Good job, that's a lot of time on bench work does that ever become an issue with the time cost in regards to charging tie customer for that cost , I guess my point is a lot of garages shops will probably just say you need a new one and not even this with it because of the dish work right would be too high for the typical customer to be ok with paying ? Just wondering your thoughts on that
@@johnlsullivan896 I’m not real sure where you’re going with this but A decarbon job is part of a routine tuneup 59.95+ parts
Would chugging after the kill switch be an indication of carbon. Seems like if I run it full throttle before shutdown it doesn’t happen as much Stihl back pack blower 500
@@johnlsullivan896 I have no idea what you said and what it has to do with the process of decarbonizing a 2 stroke
Your videos are solid I subscribe you have given me great ideas and tips and I feel like I am better than a lot but I also feel you can learn from a random question asked by a person that is worried their questions might be Silly!
You can also use a small handheld torch to burn the carbon out. What I did was to bring the piston up to a point where it blocked the hole off and gently used the torch to burn the carbon out. Try not to overheat the area too much. Do a little at a time and let the area cool down before going any further.
Remove spark plug, piston bottom center,10 lbs air pressure into top of cylinder through plug hole, then scrape exh port. No worries of carbon into cylinder that way. I've done this hundreds of times. 30 years at the bench in dealerships. Retired now.
btw - I totally enjoy your vids. chickanic's pretty awesome too :)
another btw - running consistently at less than full throttle will also build carbon in exhaust system.
I was thinking along the same lines. Even tho he was fairly meticulous, he put lots of that carbon from the port into the engine.
@maxsmax5858 yes
You are so right, I never use compressed air
You are so fun to learn from ❣️, what a blessing you are, I know I’m gonna get my whacker back it’s power, I have a Shindaiwa, older model and it bogged down but I just found you and I believe i was divinely led to your videos, so praise God🙌🏼
Gunsmith Brass picks, scrapers and brass brushes work very well and won’t damage the steel.
One of the best videos I’ve seen in a long time. So much great information. Thanks brother
This video came at a perfect time as my Husqvarna 580 leaf blower has recently had performance problems. To me, it sounded like the spark arrestor screen was plugged and when I found it very clean, I was baffled. I pulled the air boot off of the carb and found a lot of oil dripping from the carb, excessive blowback as you had mentioned in the video. This led me to remove the exhaust and I found it partially clogged with carbon. I followed your lead, removed the carbon with a screwdriver, and did the heat soak with Seafoam. Now it runs like new! Thanks Mowermedic1!
Another thing you can do is take Seafoam or Marvel Mystery Oil and a small paint brush and brush Seafoam or Marvel Mystery Oil on the carbon and let it soak for as long as it takes to loosen the carbon. This will also allow you to use a hard plastic or wooden device to remove the carbon instead of a metal device. This helps to reduce scratching the piston. Depending on how thick the carbon buildup is, this may take some time and may require repeated applications of the Seafoam or Marvel Mystery Oil. Using this method, it took almost 8 days to clean an Echo trimmer one time. The Echo trimmer was also three years old and had never been cleaned. You could also turn the port straight up and pour in Seafoam or Marvel Mystery Oil to fill the port full. I haven't tried this yet. Let it soak for a few days and pour it out. Be sure to raise the piston up so that the rings are above the port and use the piston side to seal off the port. This should minimize any carbon from getting down into the crankcase.
Motor Medic you are my de -carbon hero!
I've had my 2 cycle units since around 2008 and they were used when I bought them... I use just stihl oil at 50:1 and I remove the mufflers every few years... never any carbon.
MM1, great video on de-carbonizing. I am sure I can put this procedure to good use. My son and I run a grass cutting business and also run a small engine repair business on the side. Always looking for new maintenance procedures. Thanks for sharing.
Berrrysman's b12 is actually stronger than seafoam and cheaper take 2 red solo cups and pour a little seafoam in one cup and Berryman's in one cup and let it sit for awhile and watch which product eats through the cup first. That machine sure does run better nice job.
