Piston was like "whew, that was a close one!"
No shit !!!!!!
The little incidental sounds make these videos even funnier.
Never fails to make me smile. Thank you Sir!
That little bolt always dreamed of becoming a valve, but he didn't make it because he got caught screwing around on the job.
Good one!!!
Now all of us would love to see you actually start preparing that engine now that you found the issue... And if you could make a video on getting this engine repair we would love it
All of y'all eh? You got many mice in your pocket?
@@TarylFixesAll I'd watch it, I love your 'How To' vids!
@@TarylFixesAll No mice in my pockets but, I sure can recognize a rat, that pretends to run a country.
@TarylFixesAll I'd watch those too. Your how to videos are what I consider to be elite in the realm of how to videos. Your how to upgrades for old Breaks and Scrappums hold a special place in my heart. Never stop never stoppin.
Fluffy put it there. He got tired of of all the noise and destruction of his home. He's quite the engineer. 🐀
Yup it was that Gremlin Fluffy
@@georgemartinezjrI've had my own problems with that same Kohler. Self tapping screws used throughout. A pile,IMHO . IT is used on many larger 0 turns.We had them on our golf course here.😢
Should have known fluffy's uncle is murphy.
I've had the same thing happen. I welded it back on the other piece. Didn't fall off after that. I had worked on mowers since 1971, I've seen it twice.
I have seen the screw from the throttle plate get stuck in the valve in Briggs&Stratton Quantum once. There was no damage, I even reused it to hold the throttle plate back on.
Please keep bringing on the great videos!
Thanks guys!! I have one of those motors in my JD317. Ironically it came to me with a 2 inch bolt behind the flywheel and it was grounding the stater coils to the block. "Mystery" solved. That's how I got a 317 for 300 bucks with snow plow and tiller and mower deck. By the way, I whined on here a while back about that motor backfiring. Turned out it had "long thread" plugs in it. Put short thread plugs in and it runs great now. You guys are the best... "Old guy out!!"
I've a roughly similar failure.
Honda and clone engines use a metal wing nut to hold down the air filter, and a plastic wing nut to hold down the filter cover. The problem engine had only the plastic nut holding down both the filter and cover. That's not unusual, it's one of those "extra" parts, so it barely was worth noting.
It had failed by locking up, preventing it from being pull started. But it would sometimes free itself after being moved. It may have also had a broken pull cord, as that's. a common follow-on problem. ("Just needs a new pull cord" is right up there with "ran when parked" and "just needs a new battery".)
After checking that that the valves weren't jammed, I dove right in by opening the case. I expected to find something something jamming the crank, splash fin, or gears. I've seen a bent compression release mechanism, slipped timing gears and broken chunks of metal that would cause the same type of intermittent jams. Nothing, just very clean engine internals and everything freely turning. I sealed it back up, put it upright, and pulled again. This time there was grinding rather than a jam. I pulled off the fan shroud and found the culprit -- the missing metal wing nut was stuck to the flywheel magnet. Depending on the last position and jarring, it would sometime hide behind the flywheel or pivot out and jam against the case or magneto. Once it jammed, it would stay jammed until moving it somewhere for service would allow the flywheel to move backwards enough for it to pivot out of the way.
On one i had a bolt come out on a cover plate behind the flywheel and it busted the coil wire mounts out of the block that held the coil that powers the light. Oil all over. welded the block holes and sold it.
@@carmichaelmoritz8662I found the same thing on a Tecumseh snowblower motor this year with the same fix.
Dang it. Nope, I've never seen that happen before. Great video Taryl
You really know your shite !! Should've shown how you fixed it and got it running again !! Wwooooooooooooo ! Love it when you holler !!!
id love to see the rebuild.. but I suspect this one got a repower.
That's some good detective work there.
Taryl is always entertaining AND informative. Love the channel!! 😂
Happened to me on my opposed twin Briggs. One of the three tiny bolts rattled loose and got stuck. Thankfully it didn’t hurt the valve.
Thread locker after that.
thread locker aka superglue, the trick to removing thread locker is to heat up the shmoo...hot engine super glue...i'd replace that thread locker with a nylock nut fast, if i was you.
