and checked the muffler last.
Thanks Bruce. Your video was spot on. I have The same make and model as yours and the same problem. I cleaned out the exhaust like you did and my machine went from boging out to blowing like a hurricane. Well done
This is why I got onto You Tube. To pay it forward. Thanks for making my day.
Hey Bruce just wanted to thank for the video on repairing a bogged leaf blower. I thought that I would have to go to a great deal more work and expense but after following your video to clean the spark arrestor it runs great.
Good for you Mel
Bought the BG50 yesterday. Thanks for the vid! Looking at many years of a clean yard..
I sweep the shop floor with mine.
Bruce Pender, Great video. You saved us from bringing it into a specialist. Thank you from Australia!
+DatJD,ED,M channel You are welcome from Canada (EH)
Good catch Bruce!! It isn't tough to overlook something like that, most of the time we start a repair with tunnel vision!! I never would have checked the exhaust!!☺
805ROADKING Thanks.
I would like to thank you my friend was on my way to Ag-Pro to buy me a new carburetor when I decided to stop and watch TH-cam first within 10 minutes my blower was running better than new thank you
That is so cool. I replied to the other comment too. Thanks
Thanks for sharing. Was exactly the problem with my Stihl FS 85 Brush Saw. Saved me paying a shop rate. Thanks very much!
You are welcome thanks for watching.
Thanks for posting. Since I live in a wet are inside a neighborhood, I cut the screen off the nozzle using a die grinder cut off saw. The saw is slightly louder with the nozzle left out, but pretty close to stock noise with the nozzle with no screen.
Great. You got it.
Thank you, Thank you, Thank you Bruce! I've got a Echo PB 230LN hand held blower that I put up 9 months ago when it started to loose power and bought a PB 250 LN. Today, it wouldn't even start. I always have Echo equipment, and have always checked the spark arrestors and I usually just find blackened screen at the worst. Plus I knew I had already removed the screen on this a couple of years ago. I changed the plug, fuel filter and lines and carburetor and it still was low on power. I was happy it started, but was ready to put it on Craigslist and get me something better then the PB 250. I just proves it pays to check out TH-cam for some helpful hints.
Thank you for watching!!!
I always learn something new from your amazing skills, thank you for posting these brilliant videos.
My pleasure!
Can't thank you enough Bruce. My problem was solved. I owe you are beer! Cheers from Adelaide , Australia.
that made it easy for me!!!! Thanks for watching.
That did it...but all you need is to spray some carb cleaner in it , wire brush (might not have even been necessary) just took a cloth, small screwdriver, cleaned it out,,,it has never blow this hard....wow...thank you so much
Good for you.
thank you so much for posting this awesome video .it took me less than 5 minutes to get mine working after watching this video
Bruce you just saved me lots of $$$ and time following your video Thanks so much You are the God of Stihl
Well I don't think so but thanks and I am happy you fixed it.
Mine has been doing the same thing and I have done everything but this to get her going today. I said "I know someone has a video on youtube" and yours was the first I pulled up. Thank you so much for posting this Bruce! I call this my TH-cam Collage. LOL.
+Elaine H (Mamaknock Redoubt) I am happy you fixed it.
Bruce Pender
Well this is the 16th and after cleaning the spark arrested the other day it needed alittle more help. Re-built carb,replaced plug, gas filter and cleaned out stopped up fuel pump gunk. She's running strong and like brand new now. Not bad for 9 yrs old and I cleared off front lawn & found my driveway again in just a few mins. Plus I only spent $20 bucks. (I would have had her done before now but took the wkend off for a little B-day road trip lol)
Mine bogs down after about 5 minutes, I'll take a look at it sometime this weekend. Ohh by the way Bruce careful using latex gloves with that blow torch, they could ignite with any sparks that get on them 🔥
Right
You got it! 2 minute fix. My Stihl SH55 has done a ton of work both blowing and vaccing and it's 10 years old!
2minutes in a video 2 hours without editing haha
ALl the times I've repaired these machines, it's never been the spark arrestor....but it was this time. Thanks for pointing me in that direction....
Yes they plug up It is time to check mine. this is an older video. Please can you tell me if the date i made it is visible????
@@BrucesShop It's visible in the text....
@@jokearrow Thanks Joe
Very common problem with Stihl. First thing you should look for when servicing or troubleshooting. High quality oils and fresh/treated fuel will buy you the most time with cleaning the spark arrestors. :-)
2 years ago I bought a new Troy Bill 4 stroke backpack blower, from the moment I bought it, it didn’t run right. Last month it stopped working so I cleaned the carb, replaced the fuel filter and the purge bulb. It still ran bad so I checked the spark arrestor and it was clean, I decided to remove the spark arrestor and it ran better than when it was new.
Too cool
Also the choke valve inside the air filter element can cause a bog or a flooded running condition. Its mostly on the chain saw side you see this... Good job Bruce...