B12 is what we use at shop and it’s twice as fast to
Great idea with the seafoam . Happens here on the course all the time . To much idling and half throttle usage I find causes half the problem. Tried doing the sea foam through carb as you said and I think it may have burnt up a few engines ( I’m thinking lack of luberation) ( or they put straight fuel in) I also burn out the mufflers with propane or Benzen when I remove them. Just cause the screens not plugged I’ve found the muffler to be plugged up also to almost tar .
Definitely getting a 👍 from this guy great information. Thanks a bunch.
As you know mm1 we like to use AMSOIL we also trade off our trimers every two years .This system works for us. THE LAWN RANGER LAWN CARE BLADEN NEBRASKA since 1971
A real candidate for Echo Red Armor instead of that cheap crap from Walmart or Running TWC3 marine oil.
Looks like it works fine. I usually just mix it in with my fuel though
PB blaster makes a de-carbon spray for the cylinder.
Spray it in there wait 15 mins then crank it up and it burns it all out. Couple puffs of blue smoke and she's ready to go.
Send a link to pb blaster Decarbon spray please
@@THEMOWERMEDIC1 I guess it's not pb. Just blaster Corp.
It seems everytime I post links that aren't CZcams videos they are removed.
What on Amazon has a diff label though I believe it's the same.

That Seafoam is some good stuff
That sea foam works wonders. Good job. You could do something about your volume, I had you turned all the way up and it was still hard to hear your speech. 👍
I forgot my microphone at the shop sorry
@@THEMOWERMEDIC1 no problem. Don’t do it again. 😂
@@THEMOWERMEDIC1 33:1 oil mix is ok ?
i have a small shop vac with a small tube attachment i like to use for cleaning out the cylinders with
Sounds safer because hard carbon is like sand and rocks
Had a 365 today plugged up exhaust took off and put in woodstove for a hr works great and no fumes in shop
I didn't know seafood would clean carbon that well. Thanks for these videos!!
The Chevy dealer uses sea foam to decarbonize. After a sea foam soak on a warm engine they start it up they drive it to get it out of the shop to avoid the de-carbon smoke. That carbon in a car is emissions/crankcase return to the intake of the engine. That’s why I installed a catch can on day one of my Camaro. I get about 4oz of distilled petroleum out of the catch can every 4000 miles. Otherwise that distillate will gum up the intake.
I’ve had to do that once, but when I did it it was only a very badly clogged spark arrester and semi- clogged exhaust port but not near as bad as your costumers edger 😬 but Awesome job fixing it👌
Acetone: leave it in the cylinder overnight and then drain it softens the carbon.
This reminds me of those earwax removal videos.
I lurnt so much I got Exhausted! Lol
Now that one here is a good one I can do to my husqvarna. It's been a good piece of machinery. Want it to last me 1 more seasons are more It's done paid itself off. Thanks for the tip
I would of liked to see a before and after of Sea Foaming the Piston, worked great on Exhaust Port, you need a small torch on the bench Jeremy.
That Sea Foam ain’t Cheap either.
I warm the engine. Then remove the plug and go to top dead center and fill the head and let it soak. This soaks the piston ring really well.
I've used a small vacuum to suck out debris instead of blowing into the cylinder
Red armor oil and the proper tune will result in in a clean engine. Any oil in a silver bottle is garbage.
Ultra has damaged a lot of cly
I see it often in shop
I wonder if you could get project farm to test that stihl decarbonizer.
Awsome I was just looking at my shindawa t235 and I believe it has that very issue.
WOW GOOD VIDEO Thanks Ed Loretto Ontario Canada
Ah man, I've used seafoam in my riding tractor like that but never thought about using it on my Echo's. I know what I'm doing this weekend. Cheers.
Used to see this on lawn boys
I personally would have left the piston up, hold a vacuum nozzle by the exhaust port and then cleaned it out. Not sure if that would have worked or not
Great job
Or run Red Armor oil in your mix. Their detergents are incredible.
