Nicely done Donny. What a shame, all because someone didn't maintain it correctly. I had a call once, brand new B & S. Visited, and I couldn't pull it over at all. Checked the oil level and it was THREE INCHES above the max mark on the dipstick. It was hydrolocked. There was a one foot wide black streak of oil on the garage wall. Customer demanded to know what I was going to do and wasn't happy with my response. All you have to do is read the book
I noticed how dark the oil was in the sump and in your drain container. However the oil on the DipStick was New clean. Yes, someone added oil to the engine after the Rod broke or it would have mixed with the rest of the old oil. Too bad, like you said I too feel like they are good engines.
Thanks for all the great videos, Don. I have a Cub Cadet 28" snow blower with that same engine. I bought it in November 2016 and it's been great. That 357cc engine can easily handle the heaviest wet snow. I do all the regular maintenance on it in September, like changing the spark plug, oil, lubricating everything and give it a coat of ceramic wax to get it ready for the season. It starts up on the first pull every time and looks brand new.
Excellent video. It puts me on track to remove and clean the carb which for the first time ever is probably clogged due to me not emptying the fuel tank and not runnig it dry last season.
Thanks Don. A tear down to show what the cause is. This is a Cub Cadet so a nice thorough and explanation was nice. You pulled the cord to listen for the sound of the engine. The spark plug trick to check if piston is moving. I love watching these tear down videos, keep em coming. We are all curious what the cause may be.
I had a snowblower and a lawnmower both with Powermore engines. Both of them worked really well. They started easily, had plenty of power, and ran smoothly. I now only have a small yard and front drive, so I use an electric lawnmower and I just shovel my snow. Thank you for the video!
As far as Briggs engines are concerned, I had a John Deere riding mower with a Briggs. It lasted a little over 300 hrs, before I started having issues with it. I serviced it religiously, changed oil & filter, along with the air filter, and lubed it every spring. I'd also check the oil before I used it. It got to the point that every time I'd use it, I'd have to add a quart of oil, and about every 3rd time, I'd have to clean the spark plug. It smoked like I was spraying for mosquitos! Fortunately at about the time all of this happened, we moved & I needed a bigger mower, so I bought a ZT mower with a Kohler mower. Love your videos, very informative.
Maintenance is key for longevity for any engine be it in a car or small engine..The proof is exactly what you just shown in the video Don. Well done sir..Happy New Year.
I have a Yardworks 30", with the same engine for the past 15 years. I have a 1000 foot driveway out in the country. Never have had an issue and never used the electric start.
I had three engines in 2023 from customers that ran it out of oil and the engine connecting rod broke. It happens, so always check your oil periodically.
It sort of makes me wonder if there's a flaw in the engine's design that causes it to somehow use/leak excessive oil. I have a snowblower with a Tecumseh 10hp Snow King engine from around 2005 and it very rarely needs even a bit of an oil top-up between oil changes
I have that same motor on my cadet. and I love it...also I put a fuel shut off on mine....not sure why they dont put one on all snow blowers.... thank you great Video...
Hi Don. I have done a bit of work on the small Powermore engine and found it about 3 times as difficult to work on compared to Briggs or Tecumseh. I have not seen one blow up like this one but a customer's Tecumseh had the carb bolts fall out while the cover held it in place with the result of engine over rev from to much oxygen and it broke the connecting rod as well.
I have a Cub Cadet 30 snowblower, knock on wood no issues with 420 cc Powermore, it's a beast in heavy snow, bought in 2016. I would never run it low on oil. Another great video Don. Happy New Year
HI Dony, Thank you for the your time in showing us the internals of these Powermore engines. Worked on a couple myself..I just think these are great engines but in some way taking from our economy, in that manufacturers are putting the motors on at a cheaper price but charging the same price for the whole unit. Briggs and tecumseh have been around for ever and some still going... thank again jp!
I don't mind tearing down for educational purposes, but usually I just stick a screwdriver down the sparkplug hole to see if the piston moves or not. And it never ceases to amaze me that people will spend $1000 or more on a snowblower and then not do even the barest minimum of maintenance on them. Stabilizer in the fuel and check the oil before you run it and small engines will run damn near forever for the amount of time most people use them.
1. Unknown part is the counterweight. Reduces vibrations. 2. Very good engine. Never seen fail except with low oil. However, valves do need adjustment to restore compression to full in most PowerMore engines. Valves gap 8000 and 10,000. To me, that is poor metallurgy - deliberate? I can't say for sure. This could also be due to the fact that most owners do not change oil for years. Oil keeps thinning out (from unburnt gases passing in larger amounts than lawnmower engines that do not face load like snow blower engines) therefore, oil level will appear mostly normal or close to normal in snow blower engines brought in for repair, but not lawnmower engines. You will find the same in generator engines used near full load. 3. The only bad thing in this engine (and all PowerMore engines) is that a fuel cut was omitted, in my perception, deliberately. A fuel cut off valve can be installed on this engine too (possible in all but one PowerMore engine). A hole needs to be made above the recoil starter plastic cover (in this 357cc engine), and a straight Briggs and Stratton design fuel cut off valve can be installed. Before you drill the 1-1.25" hole, check where the recoil starter handle will rest. The hole will start from just ahead of that so that the protruding red knob of the cut off valve stays clear. We install this valve on all (but one) PowerMore engines. 3. Less than 1% of PowerMore engines at my shop are of the 357cc type. So, thank you very much for sharing this video. 4. Your observations about the Briggs engines are entirely correct. 5. Every single North American small engines equipment manufacturer, including Honda, is hell bent upon early obsoletion in every engine and equipment. In Europe, there is a 40 million Euros fine on such tactics. Over here, even owners manuals are deliberately misleading to ensure the same objective.
Looks like somebody had fireworks a bit before New Year's Eve this year! 8^) I also suspect this was a result of low oil causing the rod breakage. The aluminum schmear on the rod journal is a dead giveaway. I used to see this about three times a month on the old B&S 3 1/2 hp mowers I serviced for clients. Great engines, lasted an incredibly long time - IF the oil was kept filled. I had a saying for the clients to memorize - "once low - she's gonna blow!"
