i remember a couple of years ago i stumbled across your channel
you inspired me to get into small engines
this week i got hired at my local small engine shop
thank you mustie
Good luck. Learn that things can be fixed, but disposable engines are always a possibility.
Good for you!!
Congrats to you. Ive also learned a lot from Mustie and from other similar channels.
Awesome man! Done Good !
Congratulations! Enjoy!
My favourite time of Sunday evening, in bed, hot cup of tea and a Mustie1 video. Good evening all from Adelaide, Australia.
Nice HQ, mate! 😉
@hqwoody327 Thank you! It’s just a 202 auto Kinga but it’s not bad.
I had a wine tasting in Adelaide with a nice good looking tall woman who is very forceful but her husband was always in the pub
same, except morning and a freshly brewed hi-caf tea
I liked Adelaide, visited in late summer in 19
Loved every minute of it, 100x better than anything on TV!!
Thanks Mustie for inviting all of us into your little operating theatre. First time I've seen you do "major surgery" on a riding mower engine like this. Even though it eventually turned out to be just an "autopsy" it was still very interesting to see what "killed" this fine specimen.
Geez one bolt fails and the crap hit the fan! Thanks for having me over to hang out in the garage bud it's a good time as always.
considering the diameter of that bolt, relative to the hole, I wonder if the design got undermined by "yeah, but if we downside the bolt, it's a few cents cheaper per 1000", and then it snowballs *hard*
@@tamberp The 40 cent bolt...IS NOW 30 CENTS! LETS GOOO. **sad 20 year old engine noises**
This is just stupid. It's a counterweight: why not just use a really big grade nothing bolt instead? Reduced thread, machined nut, I can only imagine what this cost. But FYI airliner engines are held on with two bolts, so if one of those fail then figurative crap really hits the literal fan!
@@paulmoir4452 CFM and v2500 engines have five mount bolts up front and four in the rear. They are all over an inch in diameter. I struggle with a four foot torque wrench to torque them.
I can hear Project Farm going: Wow, thats a lot of damage!😁
Yup. This engine went to the great scrap yard in the sky.
That damage is "very impressive!"
I wonder what he "Project Farm" was testing?! LoL 😂😆
I think Musti should put it back together with out the balancers, see how long it will run wide open til it seizes
Hahahahahahahahahaha lol
No matter how old we get we're all still a little boys that like to take things apart to see how they work
But can we put it back together again ,is the question 🧔
See, I think after we learn how things work, we begin to regress in a way. We start taking it apart to see how it broke! After we get our giggles out, then we start to fix it.
Too often we see how others failed at solving a problem and yes....made things worse. The Mustie types come along to fix the screw ups and then go after the original problem. Happens in my world every day.
@@gispel7058 Hard trying to solve a problem with somebody else having their fingers in it. had a chevy cruze (ew) 1.4T car, misfire all over, everything looked ok ish. After we were doing some testing ect, had it running, full on oil, Turbo started just making awful noises. Long story short, they did horrible oil changes, clogged the turbo oil feed, the son put a used turbo on it, not changing the line, breaking the drain line, and then came to us for a missfire. So DIY gone wrong, aswell as poor maintenance.
@@baileyhatfield4273 Its a problem alright. I don't work on cars and engines but I do mechanical work. Glad you were able to look at your problem and back track what the heck went wrong.
Banging on that crankshaft in double time was downright musical
Good video. I finally found me a hammer like you have. At the flea market last weekend for $1.00. Been using it last week. Thanks for the videos.
Same found mine at a yard sale 2.00
I'm sitting here on a sunday morning and watching LSI (lawnmower scene investgations) and I couldn't ask for anything better. The way you look and diagnose what went wrong with that Toro was nothing short of amazing. And I always enjoy watching a master at work. Love your stuff and keep up the good work.
" LSI (lawnmower scene investgations)" Now that's a good one !!🤣🤣🤣🤣
Ditto on LSI. LMAO and no one got killed!
Threw the counter balance, Kohler courage for ya. I work in a mower repair shop and it happens all the time
Hey, I want to thank you for all the helpful videos. I retired and moved to Northwest Arkansas in the deep Ozarks. It's pretty much just my wife and me. Since I found your channel I have been able to work on my own small engine equipment. I can even help neighbors. It's been very rewarding. Thank you.