It’s amazing how it got through the carburetor
It's a carburtraitor. !!!!
Amazing discovery - Tks for sharing.
Another good one Terrell
Damn Taryl- I was going to guess sabotage or conspiracy but you solved the case!!
I've never ever saw that before, and there's my Dinner. Thank you guys for the video.
Taryl Solved the mystery. No Doubt About It
So entertaining, I don't realize how much I am learning! Also, I've been getting a few strange looks with that "I Bleed Oil & Gas" hat - and I like it!
I haven’t seen that particular fault so it is very rare, something to add to the personal knowledge base. Cheers.
I had a jd L130:with 23 horse Kohler, ingest a ball bearing…similar deal….worked its way into cylinder and beat the crap out of valves and piston, until cylinder quit firing…fought with Deere engineering trying to get customer warranty but they said not used in engine, about a year later had another L130 and a 23 horse kohler that I was servicing, different customer, found ball bearing loose in air cleaner, come to find out there is a port in air cleaner for a hose that Deere machines don’t use and instead they block port with this ball bearing and they work loose and fall out ! Since then I put a dab of ultra black on end of port if ball bearing is still present, a lot of them are gone ! Love the channel Tarryl
The spot weld came loose. I better check mine . My Briggs is 30+ years old and still in service.
I had a Kohler vtwin that kept filling the crankcase with fuel. I kept thinking it was the needle and seat on the carburetor. Come to find out it was the fuel pump on the valve cover that was leaking into the crankcase.
I found that a lot on the outboards from using the ethanol: it would eat right through the fuel pump diaphragms!
I have a Krohler Command on my welder and that bolt looks a lot like one of the bolts that holds the carb air cleaner plate to the motor. After cleaning out the carb I was worried these might come loose and get sucked into the intake so I cleaned them and put used blue loctite when reasembling. Ok, just saw that it WAS the bolt.
Detective Taryl...you are AWESOME, man!!!!
Wow, good one - mystery solved! I’ve seen those red straws that Tecumseh used in their push mower carburetors fall out and get stuck in the intake before but not a big bolt like that. That’s one for the books!
I have learned a lot from this man and I'm very thankful
I once had a K321 air cleaner screw suck up into the intake and when I noticed, it was missing, I took the head off and found the screw stamped into the top of the piston.
The next time I have mine apart.. I'l be welding that stud. lol.. I have a couple of these Kohlers.. One on a mower and one on a big gas welder.
Had an Iron city beer with bill Beelby tonight, wasn't too bad probably won't find it around here anytime soon but we can get Hamm's.
Same thing happened on a Snapper 1855 with the Onan B48 engine, one of the three screws holding the air cleaner to the carb came loose, went straight down the hole and got lodged holding the intake valve open. No real damage, pulled the screw out, used blue locktite, star washer and split washers on the air cleaner screws. Engine has been running fine ever since. The screw was smaller than what you found.
TRIUMPH SPITFIRE, lost the air cleaner spacer on my spitfire,(40 years ago), it ended up in that exact place, caused it to cut out intermittently, loved that car. Don't ever sell yours, you will miss it forever.
Well, I've seen a lot of those engines and I've never seen anything like that. Wow, keep up the good work. Love your videos Thx.Bry
My first thought when you showed the threads was an air cleaner stud, Do I get a Kewpie doll?
I was working on a go cart with a 5 hp Breaks and Scrapum engine, so I did a tune up on it and me and my young son who's riding on my lap proceed to scream down the alley on it and the throttle stick wide open on it and the cross street of said alley was coming up fast and would have wrecked the cart and us as well so the option at the time in my mind was to reach back and pull the spark plug wire off which I managed to do and got the cart stopped in the nick of time and then we pushed it back to the house and on further review one of the three small screws that attach the air cleaner housing to the top of the carbutraitor had vibrated out and hung the throttle butterfly open so I took the other two out and applied some locktite to the thread and reinstalled the air cleaner plate and then I wired in a kill switch (toggle style) into on of the steering wheel spoke holes to prevent someone else from being possibly killed, so there's your mystery solved and there's your dinner.