In a high pitched keyboard cowboy voice: “ But MowerMedic your going to blow it up!” It makes me laugh when I hear and read some of the ridiculous and uneducated comments that you get. You are definitely a better man than me. Forrest Gump was right when he said “stupid is as stupid does”.
that sea foam's great stuff !!!
Run Echoe's Red Armor and have never seen any carbon.
Wow those echoes are pretty good considering
Exactly what I was looking for. My stihl is doing this and didn’t know what to do. 2 thumbs up
Would you also check the spark arrestor too? That hot soak is what I use on my mower. Works very well.
pressurize the plug port while you scrape
@THEMOWERMEDIC1 The main mechanic at the place I work at said oh as long as ur careful you can scrape the carbon out. Uh no I like your idea about soaking, blowing with it upside down better.
Oh no! That poor ozone layer!😅
Decoke the exhaust as well.
I just learned something! Thanks!
On heavily carboned engines there is a possibility that the carbon removal in this proceedure can stuck the rings…it’s a known proceedure in older 2/stroke outboard engines …but usually not recommended if this decarboning wasn’t done on a regular maintenance schedule…
You are fun to watch
Or you can just use red armor 2-stroke oil, it actually does d carbon a two stroke within two tanks. Steve's Small engine saloon actually tested this, I was shocked. It made a spark arrestor screen in a blower go from 95% plugged up to looking brand new!
Awesome 👏
What about just switching to Echo red armor 2 cycle mix and using it normally. Would it clean itself over time?
Probably not
It's supposed too, I watched a video where one tank of red Armor 2 stroke mix cleaned some carbon off the top of a piston on a chainsaw. Just 1 tank did it so I can imagine using it daily you'd never have carbon build up since its suppose to remove carbon anyway.
I enjoyed the Smoke Show dude! 😂
Seafoam is ok but rxp is a de-carbonizer thats what you want
Sea foam on the brain !lol! Brain farts suck!thanks for that lesson I have an echo srm that's really bad ,it will be fixed now for sure
Great video Jeremy. That is the worst carbon build up I have ever seen. The 2nd link to the sea foam pour in is not right it takes you to the amazon home page.
Hello, great video sir.. is it ok to use fine sandpaper to clean the carbon off the top of a 2 stroke piston and also the inside of the cylinder head?
Hey mower medic, do you reckon running too rich a 2stroke mixture causes that kind of carbon build up, or is caused by using cheap inferior brands of 2 cycle engine oil?
Wooww awesome he answered your question. Must be super busy to take 2 minutes at the most to answer you. I guess these CZcamsrs don't realize we're why they have channels.
Another major reason for the carbon build up is running the engine at low speed and low load, the engine doesn't get hot enough to burn the fuel and oil effectively and they pile up at the exhaust port, muffler and spark arrestor as carbon
Red Armor 2 cycle oil. Just bought a six pack and try it for a season on all my equipment. I’m using ethanol free boat gas as well.
Yeah running to much oil causes this and like the other commenter posted just feathering the trigger and never running the engine at higher speed causes it as well because it's not getting hot enough for burn off. I now mix 40:1 on my equipment made 25+ yrs ago and 45:1 on all my 2 stroke equipment thats newer and calls for 50:1. The old mentality of more is better does not work because of how much better these new oils are but I still err on the side of caution. Another thing I do not do is buy cheaper branded oils Husqvarna xp or echo red armor both are affordable good oils. No matter what you run or how you run it there will be carbon build up eventually over time I'm not a big sea foam fanatic but injecting a LITTLE maybe twice during the season like he did here will help prevent a large build up. I have also mixed small amounts of mystery oil with my gas aswell. Nothing compares to actual maintenance of equipment but these additives in moderation still have a place for these small engines.
Thanks
There is an easier way of removing carbon. Pull exhaust out piston all the way to tdc use screw drive scrape out. Brake clean the port when done. Or use carbide burr bit. If u want to really be extra add marvel mystery oil to it when done. It works on the 4 mixxes really well. Let it sit for a few hours with the cylinder full and each valve open one at a time....