***** Yes those plastic chokes
I've got a brand new one and it bogs down before it warms up that people at the store said that was normal but once it's warmed up it doesn't bog down anymore
that's normal for 2 strokes they will be a bit boggy when warming up but if it goes away once warmed up you should be good
Thank you for sharing that spark arrester tip.
I have a dead 024 that showed those “laggy” symptoms before it would only idle. I’ll go and try to resuscitate it.
And a hello from Brighton UK

Hello from canada
This was exactly my problem. Thanks Bruce, use saved me a ton of money in repairs or a new machine. Now i wonder if this isn't the problem with my weed whacker and chainsaw. Too bad they arent as easy to get to or removable. Thanks again. Good job on the video by the way but you really should have a camera man 😉
+Vidvertise Good for you. It is fixed!!!
I had a makita blower same symptoms ,I tried everything but the exhaust. Cheers Bruce.
Did that do it
Sure did you a legend.Ive been watching your TH-cam videos for a while now and it's amazing how much you teach people.Thank you.
Thanks! We have a stihl backpack blower that's bogging down. Air and fuel filters are okay. We will try this right now.
Good luck on that!
It worked! Thanks!
Cool
Use some anti sieze compound upon reassembly so next time it comes apart more easily... Although it was not difficult , anti sieze can be a time saver and parts life extender...
***** You are right. I should have put some on
@@BrucesShop why, the heat of the exhaust will burn it off in minutes
Thank you. This was a great video. I ended up using an old toothbrush to clean the filter. It ran very well after that.
What ever it takes to get the job done.
Just finished a clean out on mine. These things are designed to rut HOT. Too much idling and/or bad fuel and you have a the perfect storm.
Thanks for the comment
Great video, should always coat everything with anti-seize on re-assembly. Exhaust parts are known for welding themselves together over time, anti-seize is the answer.
I usually use it but it came out the first time and my mind was on the prize of fixing it. You are right.
I can't get my arrest or unscrewed! Tried PB blaster...not sure what to do ???
That is the proper way to do itbesides buying a new one you could always take a screwdriver through it wouldn't even have to take off the muffler but that is great!!
Right. We have a lot of fires here so i kept it stock. I may not make a difference though as I am in the city LOL
Im have sh 86 for like 4 years and it never ever get a sigle problem its not cheap at alll compere to other brands but it a nice peace of tool than never fail and if it do it cheap to fix 💪💪
YES!!!!!!! thank you. i tried everything else. you just saved me the cost of a new one.
Thanks so much for the positive comment!!!
Awesome job ....the way you did it is the exact same way I do it ....great easy fix....oh and I finally got a lift table for my shop ....love it!!!!
knighthawk86855 I remember that. Good for you. What did you get?Bruce
Harbor ⚓ freight tools one.. Very nicely built once I made my modifications to it! I use it to bring the mower up to my work table then transfer it, it works very well!
Better for the knees eh!!!
Bruce
Thanks Bruce, you nailed it. Totally fixed my problem.
Well that is so cool
You just saved me $40 I was about to order a new carb. Thanks
Good for you Thanks for watching.
Great video and even better advice. My Stihl 86C runs like a top! Thank you.
Thank you for watvhing!!
The best thing you can do with any 2-stroke is sell it and buy a 4-stroke! I bought a Honda blower and it starts 1 pull every time. My Stihl FS45 is nothing but trouble and has been since the day I bought it!
You are right. I agree 100% but I try to fix what comes it. Thanks for the comment I really appreciate it.
all you need to do is get them tuned right. I have had more trouble with 4 strokes then 2 strokes as long as you know how to tinker a bit. (Its not rocket science)
I just picked up a free stihl blower , hopefully this will fix it
I love the F word Free!!!
Thanks , I really appreciate it
Good luck on repairing it. Start simple as in this video.
Good catch DR.Pender i was thinking dirty screen in carb!
mildbull2000 you got it :-)
You just saved me about 100 bucks! Thanks!
This is why I got on to You Tube was to help people fix things.
I bought that same blower new and the first thing I did was to remove the spark arrestor, I do that to all my two smoke equipment.
I understand. We live in the west with high wildfire potential. I leave them in them because I don't know what the owner of the unit it is doing.
hi bruce, good lesson. something i noticed and i'm not sure if it was brought up in another comment. i would suggest not using your driver to start screws like you did on the muffler. you're working on aluminum.
I get that. There is a feel. I don't do it on plastic.
Its hard to Believe but I have a Sthil Bg 55 that I bought almost 9 yrs ago its bogs slightly when its fully warmed up but runs good at full throttle I took out the spark arrestor thinking it was clogged after almost 9 yrs and to my amazement it looked brand new I credit it to Sthil HP oil (silver bottle ) I have been running it in my Echo SRM 225 and it runs great I used to use Echo brand oil and it was hard to start and always had that black runny oil coming out of the muffler but with the Sthil oil in my Saws Blowers and Weed Wackers they start much better and the Throttle response is improved . but on most 2cycle engines this is a common problem having the spark arrestor clogging . Great Video Bruce Pointing out this Problem most people would start adjusting the carb when its not the problem
Thanks. I have been using a regular 2 stroke oil not Stihl. I do have some Sthil oil and will try that in my Stihl blower. It is a 3 pull start.