I saw an engine in an early 1950’s John Deere MC that one of the valves broke off just under the keepers. It ran just long enough to bend the valve back around on itself. It was a customer of my uncle’s that said that it “went clunk and it stopped.”new valve and valve seat and it was running again.
This appears to be a bad projection weld. I specialized in automotive resistance welding for 46 years, and this looks like it was setup for failure. It is common for manufacturers to select a projection weld stud where the projections are too small. Ideally, they must be at least 60% as tall (before welding) as the thickness of the metal they must weld to. If they are successful, they will be stronger than the sheet metal they are in, and would rip a hole out before failure.
I would suggest every one of these get a "repair weld" on the bottom side with a MIG welder, before the air cleaner stud drops through the intake manifold. Your customer's fix of an SAE bolt jammed through a Metric thread (homemade loctite) is an excellent fix, but he shouldn't have had to do it! Further it looks like the air cleaner stud stayed in the manifold and ruined the other valve's rocker stud before it migrated to this one!
In an automotive application, this would not make it very far down the assembly line before it is recognized as a bad process...
That was a big mystery you and I learned something from this which we had never seen before this was kind of interesting
Great detective work, Taryl!
You are Awesome!
I just went up one size on bolt for broken rocker arm hole... yes a little drilling and taping of course 😁
I have seen this before working on Car Engines. V8 inline 6's. The Bolt sang, And I can't find my way home,,, Traffic, Steve Winwood?
That is crazy mystery bolt that belongs to air cleaner. Awesome short vid!
love you guys...just like giving u hard time...dupas
CRAZY! Thanks for the great vid Raymond Burr
I remember my buddies story of when he went to the proctologist for his exam the doc had accidentally left the door to another exam room across the hallway open and during the other guys exam the doc pulled a giant bouquet of flowers out the dudes butt. The guy yelled and said where the hell did that come from doc! The doc just politely says to the guy how should I know where they came from there's no card with em.
@@thekingsilverado3266 why is it impossible for that joke to work any other way.
@@carmichaelmoritz8662 Jokes are just like an ignition switch. They only do one thing. And It either works or it don't...
I thought Elkskins was the wingnut...😊
Some wild stuff right there Taryl !!!
Nice lol. I've seen plenty of old Kohler K series engines suck in the small air cleaner screws but never seen a ohv Kohler suck in the filter stud. I've fixed quite a few stripped out rocker studs with threaded inserts. Just make sure that ya put Red Loctite on the insert and the stud. They don't ever need to be removed so I use the good stuff.
Excellent work Mr.Burr!
Detective Taryle ,been there seen stuff like that, thumbs up, great video, ive found little washers dropped down the intake
Had a 700 series Briggs lawnmower that has the plastic intake break off inside and wedge in a valve.
It looked ok from the outside, but inside a piece broke loose.
Also, I found a piece of a rag stuck in a valve. How it got in there, I don't know. Maybe someone had a rag in the air cleaner, and a chunk got sucked it while pulling it over. The only thing I can think of.
Always like watching and learning Taryl 👍🏼
That’s a good one hopefully it didn’t damage to much…👀👍👍
You are the detective of the year!
This was a really interesting one and midweek no less.
😊freakin amazin.😊😊
That one was good, Taryl. I enjoyed that!
Great detective work, no doubt about it.
Oh man, I was really scared 😱, but luckily the mystery was solved and I can sleep again in peace ✌️
A great finding for sure!
That was a good one. Unbelievable that a bolt worked its way into the valve channel.
Good one, Raymond.
I've had this happen twice in the same engine. I can't find any bolts missing. Both times left the exhaust valve open. On a briggs opposed twin. Same type of bolt about 7 years apart
That's the first MAGNETIC ali-mium I ever saw TARYL,,, you sure that wasn't steel??😮
2:53 That bolt looks like a stud from the manifold.
I had that exact same issue happen on me, but instead of on my mower, it did it on my 1973 Plymouth Satellite Sebring's 318 v-8....had to do a top end rebuild because of the Bolt that fell out of the breather holding bracket.
