Easy to follow and thorough step by step tutorials do it yourself (DIY) to help you with your broken lawn and garden equipment including snowblowers.
I do my best to teach you how to easily diagnose problems the fastest, quickest and most efficient way with real repairs beyond just replacing a spark plug. These tips are for both the homeowner and shop owner.
Whether it be a handheld, two stroke, two cycle engine like a chainsaw, weed eater, weed wacker, string trimmer, grass trimmer, line trimmer, hedge trimmer, strimmer, brush cutter, leaf blower, or four stroke, four cycle units like a lawnmower, wood splitter, lawn tractor, snowblower, pressure washer, generator or a ride on mower that needs parts installed or replaced, I’m your go-to guy.
My favorite brands of spark plugs are NGK and Champion and are the ones I recommend.
I’ve been a small engine mechanic for many decades and also run my own repair shop so my videos are loaded with tips and tricks that I have learned and want to share with you. You will also find many tool and product reviews from top brands on my channel as well.
I have the largest Small Engine Repair Video Library on RUclips and the entire internet with over 1200 videos, just GOOGLE "DONYBOY73"!

Got this job to do for a friend. Thank you for saying the threads were 5/16 in the flywheel. Now I know what bolts to take with my puller!
flywheel is not threaded on. spray a lot of penetrating oil and let it sit for a few days or you might have to heat it. always wear safety glasses in case something snaps
@BriggsMower "silver" sockets are hardened and can be prone to shattering / breaking when being used with an impact gun, the black impact sockets are not hardened in the same way plus there a LOT thicker than chrome sockets and are less prone to shattering. if you get hit in the face or eye with chrome socket bits from one breaking its a strong chance of blinding you.
So nice to see someone use a puller instead of a prybar and hammer. Really professional for sure.
I did it this afternoon with just a breaker bar & 15/16. I pushed a LOT of rope into the cylinder head, that bound it up pretty good. I tapped the bar a couple times, then a good firm pull, off it came. No rust at all on the threads, don't think any penetrating oil is necessary.
Why don’t anybody tell you how big the friggin socket is that’s important
Righttttttt 😅
23 mm is what mine was
Amen dude! It's easier to get into Area 51 than to get simple info like that these days!
What torque do you use to replace the nut on the fn flywheel? Briggs and Stratton 33R877, replacement of fan flywheel only part 596832. Thanks!
Thank you sir! You always make everything look easy😂😂 I hope I never have to do that again since I am now 83 years old😊😊
N some one show us how to install a new shaft key/shear pin after Flywheel is off?
This is another great video for me, since I have a B & S 12.5hp IC engine on my 1993 42in Lawn General MTD. It's never been left outside, ever, and I blow it clean after every use and only wash it once per year.
What socket size was used to remove top of flywheel
23mm but I used a 15/16. That bolt was really easy to remove on mine.
Man, so you really gotta have the right tools... Guess I'll be spending more money.
Great videos....you really helped me out a lot....I put an opposed twin 20hp brigs on my free garden tractor... took off the bad 18hp intek with a blown cylinder....no hole in the engine so I might rebuild it who knows....but your videos helped me fix a lot of the problems with my mowers....thank you soooo much!!!!!
I have a intek engine that is a leaking nightmare. I have replaced the crankcase breather. I have tried every thing to save the engine. It is a intek v twin 22hp.any ideas.
@@f.saunders246 where does it leak from?
Good Job - I've got to change the keyway as the flywheel has spun, so this video will come in handy with the puller I just bought.
That’s a nasty looking flywheel. It’s a crime to leave power equipment out in the elements. Another great video.
it's a harmonic balancer puller
11 years ago. And we learned so much since then, like tighten the puller and crack it with a hammer
you're welcome and thanks for watching
Thanks for mentioning bolt size, I've been searching high and low and couldn't find it.
i'm just using a harmonic balancer puller, it's actually an automotive puller
An idea is to spray a little Pb blaster on the shaft that will make it come off easier....great video!