I have the same problem not beeing able to see the oil level on the dip stick. I pulled the dipstick and did a light sand plasting on the back of the cross hatched section. Now the oil level is much more visible. The oil stays in place rather than running off quickly.
I have the same engine on my MTD machine. It's been great - very reliable, but I look after it. I've owned mine since 2013. Shame to see good equipment abused.
Good video. My dad taught me about mower engines and I guessed broken rod at the very first of the video. I watched all the way through just to find out if my memory is good from 55 years ago. It Was.
I have the same engine on my 12 year old snow blower. I did the donyboy73 anti surging fix on it. With reasonable routine maintainance it's been reliable as gravity. Starts the first or second pull every time. The odd looking part is a rotating balancer to minimize engine vibration.
I have only ever seen blown engines due to lack of oil, or a problem with the throttle/governor causing it to run wide open and over-rev. What causes the Briggs & Stratton engines to spontaneously blow up? I always considered them a pretty well made engine. Interesting that they put a harmonic balance or rotating counterweight (the part at 9:39) to reduce vibration. The old Tecumseh engines shake like a shitting dog and are always missing nuts and bolts, those too were indestructible and I only seem them blow up due to lack of oil.
I have a Troy Built 2410 Storm snowblower that I bought at Home Depot brand new in October of 2020 and I only run non ethanol TruFuel in it and haven’t had any issues with clogged Jets or water in the fuel so far. The PowerMore engine starts easily and runs well, but it surges at 1/2 throttle and surges less at full throttle and it has done this since the day I brought it home and started it for the first time. I have heard that surging is common with PowerMore engines and it won’t hurt the engine, but if the surging bugs me enough I can take it to a repair shop and have them fix it for $200 or more or I could buy a brand new carburetor from MTD and swap it out. I would really appreciate your advice on this and take care.
I think they’re pretty good engines to Donnie it’s just a shame how somebody can neglect an engine and how much they’re gonna cost to replace one I’ve seen the crack in it that made me sad nice job
Just curious if this engine is a Loncin? I just bought a used Dirty Hand Tools Snowblower and it has a Loncin Engine, seems to work well, for a smallish engine has lots of power, and reviews seem good on the brand. I haven't had it long enough to really say more, waiting for some snow, were having a very unusually warm winter season so far this year.
Another great video l do have a briggs from 2009 and I do check oil level before starting and also change every season and so far so good the only thing that has gone wrong is the gear case exploded but thanks to your video on how to rebuild it everything is going strong thanks again for all the great video's
I have an older Ariens SB with a Tecumseh engine and I check it before every use, and I can’t get it to burn any oil. Always Ned’s up reaching the change interval before adding is needed. Scary thing is this engine holds a bit less than a quart when full.
Merry Christmas Don another great vid. I have the same engine on my cub.. change the oil in the fall. Never have had an issue. Stats usually on the first pull. It's a really fine machine. About 10 yrs old
It's a shame for a good motor to be shot because you didn't check oil. I check every time i start tractor or the lawnmower very good video thank you and a HAPPY NEW YEAR'S
I don't know about this engines, but I do know the name Briggs & Stratton. Not that I've used them, just that know they exist. What surprises me a bit is you saying that B&S are kind of more prone to breaking down thant the ones I don't know about. I mean, whenever I've been "window shopping" for engine powered things for me, the B&S engine always costs a little extra and one would hope that, being a well known brand, it would be sort of a warranty. Maybe it's only with snowblowers as you repeat? Thank you for your videos, there's always something to learn.
Thanks Don. I have heard a lot of bad things about Briggs engines from the last few years. Have a great new year, and all the best to you and yours in 2024!
Those engines are huge, I recently got a 3 stage Troy Bilt in for a locked up shifter and it had one of these on it, only difference was it had a bunch of Troy Bilt stickers on it.
I've only seen Rod failure from no oil or at least below the min level for the dipper. Briggs seem to have an additional failure mode of Cams breaking while Kohler and even most popular clones like Powermore are better than Briggs and Honda (though a lot of people will find the latter preposterous). Splash lubrication is nothing like car engines but both are known to throw a rod with no oil.
Wow, you have 98 answers to your question Dony, people don't read the comments. Anyway, my question is why the oil level was so low, it's not normal, was it burning oil ? it's not an old motor ! Bonne année Dony !
Stated in every manual that came with any 4-stroke engine ever: "CHECK OIL BEFORE EACH OPERATION". Lol Nice tear-down and video, Donny. And have a Happy New Year! :)
Hello, was wondering if you could possibly help me, I'm searching for a transmission cable for my snowblower 30255-212E is the model number..I cannot find one anywhere the snowblower is 9 yrs old. I've made calls and asked my local repair shops and nobody knows where to locate one it's a pow r kraft brand snowblower
Those PowerMore Engines are built tough, especially with the use of roller bearings and the steel sleeve. I believe they give the old Wisconsin engines a run for the money in reliability and longevity.
I always thought that snow-blowing is generally very abusive on my my MTD engine, on my 24 in two-stage Cub Cadet Snow Thrower - especially when the snow is thick and slushy. But, I am attentive with the oil changing.
Loved the video. I have used your knowledge through UA-cam to repair many snowblowers. This is the first time I have seen the inside of the engine - very interesting. Keep the videos coming! Steven from south of Orillia.
These engines are manufactured by Zongshen. They are a motorcycle manufacturer in China just like Loncin. These Chonda manufacturers copy Honda and both motorcycles and small engines in a similar configuration too. I’d still prefer the Honda though lol. (Engine doesn’t blow up when oil is actually a millimeter above add line. It was obviously significantly lower and was added)!
How about Tecumseh, you did not mention them Don? I have an early 90s B&S mower and it seems good but made in the US. Also have a craftsman with Tecumseh 5 hp mower given to me that has plugged up fuel system but engine seems ok. Prob also made in US. Noisier than hell but no smoke or knocks.

