twisted crank. tossin the flywheel off. got me on this one for sure. agreed tho 10 hours wtf i wonder how far out of round the hole is ??? you had no smoke for bein stuck rings...
I think the compression test told the story. The Briggs without it's CR installed, should have been much higher than 80 pounds. The scrub cadet, with it's CR installed and working, was correct at about 60 pounds.
Are the valves bent?
So you are telling me a Predator engine is now better than a B&S engine? We are screwed!
You’re awesome! I love seeing you stumped because I know you’re not going to stop until you find out what the issues are. I’m going to learn… You care about us grass 🐀’s in Georgia.
It's refreshing to see a seasoned tech struggle with a engine. It gives us backwoods hacks a glimmer of hope to keep on keeping on. Thank you Taryl
had a bad coil spin a fly wheel and keep sheering keys before, you'd think they'd either spark or not spark but sometimes when they go bad they go off-time a bit
Lawn mower shops, its fun to try to run it as a flat rate shop, he is spending all this time on one project, i have been here several times chasing strange no start issues, or machine function issues, sometimes not enough hours in the day
I cant believe that B&S would make a Clone of the qualiity Honda motor, They obviously couldn't get that right ever. So bad piston rings, they paid that quickly, PR is working hard for the mistake of the Bean Counter's!
Taryl's a Super Man! I can't believe how many times he pulled that recoil and never was out of breath or even slowed down! He might be on the thin side, but I'm guessing he's wiry as heck and all muscle! I might have been like that in my 30's and 40's and maybe even into my early 50's before I ruptured a disc, but now at 76 that much pulling would have pretty much have finished me for any kind of strenuous work for the day. ;-)
That would've destroyed me after the 1st set! LOL Either a heart attack or another round of back surgery! Taryl's stamina blew my mind!
Yeah I noticed that too pulling like that would throw you back out if you weren't warmed up at my age I'm 62... And I think he did it to show that Briggs & Stratton it's just another one of these companies that's really chins and out and putting plastic f****** camshaft ....
Taryl workout video dressed like Richard Simmons 😂
Not many channels will do what Taryl does. Most channels wouldn't upload themselves struggling but thats part of yhe process and an invaluable step in diagnosis. This channel is a treasure ❤
Love the fact he’s a Briggs dealer and still calls them Breaks and Scrap ‘em 😄
This year I refurbished a 1948 Whizzer-you know what they are-I couldn't get the engine to run right-good spark, fuel, etc. Finally I pulled the cylinder off, and found that the rings were completely worn out-put in new rings, and it runs like a champ-it had me stumped as well-thanks, Taryl and crew!
Whizzers are cool. I used to ride with the West Coast whizzer club in California.
Thanks guys! I had a great time helping solve crimes. See you next time. PS the Dunkman's donuts were great but I'm still waiting for that steak dinner.
Holy crap, my back was killing me just watching you trying to start that POFM
Stuck rings is the last thing I would have thought of. I really like using a leak down tester. It doesn't take that much more effort to use over a compression tester and it provides a lot more information. The leak down tester will tell you about leaking intake or exhaust valves, holed pistons and blown head gaskets all in one test.
Agreed. But it sucks that Taryl had to resort to a leak-down test on a practically new engine. So much junk on the market from previously solid name brands. This video's got me thinking I should rebuild an old engine in my scrap pile. All of the parts are such higher quality.
I wonder if he could measure crank case pressure compared to a properly running engine.
@@dumbluck6180 I wood a nd metal hydraulics and may tag fun
Could brim
K
Could broken valve spring cause hard starting ?
That crazy engine was even pissun ME off,... but the Lawn Mower Detectives brought some great humor to the day. Great video guys.
Thank you for sharing that problem, & the paths you took trying to figure out the real problem. That is for sure one of those hard learned most remembered lessons! Briggs quality tanked years ago, & they are barely running on reputation at this point. How do they pay your time on something like this?