I really like the wrap up synopsis- really helpful for you to run back through what we’ve seen as the final “act” of the video. Thank you.
Your trick to spin the allen wrench blew my mind.
I saw that also!
I saw that and was gonna comment how good he is with a left hand to boot.
My neighbor gave me a honda push mower that was locked up. I soaked the cylinder with pb blaster and have been using it for 4 years. Love the videos musty. You have really increased the depths I'm willing to go before I give up on equipment. Thanks 😊
Your videos are never long winded...always very informed and n depth...no one else would go into detail like you..ty very much for what you do and how you do it...never change your style or videos..
Just wanted to say thanks for all the information on small engines. Just helped my friend with a Kawasaki 15 HP twin with a bent push rod. Straightened it out, put it back, adjusted the valves and it LIVES...lol...never would have tried that without watching you. Keep em coming to Walkertown NC.
Thanks for your educational videos. Recently bought a 20€ lawnmower and within 30 minutes cleaned the fuel system and carburetor and now runs like a Briggs & Stratton 😀
What a weird engine! Never seen a fixed counter balance like that? Thanks for getting your hands oily and showing us!
I'm going to guess it has something to do with the unbalanced (otherwise) magnet on the flywheel. Overly complicated POS if you ask me. Not only that, but there's cut corners everywhere you look. Thin case, no hardened surfaces against gravity effects (the part that Mustie was showing that got munched in the crank case), there's clearly no oil ramp, and this relies on other means to get lubricated...
If i were to bet, i'd bet this engine started life as a vertical engine, then some smartass in the cost cutting department decided to swap it to horizontal, with the required modifications, to which there's no issue, it can be done, but if you do it whilst nursing your thumb with your .... it won't last. And a cursory glance on google for this engine proves my point. This engine platform is riddled with problems, from cracking to spun bearings and other stuff. What a piece of junk.
@@aserta buddy...this is a vertical lol. The counterbalance is meant to oppose the vibrations created by a single cylinder’s piston oscillating up and down. Now most single cylinders just use a balance shaft including newer Kohler. The piece that was chewed inside was likely an oil baffle to avoid the foaming of the oil around the governor gear.
@@aserta "What a piece of junk" I will second that motion.
John
@@aserta flywheels are also balanced. You’ll find drilled holes along the perimeter to balance and reduce vibrations.
@@joshuaolsen8844 Oh jeez, and a bushing for the counterweight is completely inappropriate for the side loading that occurs in that orientation. It will always be pinching on the bottom/piston edge and top/counterweight sides because of gravity pulling it downward.
Your presentations are amazing Mustie ! The humour stands your channel well apart from others out there and we can relate to your findings as though in person. In truth i think we all watch for your trademark phrases lol.. "think it's got spark..." "think it'll run" ... "well that ain't good" ... and then .. there is the laugh! You Sir.. are an entertainer and a joy to watch with your tear down and repairs. Here's to the next video and thank you so much for sharing
Great autopsy on that engine. The synopsis you did to explain the failure was amazing. Thanks for posting this video :)
Good show, Moe. The sinister laugh at the end when putting the crank back in with "Up Next. Will it run?" is cliffhanger material all day long. Hysterical and surely has us wondering how bad it will be and how long it will last!
I have the popcorn ready for the microwave and time on my hands bring it on destruction here we come. Will he do it oh yes he ran the twin cylinder with one piston and jug let’s start the pool for how log it lasts.
Edit: I give the engine 2 minutes 29 seconds before it locks up.
You are a power house, tearing into this thing at turbo speed. Love the energy!
its inspiring, I have been getting faster working on my projects now
LIkely from years of working flat rate, in a prior life.
I absolutely love all your videos Mustie. I have learned so much about the functionality of anything mechanical to tool use. My hobby is restoring mowers, weed eaters, and pretty much anything mechanical much like you. I was wondering how/where to send you a thank you package. I’ve had some hard life challenges and your videos have gotten me through them. Please PM me to where I can mail you some thank you items. You’ve inspired me to track down the moped I used to have and start restoring it. Thanks again Mustie you ROCK!