@donyboy73. Feliz 2024. Gusto nuevamente ver Tus videos!!! Gracias por TU entrega y por compartir Tus conocimientos.
Love watching you.
Reason I watch your videos is because you waste no time getting to the point and no bs talking
Thank You and Wife 😊❤
No, he does do some "BS talking"; you, he, & the rest of the majority are just too harmed & corrupted to notice it and/or stop doing it.
It's the rotating counter weight to reduce the vibration.
I'm surprised he didn't know that was the counter weight
@@jjyemg2397He knows exactly what that is, trust me. He is just making conversation. 🤔🤔🤔🤔🤔🤷🏿♂️
Harmonic balancer
Also known as a balance shaft.
He just said that to generate comments. See, it worked.@@jjyemg2397
Nicely done Donny. What a shame, all because someone didn't maintain it correctly.
I had a call once, brand new B & S. Visited, and I couldn't pull it over at all. Checked the oil level and it was THREE INCHES above the max mark on the dipstick. It was hydrolocked.

Someone a long time ago said, “... an Ounce of Prevention is worth a Pound of Cure.” That sure applies here! Thanks! Great autopsy video.
Good day Yes totally true. I remember many yrs ago my dad keep oil in it.
Too bad Thanks
Informative no stutter no “um’s” means he’s well prepared and editing pro. Just a wealth of knowledge