Just like , stihl , husksvarna , echo and toro , ford , Chevy , GE , the list goes all the way down the line , the leaders in charge ned to fix these problems or be held accountable
I'm 31 minutes in to this thing. This is a little frustrating. I didn't see him put the B&S cam back together with decompression in the machine when he was testing the compression. so 80 psi is very low if there is no decompression on the cam, 80 is way too low to run. Should have closer to 150 psi. I bet the top end is toast from lack of lubrication. Just a prediction. UPDATE: just finished it. So it was the top end, stuck rings. I was close. I love he brought out the leak down tester. That is the 4th or 5th item we use when something like this happens at the shop. We usually start with carb (shot of starter fluid), spark plug (does it spark, is it wet), exhaust (air coming out?), compression test (60-80psi for hand start engine), leak down test if all tests come back good. Glad you got it running! Very informative as always.
Great video Taryl. Just about everything you need to know in order to troubleshoot and repair a small engine. These companies really need to STOP outsourcing their builds to China. It's real Grade 'A' Crapola!
@briggsandstratton are you guys paying attention? All the chinesium in your products are destroying what’s left of your once sterling reputation
Pieces ain't available because they've broke on everybodies elses engine too, they're sold out😂
To be clear do they care? Everyone else's engines made in China as well.... If there's no good options at least a brand name alone will sell
Don't shutdown the engine at full throttle, the engine has that big blower on it has a lot of inertia causing a lot of fuel to be sucked in with no spark. It's causing the rings to get a lot of fuel on it building up soot.
interesting...
@@michaelotoole1807 Excellent idea
Brilliant comment, I was wondering about all that black on the piston top.
Bingo !!! Carbon is what causes rings to stick.
Not always the case. Maybe in this case. But both my Kawasaki and Kohler V twins recommend shutting the engine down at full throttle to stop the backfire that is so common on this type of engine. There's an exception to every rule I guess. It works!
An old car tech showed me a spark plug lower he welded on to a air nipple. I did the same, always works! Just listen and see where the air is leaking out when you pressurize the cylinder. You don't need the vise grips on a car engine, but you will on a mower/small engine. That guy showed me that in 1982.
There's your engine on your dinner! Great job Taryl! Never would have thought of that. Especially in a new or almost new engine.
Now THIS is real mower detective work! Excellent video!
I'm still stumped why the thing had 80 lbs. compression with stuck rings. Great video Taryl. Thanks! I'd have thought that officer wasn't a rookie with how he handled that arrest. Great job Officer Faryl!
Because the leak was not a constant and sometimes the rings even sealed which is why it would run occasionally. This is a guess until someone has a better answer. Excellent work !!!
oil control rings create compression
@@jasoncook5307 That's what I was thinking. He said the oil ring was free, but evidently it can't hold the compression WHILE RUNNING without the two top (compression) rings.
The way the compression tester works is that it goes up to the maximum compression achieved but doesn’t go down again until you push the release pressure button. The leak down tester compares pressure in the cylinder on a steady state basis versus the pressure being introduced using an air line. With perfect a no leak down cylinder if Taryl introduced air at 60 lbs(it just bleeds air in) the cylinder would show 60 lbs also. However there is always some leak down past the rings in any engine. The problem is that there was WAY too much.
@@jasoncook5307 Compression rings are supposed to seal the combustion chamber from the crankcase. Oil control rings regulate how much oil is on the cylinder walls. I highly doubt any engine manual would say oil control rings create compression.