Thank you for this Great Video mate ! Very helpful
I am happy it helped.
Bruce you didn't have to take off the Orange cover. You can just take the spark arrestor out and clean it then put it back in. Also you should start the unit back up and see if it's the carburetor.
I learned that half way through. I also did a test run at the end. Appreciate the comments
Great info Bruce! I have a sthil blower that has the same issue, I'll give that a try.
You may have saved me a ton of time...thank you Sr!
Well you made my day good luck fixing it.
It worked! runs like a champ!
Great.
I've had the same thing happen to my BG 86 a couple times using Stihl oil. It's a 5 minute fix with a wire brush and some carb cleaner but still frustrating. What's the real danger of just pulling the spark arrestor on this unit?
Otherwise it's a great blower and is pretty strong once warmed up.
I know people who do that.
Thanks for that video Bruce just bought a new one so looking at tips on fixing problems
Fae Jimmy in Scotland
I love mine I use it to "sweep" out the shop .
Hi Bruce. Easy to say, but don't stress over comments that come from people who generally have no idea. Keyboard warriors who's sole purpose is, to upset and to cause grief. The VAST MAJORITY of us enjoy and learn from your excellent videos. Could I do what you do for 400+ vids?? NO WAY. Kudo's and just keep doing them the way you are. I for one enjoy my BTHV1( no take 2 on YT/a handyman never does the same thing twice[ hope I got that right] ) fix every week, always a highlight. Just a wee small request though, if you ever find time, would it be possible to do a short vid of a minute or two, for a vid tour of Red Deer please. Judging from your RD Run vids, its a beautiful place.
Cheers and many thanks from Downunder again,
Mike.
Yes it is my home. Wow I thank you for your wonderful comment.
Well this was helpful had mine running like new in 5 min thanks👍
Glad it helped
Thanks very much for the great demonstration Bruce. I think this is my problem. :)
kev smith It can be common
Thanks so much mate I'm sure you just saved me a few bucks.
good for you
Great video I need to service my sh86 too as it was a bit boggy. Very helpful
+Matthew Lewis Thanks for watching.
I have a similar problem. I bought a blower that wouldn't start. replaced fuel lines, carb, plug, and fuel filter, but it's bogging down. I just placed an order for a new muffler. my blower doesn't allow you to get to the spark arrestor. thanks for the vid.
I am sure there is a You Tube on it somewhere. Give it a try. Or if you figure it out make a video. How about that.
Bruce Pender thanks Bruce. it's a bvm200vs blower. I downloaded the manuel, but it doesn't say how to service the muffler. I've taken it apart but I don't see anything to service. I'll keep looking and let you know what I find. great videos.
Worked like a charm!! Thank You Sir!
Fun
I never would have thought to check that! Like that nice clean garage! Do all blowers, (mine is a cheap Home Depot) back pack one, have an air filter? Mine just has a metal mesh screen and won't go full throttle unless I am between choke & mid choke? Thanks for taking the time to make the video. It was great! :)
David Chambers You are welcome David
Perfect--Thank you for sharing. This was the fix I needed. Time for some ice cream!
This happens so slowly
Carby clean also works a treat, rather than the propane torch. Cheers
Good idea
I use carb spray and a wire brush, then blow it out with air compressor. Some people burn them clean. Some people take them out and throw the spark arrestor away (don’t tell Smokey the Bear).
Right I like to fix them. It only takes one spark.
Nice one Bruce and you will soon fix that.
Patrick Meehan Thanks Patrick
haha when you showed it bogging at the beginning i said too myself.....spark arrestor. But then you started dumping fuel and what not so I assumed that you knew something else was going on. haha.....its always a good idea to change and clean fuel system as a "while you're in there" job.
matt lemon Yes I always change the fule out you never know what is in it. Bruce
I have a small engine repair shop and get tons of these in . The fix= a 15 mm socket to remove the " spark arrestor " pitch it .The engine runs cooler and lives longer. This is built in obsolescence and boders on criminal . To the tree huggers that say "oh no you can't that " I say go hug your tree and go to bed .
I get it
Nicely done, Good catch
***** Thanks Tugdog
I thought it was the carb, but you were right. It cranks now!
+David Shaper I cleaned the carb first, on this one too.
You don't need any disassembly. Use the screwdriver/wrench tool that Stihl provides and remove the spark arrester directly. Also, a good butane lighter will burn the carbon off nicely.
You are right. I ended up chasing the trouble and was going in the wrong direction.