Man, I really got a lot out of this video. Thank you so much. I really appreciate the time spent on you explanations of the overall mechanics.
I never tire of riding mowers.
same or garden tractors and idk why, just good cheap fun to try and get them running.
🤷♂️😏
@@garymallard4699 nice! I got a few at the moment, from 60s-90s, but simplicitys and a snapper LT12, either got em all for free or under $85. Like you said, fun to just revive them, trying to figure out this valve tick on a briggs cast 10hp, need to replace the valves and then might need rings. Fun to learn on. Those Ropers are great tractors from what I've seen
@@garymallard4699 nice! That sounds kinda like the attachments I'd like to have, but realistically don't use as much as I wish. The loader would be super handy though and zero turns are quite a bit faster, I guess overall a few mph to 10mph faster and turning. And yeah most cases with things I get free in the garbage is bad fuel/car or safety switch/no spark. Most my garden tractors were rode wet and put away hard though lol
Love the what ifs teardowns. Learned alot about the interaction of components. Thanks for the look.
Well I was looking for boat hull restore info and I find this vid that has nothing to do with boats. Well I have lawn stuff for parts or repair.
So i find myself riveted to this video and here is why. I hate videos that sensationalize, monologue to much or can't hold the camera still
or drown out the sound with some crazy too loud background music. Also hate that lots of vids have no point or just don't know anything
but brag about themselves..
So this guy does an informative video that completely makes true sense of things right before your eyes and ears. So well informed, so thorough, so comfortable and easy to watch. Answers so many questions and makes you feel like your at your friends shop helping him figure out what happened. So now I am informed, learned plenty and gave mustie1 a thumbs up and subscribed. Mustie 1 should be teaching tech schools. He doesn't brag so I thought I would do that for him as in reality it should be. Give credit where it's due and dont brag. Put it in your resume'. Thank you Mustie 1.
thank you sir
Classic Mustie ..... "its comin out, it just doesn't know it yet" ! Oh how I love this channel !
Q
@@sergeblanchette4201!!!!!!!!!!!!!!
Low oil or oil pump and just because it's full of oil people have tendsey to ad oil after it has burnt lower balancer out
Or never change oil
Greetings from Thailand. Thanks for the small engine (including VW) education over the last couple of years.
Such an inspirational & educational channel, & yet a minority still give a thumbs down.
Those people need to go back to bed, have coffee or sit in a bowl of rice or something!!
Those are hopeless dingbats. They refuse to learn anything worth. I have no pity for that kind of people.
You can pretty much guarantee that they are the sort of useless people that have nothing to offer so just want to whine about something. None of them will have spent any time making videos to try to help or entertain others and they cannot understand the distinction between not liking something and disliking something. Not one of them will have left a comment explaining why they did not like the video so it says more about them than it does the video.
Those are the people that think lawn mowers are Porsche’s and Mercedes and over think what needs to be done yea he is off the cuff mechanic but he knows how to make things work when they do not . Taryl said it best “it is not the space shuttle it cuts lawns”
Those thumbers downers are probably people hoping for a fix on their own and it didn't help them. So much negativity around but mustie1 just blasts it away as always.
Good job, I'm hooked....I've been taking apart and most of the time putting together all my life.....I still push myself to do all of my own work [I just turned 72]........but the satisfaction of [gettin it fixed] is a great feeling...........I can hear your amusement when you [hear it run].........you've got a great personality thanks a lot for the intertainment.
MAN! This has got to be my absolute favorite channel! Your depth of knowledge is astonishing! Mesmerizing actually! You should teach this stuff! I mean beyond what you do for us here! You didn’t have to go that in depth, but you did! And I’m profoundly grateful for that! And to think, we’ve got someone of your caliber right here in the Granite State! Thank you once again!!! I’m a Mustie junky!! Hey, that’d be a wicked cool t-shirt!! Mustie1Junkie Club!🤣👊🏻
Yay. Sunday evening with Mustie to watch. Hi from New Zealand.
Good morning Mr Mustie ... Good to see you today.
Very good Mustie, I've never seen the inside of these newer engines. All of my experience is with the old iron Briggs and Kohlers. Thanks a bunch.