Holy buckets !!!Good video . I can't tell you how many times I've been stumped like that🤯. had quite a few CT70s do that same thing rings sticking then im pounding my head against the wall (not to Alice in chains 😆) before i Figure out whats going on
I had this same issue on an old 18hp opposed twin for the whole season last year. Every time I would go to start it, I'd have to fight it again. Starter fluid and jump starting, etc.etc.. and nothing would ever work until randomly-- it would just start for no apparent reason; drove me nuts because I'm usually good at fixing this stuff. But it ran strong I could mow with it non-stop.. but after I parked it, I would have to fight it all over again the next time. Well finally one day when I couldn't start it: it was bad enough that it was blowing pressure out of the oil fill cap.. literally spraying oil out of the cap when I took it off. So I knew that it had stuck rings after that and had really bad blowby.. Once I took it all apart, I realized that it had a good amount of grass secretly hiding under the covers when I had already cleaned it at the start of the season-- so it must have been over heating too. It's on the healing bench at the moment; I'll get to it eventually
The Healing Bench! Nice!
80 pounds with stuck rings. That oil ring was really trying to keep up and take one for the team 😂
I would have call in the Marvel Mystery oil Team for the save
God bless your Sunday Taryl, You ROCK!
I love that if something stumps you you don't give up. You always figure out what it is. And that's what I like to do makes you feel good when you figure it out. Good job Taryl👍👍👍👍
Plastic gear is one thing.. but the fact that it has plastic cam LOBES is just nuts
That’s really common. All these minibikes you see at Walmart or tractor supply have plastic cams in them. It doesn’t cause a quality problem. Had a few bikes with Chinese engines with the same plastic cam for over 10 years and still run fine. They’re not designed to overspin past 4,500 rpm’s.
Briggs & Stratton started using plastic cams about 30 years ago, actually probably a little longer than that on the 3.5 Classic L heads. They aren't normally a problem
It's usually a plastic gear that fails before the cam lobes, and that failure is usually from some other original cause.
A typical scenerio for B&S engines is fuel from a failing carburetor flows into the crankcase, diluting the oil and raising the level. Somewhat later the engine breaks a timing gear, perhaps after running great for its last few seconds. Did it fail from overspeed, the long term fuel soak weakening the plastic gear, or the high oil level putting too much load on the valve system?
A buddy of mine was telling me the other day that BMW has or is working on this thing were instead of having a throttle cable or even throttle by wire they are going further now,they will be moving the camshaft back and forth (inside the engine!!!) to lower the idle,lol,lets forgo the 10 dollar throttle cable and do something ridiculous and complex,cars are getting so insane and expensive pretty soon all you'll be seeing are old cars on the road.
I realize this video is about mowers but everyone is being affected by these crazy times we are living in,Ive heard of the industrial revolution but this is ridiculous,lol
@@dntlss BMW has had throttle-by-wire for a quarter century.
The 1998-era M52tu engine was a transition. It had a throttle cable going to the throttle body, where it moved a throttle position sensor. The engine computer read that position, and moved a motorized throttle plate that was immediately adjacent. That allowed using the new throttle-by-wire engine into vehicles designed around a throttle cable.
(There was actually a mechanical throttle shaft between the two. But it was a backup in case of a failure, using an incomplete coupling. The computer was normally the only source of throttle plate movement, but the mechanical linkage could partially open the throttle plate if the motor failed.)
The next generation M54 engine used a very similar intake manifold and throttle body, but with the throttle position sensor half removed. That engine could only be used with an electronic throttle pedal.
The recent engines control the intake charge entirely by controlling the intake valve opening, part of the variable valve timing. Initially that was paired with a traditional throttle body that was largely redundant, but later the throttle body was removed.
This skit went above and beyond. It was really funny and a nice way to start my morning
I totally agree , enjoyed it while eating breakfast. Taryl can figure it out . My shoulder cringed when I watch how many times you had to pull that rope “ it’s not starting” said in * high pitched voice . (Hubby always cracks up when Taryl talks to himself in this way) we love your show Taryl LOL Had to pause it so I wouldn’t choke while laughing at the lawn mower detectives skit too !
As tenacious as a pit bull! Indeed TarylFixesAll!
Can't get enough. Thanks man!!
Thanks for the video Taryl. I know what I am getting next time at Harbor Freight. Leak down tester.