😂😂😂
Question: my Stihl 032 is very hard to pull, to a point I cannot crank it! I can remove the spark plug and it is very easy to pull. Everything looks great, the piston, the exhaust port looks great. I have cleaned the air filter and the spark arrestor which wasn't clogged. It ran great the last time I used it, any idea what could be the issue?
Can’t compress a liquid. Replace the fuel delivery system
@@THEMOWERMEDIC1 So, you think there is too much gas entering the cylinder?
This problem was very common in the old days. With modern JASO FD oils this will not happen.
yup cheap shit oil does this.
Great info . Well coked up .
I’m sorry but I can’t hear well and would like volume turned up
V16 for 57 years has done it’s due
Very nice video ty !!
It’s not just 2cly it’s 4 cly also
Don’t use the cheap gas with corn crap in it, it just turns to carbon on piston
yes 4 new oli keep weed a year 4 my have that long the oli mex look clean to that way
Is seafoam like brake oil
Do you have a video on removing carbon from a chainsaw? That was an awesome video and had no idea sea foam could remove carbon so good. Thanks for sharing cause this is the first video I've seen of removing carbon from a 2stroje
Sure do
stihl numer 1
Very nice
What caused this severe carbon buildup? Was someone running way to much oil? I run my equipment at 40 to 1 and I’ve never seen anything like this. When I replace a top end on one of my 2 stroke tools the ports are clean. I can’t imagine how rich an oil ratio you would have to run to cause this much carbon.
not running at wot for extended periods will cause this... seems to be a common cause on string trimmers... red armor cleans carbon build up it has additives and conditioners added... straight oils lube just fine but can contribute to problems like this
Yes, i agree it's short journeys at low revs, i knew lads with vespa scooters with this issue, using standard vespa autolube. my 2 stroke bikes never suffered, as they got a good revving.
I see in this video that you ran the engine briefly with no muffler in place. I tried this on my Poulan Pro BVM210VS . As I pulled the starter recoil it seemed like it was running for a couple of seconds each time I pulled the recoil. Can it be that the muffer is so packed with carbon the engine will not start? The spark arrestor looks clear but cannot be removed since the muffler is sealed. The exhaust port was not that bad as far as carbon . I did try to remove as much as I could. Compression is 105 PSI. Spark is good. I have tried two different carbs. ZAMA C1U-W45 Fuel lines new, fuel filter new and primer bulb replaced. I see on other videos to check the head bolts. Good and tight Any idea of why this leaf blower won't start?
You need better ventilation in your shop .😮
@THEMOWERMEDIC1 _Need some help please!_ . Is this something I can do with my 4-Strole/Cycle rideon mower? I have done all the standard maintenance (new airfilter, plug, oil) cleaned the carby and checked/replaced parts and seals. I am getting blowback from the carby but I haven’t checked the muffler or the exhaust port. Motor is an old *Honda GV400K1* vertical shaft. It’s electric start and I did get an hour or two of mowing done after I serviced it but now she won’t start…it has compression and turns over fine but just doesn’t get over the hump/start? I’m in Australia 🇦🇺
Good video
Will that work for a craftsman 25cc weedeater the sea foam
Absolutely I will
Two year old BG 56c with cylinder lock. Disassembled thinking carbon locked and connecting rod bent. Cylinder and piston very clean. Any thoughts?
Thank you for posting. What phone app are you using?

very helpful video sir, i have a vintage 2 stroke bike and i just discovered that my exhaust pipe is clogged. what would you recommend to clean it out without using drastic measures such as heat, i saw that you used sea foam and it seems to do the job. but for longterm soaking what's your best advice. thanks for the videos and have a good day.
Run Yamaha Ring Free additive in your gas and you should never have to de-carb the engine again. I don't know how well it'll clean one that's already carboned up, but it will help.
EPA going to give you a visit .lol
Hahahaha. Bring em!