Art
I have owned a mower with this engine for the past 8 years and have had no issues due to regular maintenance. One day while going over the mower I noticed all the top cover bolts have come slightly loose most notably the ones near the back where the locating thing that that screw screws into and is located in the top case. I think what you said about the bolt failing and working loose is true, but I think the reason said bolt was able to work loose was because of warpage or looseness of the top cover where that silver locating thing sits in the case. Fingers crossed mine keeps going haha.
42:42 Southern Auto Auction note pad on the work bench! I was a wholesale buyer for 26 years, met my wife there in '92 she was a title clerk. I attended SAA up until 2017 just about every Wednesday.
I love the projects that you get into. The way you explain things is great. Thank you for sharing b
This is the real, reality t.v. Very much enjoyed watching and appreciate the posting. Especially the information you gave during.
You’ve got to love wrenching vicariously through Mustie, and maintain clean oil free hands, thank you for allowing us to be there with you whilst you do autopsies on stuff 👍
Always a pleasure and an education Mustie!
I'm a dedicated viewer as I learn SOOOO much watching your various challenges, diagnoses, and solutions. Apart from your mechanical understanding of engines (of all types), you include a strong understanding of the physics at play in engines. I'm curious, are you self taught? Hoping you might give us some insight into how you garnered such a deep knowledge of these things. Also, you uniquely speak to us as though we're there in your shop, further immersing your viewers in the process. No wonder you have a half million followers. THANKS!
Don't know what his back round knowledge is? But what ever it is, he's like a regular kind of guy.
Mustie is like that neighborhood dad, always willing to lend a hand to anyone willing to learn. Show your interest and he'll teach you anything you want to try.
I don't think he learned it from his dad. In a video of his parents his dad didn't seem very knowledgeable about engines.
Love each episode of Musti 1 ever since i met him and the karman giaha a couple of years ago. Learned lots from your videos sir. Thank you very much.
Makes me glad my Toro has a B&S motor. Only issue I've had is with the decompressor. If the valve clearances are a bit too big the decompressor doesn't work and the starter struggles to turn the engine over. I bet many people have replaced batteries or starters only to find that all it needs is the valves adjusting.
Mustie's enthusiasm is admirable. I'd be like "Crap, guess I gotta take this darn thing apart..." Mustie is "Cool! I get to take this apart and find out what's wrong!" 😁
Once I found the huge gear thing and the destroyed spring looking thing, I'd have stopped investigating.
@@garymallard4699 Nope. Accurately diagnosing the problem, like he did, is the real talent. Then a reasonable assessment of whether it's worthwhile to repair, considering costs vs returns must be made. He didn't just "tear it apart", he methodically followed the evidence to find the root of the problem. If you don't like how he does his videos, make your own.
@@garymallard4699 who cares? Mustie did a great video, guiding us through the discover process of finding the problem. You come along with some punk comment about all he did was tear it down, which is easy. You missed the point of the video and took the opportunity to brag for no reason at all. Go away.
There is a huge emotional difference between "Lets take apart this mower to see what happened." and "My mower died now I have to fix it before I can get back to mowing." The first is a fun exploration the second is compounding work and can quickly get exhausting.
There are trolls commenting on almost every video I watch, like the comment of having a happy wife, that guy is watching the wrong videos.
this channel is relaxing versus the chaos of hearing todays news :-O
What happened?
What are you talking about?
Ain't that the truth, the news is always some sort of calamity
ohio yoder toter ... Oh yes! Today's TV and print "news" is so messed up with "reporting their self-righteous opinions" instead, its not worth our consideration.
As long as its not another attack on the whitehouse by a bunch of well below average IQ traitors, it will be good, happy mowing.
Thanks for explaining how the oil flows through the crankshaft. Learned something new today.
Always learn something from you Mustie. Thanks again.
I appreciate the discussion as much as the wrenching. Definitely helps me learn.
I, personally, like how He talks to us, just as if we were actually there with Him! He's a naturally born teacher! He is patient and takes the time to delve into something, with an inqusitive nature, and is always figuring on repair and riding it around the property a while, to check it out and give us a thrill ride!
I've been waiting since 5:30 AM for this.