2 yrs and I’d imagine low hrs. What junk. You know it’s an issue when parts are Nla. Great channel thanks for the laughs and education.
Wow what a great video it’s so terrible the stuff they sell nowadays 😢thanks for sharing love watching
Thank you to all service members for your service god bless
Hey...It seems everyone loves those Predator Engines! They've even put them in old ranger pickups and they actually pull the darn thing!
I know because you can get them at harbor freight everybody used to love them because they were only $100 but now there like $160 everybody builds them 212cc engines up to 20hp for minibikes
@@seanmckay3392
Yep! Man you show is funny as monkey with a beanie!
Haven't laughed so hard since 'Married with Children'!
Kept it up! Better than most shows on Network TTTTVVVV!😜😄
Thanks for making my life easier when I face my problems, Would have given up and replaced engine, I loose my KOOL easy and throw wrenches.
Great video. How do you get such high compression with such a big leak down? Stuck rings, seems to me would result in low compression
The compression was low, he removed the compression release but compared it against a motor that had the compression release installed. Without a compression release it should have been over 100 psi easy and he should have felt difficulty in pulling the engine over. The whole, "pulling this engine over is easy, I don't know why they would even need a compression release" should have made him suspect compression issues.
Enjoyed this mystery Thanks Taryl
Was thinking of minute cracks in engine or carb problem. My thoughts before watching full video. Well done Taryl.
Good to know that I am not alone when it comes to getting stumped! Thanks Taryl!
That was a hell of a lot of time to spend on that repair!!!
Time spent finding the problem just replaced the engine with a HF engine
You know Daryl, I was an green aircraft mechanic many, many, years ago. I used a differential air compression tester, not knowing how it worked, but only once did I find a cylinder not hold pressure, because it had a hole in the piston. I keep learning more and more as I watch these video’s. Keep up the good work.
Thanks for the video Taryl.
I would not have thought of stuck rings. My son would have lol but Taryl you are still the go to guy. Thanks for the video and all the great info. There's your dinner wooooooo
I’ve been saying the same about Briggs going down hill, I know the Chinese Powermore engines are mainly on MTD stuff but I’ve always liked the ones on the snow blowers. The ones on the mowers seem fine too, I think They’re made by Zongshen and I believe they’re one of the better Chinese manufacturers probably the same ones that make Predator motors. Parts can be pricey though
Zongshen also makes Champion Power Equipment engines and generators as well as Harley Davidson engines. They are indeed one of the good makers, not that I would spend the money on a Harley, I would go Honda as it's just an overall better motorcycle, if I didn't have a fear of riding on motorcycles. I feel safer in a car.
Communist made motors!
Zongshen engines are sweet they come on 4 speed Chinese pit bikes and can take serious abuse
@@evanknight3629 no experience with the little pit bike engines but I've got a Chinese dual sport(zongshen 230cc Honda ch clone engine) and it's at least survived 20,000 miles so far and still running well from what I can tell, so regardless they seem to be worth the money 1600 for a new motorcycle I've got my moneys worth even if it blows up tomorrow
I bought a Toro AWD push mower and the motor locked up and Toro would not replace the motor. Toro said if I have been changing the oil and I said yes, but I called Briggs and they said to call Toro. I took it to a authorize dealer and they said the engine was locked up and they would not replace the engine because of the oil not being changed which I did. But the manual and Toro said the oil never needs changing just check to see if it had enough oil in it. So I filed a claim with the BBB and guess
what they authorize the repair.
Awesome skit !!!! I liked the Reno 911 vibe :)
You're getting better all the time.
I can't believe how far your production value has come and I love that you have a way for your business to not only survive, but thrive.
God bless you brother.
You'll get it going bro you are a good mechanic
Fascinating video Taryl Fixes all! This is a total 'back to formula' video! You were very calm!

Appreciate you showing us how to save bucks on gaskets for these rebuilds.
Great show by the way!