I was just going to say the same thing, mine runs like a champ too.
I have the same engine (357cc) on my Troy-Bilt, and I agree about its power. Mine doesn't even bog down with the end of the drive snowplow pile.
I've got 2 of them they start every time first pull. I do 6 driveways and 5 businesses. Customers are always happy
You would be the type of customer that I like!
The part that you removed looks like a counter balance shaft . Smooths out the pulse ( vibration) of the engine.
Excellent video. It puts me on track to remove and clean the carb which for the first time ever is probably clogged due to me not emptying the fuel tank and not runnig it dry last season.
I always check the oil in all my lawnmowers and snowblower engine's before starting them
Thanks Don. A tear down to show what the cause is. This is a Cub Cadet so a nice thorough and explanation was nice. You pulled the cord to listen for the sound of the engine. The spark plug trick to check if piston is moving. I love watching these tear down videos, keep em coming. We are all curious what the cause may be.
Counter balance shaft for smoother operation. Great video
Great video, Dony. However, Tecumseh always got my vote back in the day.
Thank for your help

Those motors don't run in a dirty environment, if the oil gets changed they should not be using much of any oil !
Counter weight,looked good,helps balance the engine from viberation
Great video Big D. Just bought a CUB. I will make sure the maintenance on mine. Thanks
HI Dony, Thank you for the your time in showing us the internals of these Powermore engines.

It’s a counter balance shaft to stop a lot of vibration, they use those in a lot of vehicle engines.
I have the same problem not beeing able to see the oil level on the dip stick. I pulled the dipstick and did a light sand plasting on the back of the cross hatched section. Now the oil level is much more visible. The oil stays in place rather than running off quickly.
The Nomenclature for that part is a Counter Balance shaft, it's propose is to reduce vibration. It is common in many 4 cylinder automotive engines.
I have the same engine on my MTD machine. It's been great - very reliable, but I look after it. I've owned mine since 2013. Shame to see good equipment abused.
Good video. My dad taught me about mower engines and I guessed broken rod at the very first of the video. I watched all the way through just to find out if my memory is good from 55 years ago. It Was.
The piece you were not sure of is the harmonic balancer hope that helps
I have the same engine on my 12 year old snow blower. I did the donyboy73 anti surging fix on it. With reasonable routine maintainance it's been reliable as gravity. Starts the first or second pull every time. The odd looking part is a rotating balancer to minimize engine vibration.
great explanation , it’s a stripe search and great job 👍
Counter balance shaft.
I have only ever seen blown engines due to lack of oil, or a problem with the throttle/governor causing it to run wide open and over-rev.
What causes the Briggs & Stratton engines to spontaneously blow up? I always considered them a pretty well made engine.

I use a long #3 Phillips screwdriver when I test. Won't jamb between cylinder wall and piston

I have a Powermore engine on my Cub Cadet caster wheel mower. 4 seasons without any issues and it almost always starts on the first pull!
Looks like it was ran low or dry and a person put fresh oil in that is why its so clear. Great video
Counter-balance shaft. I have one in the Yamaha golf cart I did a fix-storation in.
At 9:19, there is a bolt lying in the bottom of case is it a connecting rod bolt that came out?
I hope you had a Merry Christmas and, I wish you a Happy New Year to you, and your wife. 🎄
Joyeux Noël et Bonne Année. 🥂
You could Tig weld that hole in the Block, but that metal impregnated puddy would work well also.
Merci Don et bonne année à toi ainsi que ta famille 🎉🎉
very informative. good job brother 👍
Great job Dony. I didn't know the club cadet was that good. I also always found the Briggs & Stratton engines had a great name.
I think they’re pretty good engines to Donnie it’s just a shame how somebody can neglect an engine and how much they’re gonna cost to replace one I’ve seen the crack in it that made me sad nice job
Just curious if this engine is a Loncin? I just bought a used Dirty Hand Tools Snowblower and it has a Loncin Engine, seems to work well, for a smallish engine has lots of power, and reviews seem good on the brand. I haven't had it long enough to really say more, waiting for some snow, were having a very unusually warm winter season so far this year.
Another great video l do have a briggs from 2009 and I do check oil level before starting and also change every season and so far so good the only thing that has gone wrong is the gear case exploded but thanks to your video on how to rebuild it everything is going strong thanks again for all the great video's
I have an older Ariens SB with a Tecumseh engine and I check it before every use, and I can’t get it to burn any oil. Always Ned’s up reaching the change interval before adding is needed. Scary thing is this engine holds a bit less than a quart when full.
The part you took out with the gear on it was the balancer shaft!
That piece is a counter weight. Thanks for the video.
Great tip with the screwdriver. Thanks
Merry Christmas Don another great vid. I have the same engine on my cub.. change the oil in the fall. Never have had an issue. Stats usually on the first pull. It's a really fine machine. About 10 yrs old
It's a shame for a good motor to be shot because you didn't check oil. I check every time i start tractor or the lawnmower very good video thank you and a HAPPY NEW YEAR'S