Good video, start to finish. I've learned avoid YT videos with AMAZING, GENIUS, and YOU WON"T BELIEVE titles. I'm glad I made an exception on this one.
Thankyou ,I have always been curious how they worked but never had a patient teacher. I love your csi style.
What surprises me is the engineers would have to have known that bolt was completely wrong for the counter-weights. Yet, here we are. A more unusual reason for engine death we've seen on your channel. Much enjoyment derived. Thanks, Mustie1!
I think it's much worse than just the bolt. Think of the bearing side loads from the counterweight being pulled down by gravity. This sucker was never intended to be run horizontally.
@@photodan24 Very good point!
Kohler really made a turd when they came out with that engine! The Courage twin was pretty good, but I shortblocked a ton of the singles under warranty because the cam boss in the bottom would crack and lose all the oil while running and BAM! thrown rod! Compression release was problematic too. 99% JUNK!
I agree on junk
That Kohler Command took a licking, but didn't keep ticking! Great video, as always...extremely knowledgeable!
It's not a command. If it was, it wouldn't have failed.
Thank You for all the super Videos Mr. Mustie sir. Your as good as I like Lucy show.Please keep making great videos sir.CHEERS
It's amazing how the simplest little prick can cause such a BIG problem! The way that governor exploded was CRAZY!
Should see how the old Governor of Cali's head exploded in Total Recall
@Demonfang Arun nah the bolts just break. It's extremely common. His analysis was probably pretty close to the series of events.
Dude!! Spoilers!
@@TheAncientOneYT now that's funny right there.
@Demonfang Arun s
I was beginning to think there might not be a video this morning...whew.
He uploaded this at 7:00 AM his time
Kohler 🤦 used to be a tough motor, only behind Onan & Wisconsin. Now handily surpassed by Predator. Sad times we're in.
Another great adventure Darren 🍻 I think your diagnosis is spot-on. I know those things like to eat those plastic cam gears too.
Excellent analysis Mr. Sherlock ! I learned a lot again. Thanks !
it's amazing how he could pull things apart & remember how they go back together i see mustie as a teacher in a trade school he's that amazing as a matter of fact i watch his vids over n over again he's so amazing
Good morning all, coffee and Mustie1 on a Sunday. Happy Mother's Day to all you "mothers" out there. ;-)
Thanks Mustie - another great episode !! 👍. I appreciate you doing these vids - always learn something and have a good laugh as well. Cheers !
Thanks Mustie1,
Good to hang out with you for a while.
Central California Watching
...... a couple more 'who's your daddies'......Gotta love Mustie's commentary .
As Taryl said, they call it a Kohler Courage because you need courage to work on one! A Command would have never behaved this way!
I always learn something new from watching your videos. The weed eater video saved me some cash. Thanks for sharing and teaching.
Mustie your explanations and mechanical skills are inspiring Keep em coming
i have that engine on my Craftsman LT2000 nice to see how in works on the inside Great job enjoy all your videos
Always a fun synopsis. The force of gravity allowed the lower side to drop and get out of alignment every time the motor was stopped and restarted. The upper would remain flush on the bearing surface. Look forward to the rebuild/re-power.
Hi Mustie, I really enjoy your stuff so thought I would send you this one. 20hp Courage single would lock up at TDC. I thought it was either Battery or starter motor. Replaced both with new. still no go. THEN while fixing the leaky rocker cover gasket I decided to check the valve lash, 17 thou on the exhaust which of course rendered the automatic decompression in operative which made full compression too much for the starter motor. Reset valve lash to 7 thou and all is well.
I haven't seen this on your site or any other but I am sure I am not the only one with this prob.
Keep them coming bro. I am learning lots.
Have been watching the channel for a time. Love to watch you and listen as you work. I have added to my bag of tricks as you might say. My first time to comment. Thanks for the video.
Coffee and snack time + a Mustie1 video = a great Sunday : Happy Sunday all
IKR, if only he would do a daily video....now that would be cool!
@@davidfoulk3078 ... yeah, every day at that certain time, CZcams's circuits nearly overload from the strain!! Wonder why ...?
Jeez I was just singing the praises of the old 70s/early 80s Kohlers on Diesel Creek the other day. This is what they have become, nylon gears.