Great video Taryl, keep them coming.
This all reminds me of recently when my ATV didn’t want to start anymore. It died suddenly while riding just slowly around the property… i took all the plastics off and stripped it down, did troubleshooting for months before giving up. The bike was a few years old by now, but only had about 400 hrs on it. It had spark, held compression, and had good fuel pressure. Bench tested the temp sensor, the crank position sensor, the map sensor, and tps. Bench tested the magneto and pdm. Did continuity tests on all wires, harnesses and clips. Replaced the fuel pump and injector and a whim. Also replaced the idle air control valve solenoid on a whim. Replaced spark plug, plug wire, and coil. I checked the woodruff key and it was beauty. I absolutely had nothing left to go on except for valves and clearances, rings, crank/piston, decompression valve, timing etc. but it seemed waaaay to soon for that and in order to dig that deep the engine would need to come out, plus if any of those were the issue thats total bs and id be contacting Polaris directly - so I brought it to an authorized dealer. Took them almost 3 weeks to find the issue after repeating everything i had done previous. Turns out the timing chain tensioner failed at some point which advanced the timing by a few teeth retarding the engine AND the piston made contact with one of the valves and damaged almost everything internal… piston, crank, shaft, valves, lifters, keepers, rockers, retaining plate, and jug. Plus the oil pump had metal run through it, the timing chain is compromised, and it needs a new tensioner obviously - which I hope to upgrade to a hotcams brand aftermarket. Took pictures of everything and sent an enquiry to Polaris, even tho the bike is 11 months out of warranty at the time. They agreed it was a manufacturer defect and offered to pay for all the parts, but not labour. I resent another inquiry soon after thanking them, but saying just parts wasn’t enough… they agreed again and said they’d cover all parts, plus 50% of labour. Im sooo glad I sent those inquiries and very lucky Polaris stood by their product! Its been about 3 months now since and im still waiting to this day… some parts are on back order unfortunately, but im being patient and playing the game. Total repair cost is estimated at around 5000$ total… ill still be on the hook for around 1500$ but thats a hell of a cry better than writing off my 2017 ATV after less than 500 hours of use and being left with nothing but a frame, plastics and tires!
My neighbors older Toro Recycler behaved same way, I took it apart and it was loaded with grass clippings in the cooling fins.
What I found it to be, was the head overheated and the steel valve guide got so hot that it hung unto the valve stem causing it to relocate far enough in the aluminum head to keep the exhaust valve from closing properly.
I repositioned the guide, and I was able to start it, after which it ran fine again.
Its really the only way to test piston aircraft engines. Never used a compression gauge because the differential tester did it all. Holding the prop at TDC made it easy. You would of heard the air leaking from the oil fill or dipstick.
Great tip about the synthetic oil. Thanks
There was only one Briggs and Stratton engine that was great, maybe even better than Honda in its power category and that was their flathead they discontinued back in 2017 if I recall. Best engine ever! Since then I’ve switched to Honda keeping up with maintenance not repairs.
Never thought about stuck rings. I had a truck in our shop that wouldn't start when it was colder than 50 degrees outside, no matter what, but put it in the heated shop overnight and it would kick off every time. Good spark. Good fuel sample. Exhaust not plugged. Cam/crank sync just fine. Block gas test passed. Out of desperation threw the compression tester on it when it wouldn't start, and barely marginal compression on bank 1, normal on bank 2. So when it was cold, the richer mixture was washing out the rings on bank 1 with fuel, in warmer temps or once it ran it was leaning out the mixture and the rings would seal, and compression was just high enough to get it to run. Oil had about a quart of gas in it. Customer decided they were going to wait until summer and send it thru the auction.
The older I get, the more I appreciate value, especially when I consider how expensive power equipment is these days. So what has happened to a famous name like Briggs and Stratton is pretty sad. Also, I'm just a learn by doing homeowner --not a professional mechanic -- but my common sense tells me plastic cam lobes in a high pressure part of an engine isnt a good idea.