Thank you for your videos, there's always something to learn.
That was catastrophic when it went so no "thinking" about it. I like your editing (sped up) during the mundane sequences. Happy New Year DB73
Thanks Don.
I have heard a lot of bad things about Briggs engines from the last few years.
Have a great new year, and all the best to you and yours in 2024!
Those engines are huge, I recently got a 3 stage Troy Bilt in for a locked up shifter and it had one of these on it, only difference was it had a bunch of Troy Bilt stickers on it.
you are awesome donyboy73 at working on those Engines
I've only seen Rod failure from no oil or at least below the min level for the dipper.

Wow, you have 98 answers to your question Dony, people don't read the comments.
Anyway, my question is why the oil level was so low, it's not normal, was it burning oil ? it's not an old motor !
Bonne année Dony !
Stated in every manual that came with any 4-stroke engine ever: "CHECK OIL BEFORE EACH OPERATION". Lol
Nice tear-down and video, Donny. And have a Happy New Year! :)
don't need to read, it's difficult..🤡
TY for Sharing
Dan the engine is a good brand,,,,but finding the model number for parts ,where is it at.thanks jerry
I have that same engine on my cub snowblower. It’s been great lots of power. Did you replace the engine? Or did the buy a new blower?
How goes it ? I totally agree with Briggs as junk I have the same engine but 277cc and runs mint. Like your vids
Hello, was wondering if you could possibly help me, I'm searching for a transmission cable for my snowblower 30255-212E is the model number..I cannot find one anywhere the snowblower is 9 yrs old. I've made calls and asked my local repair shops and nobody knows where to locate one it's a pow r kraft brand snowblower
Another great video. Thanks Don. ❄️ I'll try to avoid Briggs. 😊
Those PowerMore Engines are built tough, especially with the use of roller bearings and the steel sleeve. I believe they give the old Wisconsin engines a run for the money in reliability and longevity.
Please let me know your opinion on Tecumseh snow king engines. Reliability etc.
Good but don't over-rev them!
Thanks so much my 9hp has been runnung well for 24 years!@@donyboy73
Lots of nice spare parts there. Make sure there's oil in your engine.
It looks like the same engine I have in a Troy Bilt snow blower. This is a good reminder to do my pre season maintenance. Great video as always.
Yes Troy-bilt and MTD have the same engines!
Nice review donyboy love you expert on it ( ty Ron Happy Near Year @ you family to )
Thanks Ron!
Another excellent video. Thank you sir
HI.that part is called the synchro balance shaft
These are good engines and are easy to find parts for.
Have a very happy new year Don!
The motor doesnt look that old, is it worth rebuilding? I would probably want to go that route
With used parts maybe
I always thought that snow-blowing is generally very abusive on my my MTD engine, on my 24 in two-stage Cub Cadet Snow Thrower - especially when the snow is thick and slushy. But, I am attentive with the oil changing.
Don it's a balance gears like some of the kohler k series engine
Don,
Great video and explanation - thank you.

I have had many B&S engines and never had one go bad.
Good video buddy thanks for sharing take care
Loved the video. I have used your knowledge through UA-cam to repair many snowblowers. This is the first time I have seen the inside of the engine - very interesting. Keep the videos coming! Steven from south of Orillia.
Would it be worth the cost to get new parts for the engine, or is it cheaper to get a new engine?
Great video Donny
Always loads to be learned from your detailed videos.
Thank you.
Counter balance shaft makes for a very vibration free engine
These engines are manufactured by Zongshen. They are a motorcycle manufacturer in China just like Loncin. These Chonda manufacturers copy Honda and both motorcycles and small engines in a similar configuration too. I’d still prefer the Honda though lol. (Engine doesn’t blow up when oil is actually a millimeter above add line. It was obviously significantly lower and was added)!
Pretty familiar with rebuilding engines small and big but still love your videos Don.
Nice video,thanks
How about Tecumseh, you did not mention them Don? I have an early 90s B&S mower and it seems good but made in the US. Also have a craftsman with Tecumseh 5 hp mower given to me that has plugged up fuel system but engine seems ok. Prob also made in US. Noisier than hell but no smoke or knocks.
My main complaint on Powermore is the availability of parts.
Great tips enjoy watching your videos as usual been there done that that’s for sure merry Christmas and a happy new year 👍