That is pretty on an amazing! to this on a washer pump had a junk drawer all up and it’s pipes.
On Breaks & Scrapem opposed twin engines, I cut a length of grade 5 1/4"c bolt, thread & Loctite it in where the stock screw goes so i can use a Ford air cleaner wingnut to hold the air cleaner cover on. Don't need no narry nothing but your zipper flippers to check conditions of the filter.
Good job
Wow! Whooda thunk it!
Good work Taryl 👍
Amazing
Wow. Thanks for the video
i knew what it was as soon as you showed the bolt i have had 2 or 3 ive repaired from the air cleaner bolt.. i also saw an engine trashed from a carb butterfly screw
The intake will eat anything it gets fed.
I've seen several instances of smaller intake/ air cleaner screws making the trip to to see the piston. My neighbor had it happen and thought someone had sabotaged him...
Thanks Taryl
So was the stud originally spot welded in or just pressed in with the metal around the hole crimped in around it? I work at a factory that does auto, truck, and appliance stampings. Some of the parts have a 'clench nut' pressed in. Made to hold long enough to tighten the initial assembly.
Great video
Great video Taryl, but I gotta' BOLT !!
I had that happen to a Briggs opposed twin. Previous owner dropped a carburetor air corner screw into the carb and it got sucked into the cylinder head and held one of the valves open. Stranger things have happened.
It seems that they only pressed it but did not apply enough current and/or for enough time for the two pieces to melt together. In the 21st century you would expect a computer monitoring the welding current and other parameters to know if the parts are being assembled correctly, I mean good enough to survive the warranty period, now there can be lot of engines and spare brackets with the same fault...
years ago had a John Deere rider come into the shop with an engine knock. It had a single cylinder Kohler K Series engine. Took the engine side cover (pan) off and found what was left of a red shop rag. It had plugged up the oil pick up screen causing the engine to starve for internal oil lubrication. Removed all the shop towel remnants, and put it back together. The knock went away and it ran fine.
That was frigging cool.
Taryll is awesome
That's wild that he replaced the screw after it fell out but before it got to the cylinder head 😂 I would have been so confused as well
I was close, I thought a bolt that was supposed to attach the loose intake. A cookie for me...
How crazy is that
OK Ray, good find!
It was a combination of no maintenance, just emergency patches and not proper repairs. Thanks for this one in a million report.
The guy must have gone nuts looking for the missing bolt.😂
Yeah I've seen it before but the bolt in my case got passed the valve and embedded it self sideways in the piston and ruined the head!!
NO WAY! The mower's owner should be buying lottery tickets (better odds).😂
Journey ! Someday Taryl will find you..........😂
"Small engine pundit," LMFAO.
i seen this about six time's . but i seen it on two engine's the Kohler engine's the v-twin's with the larger square air box . also the brigg v-twin Vangaurd with the square air box . only on the horizontal engines . i think it caused by the rubber engine mounts being bad causing it to vibrate really badly .
Fun stuff
You don't want to be Raymond Burr, he was on of those funny fellows.
But a great lawyer !!
Similar thing happened to me with an Onan 24 HP on a wheel horse zero turn.
reminds me of the time a friend of mine changed the oil on his car and when he went to start it, it just turned and turned and turned...no spark and no run anymore....I pulled off his valve cover and there was a tiny 1/4'' drive 5/16" socket stuck in the valve body....where the heck did this socket come from?????....find out he used a nut driver with a socket attached to it to pop the foil seal on the top of the oil containers and the socket fell off the driver, into the oil container and into the top of the engine.....ended up needing a timing belt and top half of the engine because of interference fit and valve hit top of piston etc...lesson learned by him about breaking seals on oil containers...this was back in 1985...LOL...mystery solved!!!!
At 3:34 3:55 the old HAND IMPACT WRENCH!! I've been surprised on what a motor will ingest , must think its diet is lacking iron!
That happened on my 2003 3.5L Impala. pulled the stud out of the head. got a kit from time motion tools, came with all the tools to put in a heili coil