Tecumseh used plastic camshafts on their OHV engines. As long as you don't run them low on oil or use high strength valve springs they last just fine. I've sprayed starting fluid in many junkyard tecumsehs and had them start up first pull.
No matter what it is now , everything is junk!
I kept thinking a broken valve stem valve - but you said it would run occasionally. I did notice that there was no vent on the gas cap. But didn't know if that would cause an issue. Now I wonder if that caused an increase in cylinder pressure and cooked the rings? Doubt it - no cylinder wall damage mentioned. Good work man.
Running lean for too long will overheat it I think
I am glad you and the company took care of the customer
I bought a new B&S arbor for a 1970's Simplicity mower deck a year ago, and it came with the shaft having a thick coating of hard paint. I had to use paint remover and a few hours of labor to strip it off. It's a darned shame thing have gone this south with B&S - engine failure after 10 hours. Nice to see Ronnie Jerkenstein guest star.
Amazing is all I can say. B&S probably makes double on those foreign parts so that they can pay those warranty claims as quickly as they do. Like you Ive seen plenty of stuck rings especially on two strokes, but very few on 4 strokes that had oil in them. Good Job Taryl.
I really enjoyed this video and learned a lot. B&S has really gone down in recent years. Keep up the great work Taryl and crew.
I'm 16 minutes in and before I see the whole video I want to say that these engines came with plastic crankshaft gears, if the molded key shears or is installed incorrectly (or melts) the cam timing will change every time you pull the rope. I taught small engine repair for votech and had a student with the same engine and problem. Took me a while to figure it out.
I rebuilt my dads Honda GSV190 powered Honda lawnmower which I filled up with semi synthetic oil,it has done only 5 hours of work but it will start getting a workout tomorrow since it's late spring in my area here in Australia, the rain & heat has made the grass grow like crazy.
That stuck ring issue is what sort of happened to the Intek engine on my grandfathers John Deere lawn tractor which my uncle gave him,he didn't change the oil & he kept on cranking & cranking the engine until he burned out the starter motor.
Even the local lawnmower mechanic in town thought that a broken compression release on the camshaft was a cause of the starter motor problem until he pulled the cover off the engine.
It still had compression albeit a scored cylinder & my grandfather hasn't really wanted to talk to me ever since because I unbolted the engine & he thought that I was wrong about things,I always never have a habit of stuffing things up like they did.
When my uncle got remarried 2 weekends ago he didn't want to talk to me at the wedding either,I think that it was because I got a different McDonagh whose wasn't a Green one of whose Mahers whose a Gray !
The scrub cadet had 60 pounds of compression because it still had it's compression release operating. The Briggs, with the CR removed, was actually too low, I thought.
Yes but not by much it should have had about 80-90 with not CR, but without a CR, he wasn't able to pull it at full speed either. But stuck rings might seal enough down in the hole to get somewhat decent compression, but if the stuck rings were leaking at or just past TDC, what was happening was every time the cylinder fired, and the piston began to move on the power stroke, all the pressure would blow-by. I was noticing when he had it running with no valve cover, it looked quite smoky, like it had too much blowby. It was way too much blowby for only 10 hours so I was already thinking bad rings, or scored cylinder wall at that point in the video. Look at @21:45
@@brnmcc01 He actually remarked that the Briggs was easy to pull and did not need a compression release. It was easy to pull because it had low compression, imo.
I wonder if the ringlands on the piston were machined too thin. Enough room for the rings to move initially, but even a slight bit of sludge from normal operation caused them to stick. Adequate clearance might have accommodated the little bit of sludge. That's my theory.
I am thinking the same thing. A machining problem from the factory, and the most tiny amount of 'varnish' or sludge forming in the ring land caused them to stick real quick. It's totally normal to have a little bit of varnish form on any engine, new or old, but when the factory screws up and doesn't provide correct clearance, BOOM !!! It's junk.