Very good diagnosis. And you are a very good teacher. Thanks.
Your instructions are spot on, thank you for the great tips and confidence to attempt repairs.
It's mouse revenge! One got pissed and got in there with a small jack hammer and had at it! : )
What a weird internal set up on that engine. You'd think standard counter weights would be fine but there you go, a whole motor wrecked after that one bolt snapped. If that bolt hadn't broken the next wear item would be that locator cam/slider thing. This is why Briggs & Stratton engines are as simple as they are.
We have a twin of this Toro. Fingers crossed we don't experience this failure. I had to "re-engineer" the deck and pullies in an attempt to get it to quit eat belts.
Nice detailed teardown.
I really enjoyed the engine autopsy. This is one of my favorite videos of yours.
You're like me, I still have T-shirts from concerts 25 years ago. I mention it because I saw yours was 14 years old. Mine have weld spatter holes and stains and caulk and epoxy but I still consider them valid work shirts!
Good morning Mustie1 and alll the Mustielits from Maryland, USA.
Another Marylander sort of happy for the rainy Sunday morning. I can watch Mustie1 with no guilt about not being outside cutting my lawn. :)
At another Marylander
Back in high school, I made several old Briggs run with many parts missing - the preview did not disappoint me. Can't wait for next vid.
Thank you for this video, it will be a great help in a Kohler that displayed symptoms like this motor did.
I have an Ariens mower with the same engine and the counter balance came apart. It was at idle and came through the side of the block. I replaced it with a Predator 708
Every engine manufacturer has gone down in quality. They are just not built to last anymore.
@@1988MowerMan I was trying to repair oil leaks on my tecumseh 12hp on my riding mower. I pull the repair manual by the id code. Its a "long life" engine. it was made over 30 years ago and still runs. I was amazed to find I could get the entire gasket and o-ring kit for it. Oil leaks fixed, still cutting grass.
This guy is awesome
@@orbitalair2103 Nice : )
"Magnetic Mush" was a lesser known heavy metal band. From the eighties!
I want to say that in my fakest Russian accent like your referring to Bullwinkle.
You really help me understand how the motors work
Mustie, love the diagnostic work you do!
I love this channel. Mustie HQ would be like Disneyland to me. The perfect life!🙂 I love wrenching on stuff.
It was amusing watching you stand there and repeatedly try to turn the engine over by hand trying to figure out what was the matter. Reminded me of someone who gets an unexpected letter in the mail and spends 10 minutes trying to figure out who sent it or what they want instead of just opening it.
I am constantly learning from your forensic failure ,,thanks
Pretty interesting...always learn something from your videos! Thanks for the "teardown" to see what probably led to the failure.
When it was low on oil, the oil was in the moving parts, and there was no oil for the pump to pick up. After it locked up, the oil drained back down, so it looks like it had oil in the case. I've run Kohlers for decades, and never had one problem. BUT, I always check my oil before using, and NEVER run it if oil level is low. Even my 1995 Kohler Magnum 18hp opposed twin still is solid as a rock. All the damage is from "Lack of Oil". I'm 77, and have never had one engine go bad. I've raced bikes, boats, cars with no engine problems.
Awww my favorite day of the week my sunday mornings with Mustie 👍👍👍👍
Good show, Mustie i love learning about new things
I have a feeling that the pin holding the counter weight was tested during the design phase in CAD and tested to pass the forces but not fatigue. It does look to be on the small side.
Mustie’s small engine true crime is a great watch.
At 2:06 my guess is the low oil safety switch shut it down. Lets continue the show to see if im right.
Edit: well i missed that by a mile. Maybe next time.
Maybe ! I still say governor drive gear .
Yea that govonor gear was mangled pretty bad I am surprise from manufacturing they did not just weld those weights together I am also assuming the bolt was loose to begin with and not tight I or not meant to be tight . Here is another interesting thing with the weights mounted sideways how are they going to balance a sideway’s force the weight would be working against the bottom of the crank if you know what I mean .
These do not have a low oil safety switch. At least the ones I have dealt with.
Nice explanation. One of your best videos..
Love the videos I have learned so much. Thanks!