@@THEMOWERMEDIC1 you heard what they done to diesel brothers 900 hundred thousand dollar fine
@@stephanied143 That’s because the diesel brothers word programming and deleting emissions control equipment from trucks I am not doing that
They can get in line behind IRS and game wardens
Thats a lotta carbon
What causes the carbon buildup? Carb not adjusted or heavy oil mixture?
If yoy haven't serviced your 2 stroke offen enough , its time to strip it down and rebuild it .
Pissing around scratching a piston is a sign of a non qualified person.
Need to upgrade the mic or move it to a different location. Voice is real low and engine sounds are real high.
It’s your speakers. Sounds great on my end

Check out my post in my community tab
Can i add some mr muscle oven cleaner ? sea foam is not available where im from
Not disassembling the cylinder guarantees this loose carbon getting sucked into the crankcase through transfer ports and getting into your upper and lower rod bearings as well as possibly scuffing your cylinder and piston. Not good! Take his advice at end of video and remove the cylinder and do it correctly. I tape inside of cylinder at exhaust port and use seafoam. Soak top of piston with seafoam ensuring ring/s and grooves are carbon free. Use good synthetic or synthetic blend oil. Husqvarna makes a great 2-stroke oil for these type of engines. Heat, a crappy oil, and set way too rich make carbon accumulate much quicker.
She could use a port and polish...
That’s funny you say that, but did you know a highly polished surface will not attract carbon buildup
@@THEMOWERMEDIC1 well I don't go as far back as whale oil and two strokes but I remember when I started we had to grind our own Castor beans for the oil LOL
Improve your volume next time. Wear a mic That'll help. Ugh
I think I have a carbon problem in my ms 251. It has gotten so hard to pull over it has whipped my butt. I have a bottle of Stihl Decarbonizing liquid. I am going to warm it up, today, bring the piston close to TDC and fill it up with the Stihl product. I will let it sit for eight hours and then pour it out and run Seafoam through it while it is running, assuming I can get it going. Does this seam like a good plan? I have never had a 45 cc saw whip my butt like this sucker has.
How did you go?
Australia
@@glennllewellyn7369 it still whips my butt.
@@glennllewellyn7369 it still kicked my butt but the problem was I had switched to a JASO oil instead of Stihl Ultra at 50:1, and the extra oil it leaves in the cylinder jumped compression out of sight. When I switched back to Ultra I could crank it, not easy, but I could get it running. Stihl should put a deco valve on the 251 and MS 250. Husqvarna puts one on the 445 and so should Stihl. JASO FD oils are good for the engine but are hell on your arm and shoulder.
@@johnclarke6647
Ahhh interesting. Maybe running a little rich to have that extra oil floating around? I dunno, I'll just go back to being a shitty beef farmer cutting Red gums up with a borrowed 661...
Raced many two-smokes for many years and still have buckets of ester race oils in the shed. These oils get devoured by my saws etc. Never a problem if jetted and tuned properly. 45:1 for summer in dusty conditions and 55:1 for cold winter and rainy wet conditions. Basically I always mix 55:1then add a dollop for shit conditions. Keep the air filter clean as a dirty one sucks more fuel. Every few seasons a dribble of white spirits or similar around the cylinder to keep the rings from sticking(tends to work on the wife too)
Have a super day mate. It'd be nice to get over there one day!
Glenn
@@glennllewellyn7369 no, FD oil stays in the cylinder and crankcase more so than other two stroke oils - part of the JASO FD specification. The problem is more oil in the cylinder increases compression and a saw that was hard to pull over becomes almost impossible. I run either Stihl Ultra 50:1 with premium non ethanol gas plus a stabilizer or Stihl Moto Mix and I run these in everything I own, two cycle - about 25 pieces of equipment from saws to hedge trimmers, weed eaters, blowers, etc. I even run it in my MAC PM 610 and Homelite XL -12 and Poulan S25DA. I do not discriminate and ain’t going to have two different blends of gas lying around the shop.
Hey mower medic, I have what looks like carbon built up on the piston. Is my piston shot for sure now?