I'm thinking something in the fuel, some oil, additives, contaminates, old fuel, etc. sometimes additives can be very bad if the tolerances are tight and they run lean for emissions cruft.
I bet you're right.@@throttlebottle5906
Great video.👍 That would have stumped me as well, with the low hours on it.
Thanks bro for the video.. . Boys can count on you to figure it out you won't sleep good 👍..... JJ....😂
Mind boggling. I learned something about leak down testers. Thanks!
Mustie 1 would be amazed at an hour vid from grass rats
Thank you for sharing this video. I have a TORO Time cutter with the 2P77F v Twin motor. this is an older zero turn that has just quit o me.
In my "Detective" diagnosing, I ended up doing a compression test. One cylinder has 150pi, the other has 60psi, obviously, not right. I thought it was a valve, so I lapped the one with low compression.
If I crank the engine for about 3 min, it will eventually start, some times. Just like yours.
I have adjusted the valves, still not running.
So I was thinking it was the Compression Relief, or the CAM, but that does not make sense since the valves were functioning.
The one cylinder also is dry and is not getting gas on start up. IF I get it running, it runs like it is on 1.5 cylinders,
Then I thaought it must be the rings, bt since it has compression and the compression does not drop, I rued it out.
But now that you did a leak down test, I bet that if I did the test on mine, I would have the same results as your.
So, off I go to pull the motor and check the rings on the one cylinder.
The push rods would probably interchange as long as you change the tappets too. The Briggs push rod was a little longer and the tappet was a little shorter, and the opposite for the predator by what looks to be the same amount. Unless the tappets won't fit into each other's blocks.
A 212 hemi will interchange including the crank, and cam.
Non hemi have smaller cam mounts like the gx 160- 200 Honda so non hemi, and Honda interchange.

Very interesting troubleshooting process and as always an entertaining video. Thanks guys
Wow..thnks for takng the time to figure this 1 out. As a homeowner who doesn't have much time to figure these our it nice to see you take the time to trbleshoot rather than charge, replace, or junk the whole show. I knw one guy who wantd a tune up for his toro, it cost him as much as a new rather than just doin most himself
Glad to see Jaryl Jack is back in action! Also we need more Donnie!
Great episode 👍🏻
I replaced a Tecumseh snowblower engine with a Chinese made Princess Auto Pro-Point engine. Rebuilding the Tecumseh was crazy $$$.
I enjoyed this episode. You covered alot of diagnostic scenarios, good stuff for us amateurs. Thanks Taryl and I also enjoyed seeing my favorite character Jackyl, he is the funniest man in show business
It ain't got no gas in it.
Good one
Great job Taryl. Yep, that one was odd for as new as it was. I'm sure it would have stumped me for a bit also. Thanks for the great detail. T-bone

I have had the intake valve stick because of old fuel. And that is what I was thinking it was. Never thought of the rings being stuck.
Very interesting. I never knew a Briggs was a Honda clone these days ??? What the heck !
Great Skit! I liked the old heathkit GR54 receiver. Pretty sure the cover is on backwards.
It’s sad that the Chinese knock off of a Chinese made Briggs is made better or at least has a cast cam and gear. I could feel your frustration Taryl. I guess we just can’t make anything In The USA anymore ,,, I’ll just keep fixing my 40 year old stuff at least it was made well enough to be fixed.
Glad to see Ronnie's involved, of course he's always up to no good, thanks taryal, Jr and slippers , the cousin , and all we all thank you very much
I have a Poulan Pro PR621 snow blower, it came with an STB 208cc engine. I bought it around 2009, and a couple years ago the engine stopped starting, just about like this one. Now that was after quite a few years. The blower was still in pretty good condition and I had just replaced the paddles and some other stuff. So I bought a Predator 212 for $99 (before the massive inflation). I retrofitted the side cover, carb, muffler, pull, etc. from the STB so I could keep the blowers cover and controls and all that, and for example the top oil dipstick.
After looking at the engines, they are both the Honda clones just like these. I could tell they probably were manufactuered in the same plants (maybe not), even the way the laser etching of the serial was very similar but obviously different between 10 years. I didn't check if the cams were identical, BUT the side cover fit without any modification so at least the bearing IDs were the same.
Was a fun little project.
I hade a honda engine with the same problem as the Briggs went through everything like you did. Finally found the problem the rings on the piston were hanging up fixed it and it ran
I told my wife after you checked the valves and timing that this engine had a ring issue. I knew you would get there eventually...😉👍
I said the same thing to my wife, she said “Speaking of rings Christmas is coming!” It was then I knew I Fudged Up!
This engine you took the compression release out. That's why it has more compression.
This was one of the best videos I have seen. Learn a lot of stuff about motors. Thanks.
I just repaired one of the Mow-N-Vacs from the late 90's the other day. It was cream colored and had the engine turned sideways (pull rope was towards the back). Anyway, it had a 5hp Briggs on it. Ended up needing a carb service with new diaphragm and oil change. Would run while cold, but wouldn't start back once hot. Long story short, had to put a new coil, plug. $500 later in parts and labor, it ran like new. Customer questioned if he made the right choice to get the old one repaired instead of buying a new one. I told him the old ones would last a LONG time and new ones are kinda junk. Looks like this video confirms he made the right choice to repair the old one. In old machines, I put Castrol Syntec High Mileage full synthetic oil. Very expensive but lasts a very long time in small machines. Great for people who rarely do oil changes, which is basically everyone under 35.
Question : if it's determined that rings are stuck, is there a chance that soaking the cylinder with snake oil, ATF, or something like marvel could remedy the situation? This video was absolutely amazing and I really learned from it. I claim myself as an efficient grass rat, but so many times have been tunnel visioned in the wrong direction. Thank you for sharing the struggle!
The chances are that you’ll free them rings all right. The challenge now is to keep them from getting stuck again. So to prevent this from happening again in the future change the rings or even better piston and rings together. Don’t forget to break in the piston rings as you would do with new engine (5-6 hours run at minimum with first oil change after 1-2 hours)
I’m betting the customer has never changed the air in the tires … good luck getting the engine warranted
Tray did get the engine warrantied from B-S
The engines the problem not the leaf attachment
@@juniorlazaro289 I think it's a joke.... Don't over analyze it.
We didn't figure it out. But I am glad that I watched YOU find it. Taryl Dactyl Fixes ALL
I put a Harbor Freight engine on the leaf sucker and had the same problem with the muffler.
I cut the stem of the muffler in half. Then I took two 45 deg pipe fittings and welded them to the stem.
The first one leaning inwards and the next one leaning outwards. That put enough of an offset to the muffler that it didn't interfere witht the blower housing. It works great and cost only a few dollars.
Is it possible to remove the compression release altogether? (Asked 3 mins into the video, answered shortly thereafter)...would have never guessed stuck rings
That what I was thinking
5732 rope pulls later, the lawn is free of leaves!
The mower shop across the street from us has the SAME kind of issues with parts. It's nice that you've shared your struggles with us.
That certainly helped me add to my things to look at, had a Briggs, their Vanguard line, on a Cyclone rake come into the shop. Needed a carb and coil initially to just try and get it running. Mouse chewed coil wire jacket and I figured coil was shorting out through the hole in the jacket to the metal covers or head. Carb was gummed up and pitted. Get that replaced and still wouldn’t start. Found this engine to have no compression. Customer opted to not fix or repower it. Appreciate these videos as they help me better myself and skills as some of these things are not covered in trainings offered by the manufacturers.
Taryl, it seems like all of these manufacturers are dropping the ball.
I had a nice little Hustler Dash with the junk single cylinder Power Built engine. I knew the crank was eventually going to fail. I sold it and got an older mower