Thanks mate, great video. Removing the bolt with an impact gun and not locking up the flywheel saves heaps of time
@300Dnikon chrome sockets are to be used on rachets and black one's on impact .. they are harder material
Took some convincing, but my flywheel popped with the exact same sound! Impact wrench ftw.
It always instills a bit more courage when I see what I THINK I am doing right actually work.
Thank you for posting this.
Hey dog, it sounds like the problem I had - it was the flywheel key. It put the timing just a little off. When the starter motor turned, it hit the high spot on the cylinder and the peak of the magnet, which pretty much makes it immoveable. So it's not your battery. You need the pin to get it into alignment. Pull the flywheel and replace the pin.
Good job dude. The rope trick saved the day for me. I also don't have an impact wrench, but the breaker bar did the trick. Thanks.
Good vid Dony..Having the same prob on my 18 hp motor,Cant get it off,pains me to put heat on it though,saw where one guy uses Mapp Gas on it,might have to try that.This thing wont budge!.I bought it new in 1993 and am trying to access the one bolt to remove the starter.I have an 160 psi compressor and an IR gun,wont budge! even with lube.Noticed theres 4 bolt holes on the pancake which might suggest a special puller.Is the fly wheel threaded on?,I wouldnt think so since theres a keyway.
Thanks again dony always a plessure to watch your vids keep up the good work. I hope that your wife is now feeling better. Kind regards Steve
Spray some rust converter on the flywheel to stop it from rusting. It will turn it black with no effort.
what is wrong with using chrome sockets i use them all the time cause i don't have many impact sockets.
Nice vid by the way
Most automotive supply stores have a tool loaner program. You can "rent" a puller from them, and use a box end wrench while tapping on the top of the center bolt.
I've exhausted all methods and the flywheel won't budge, I tried the prybar underneath and hitting the bolt with a hammer, the air chisel down the crankshaft with the prybar, the pulled which succeeded in snapping one bolt off in the flywheel which I still have to drill out, I haven't yet tried voodoo or an exorcism but that may be next, this is on a 9hp brings engine on a snapper riding mower, I need to replace the ring gear, if all else fails and it has I might resort to grinding it off and getting a used flywheel.
been watchn your vids and actually used your vavle adjustment video on my briggs 14.5 ohc. but still need advice. engine will start and run for about 10 seconds and then shutsoff. coil and plug where replaced. fuel changed and cleand the carb. before cleaning carb it woudnt start. took air filter off and runs lower idle then shutsoff after about twenty seconds. how can i tell if icleaned carb correct or if its bad.
@BriggsMower They will shatter. I've had it happen and they send shrapnel flying. I use a Craftsman set as well as a Harbor Freight set of impact sockets, both work very good. Need to make sure they are black.
@donyboy73 ok thanks ill have to get impact sockets
Are you sure nothing else is damaged? I only see half of a stator there.
How did you keep the flywheel from spinning?? I tried to use my impact to loosen the bolt and the wheel was spinning with me
how do you adjust the parking brake on a craftsman 42 in model 917.271080 riding lawn tractor?
This week end I got my self a new EXMart Quest just outstanding machinery here . Have you ever work on a EXMark or any other zero turn type of machines ?
What is the size of the bolt on top of the flywheel?
Thanks for the reply Dony,I,ll keep trying.Briggs tech support e-mailed me back and said it takes Puller part #19203..I,m assuming its a tool they sell.Time to go to Harbor Freight I guess..Your vids are better then Briggs tech support.I will not be defeated! LOL.Again thanks Man.
dony can you tell me what the reading should be when a meter is put to the battery and the stator is working I have the same eng. in dc volts im getting 12.79 does this mean its charging. thank you for help
Without an impact gun, I've had success with a puller cranked up tight (or a pal with a crowbar SAFELY lodged under the flywheel), and with 2 heavy hammers: one against the side of the flywheel, hit the other side a sharp quick blow. Stay high on the side of the flywheel- so the force travels across the top.
It popped off!...I knew there was a reason my rubber mallot was sitting there staring me in the face...Thanks Dony,lube and patcince paid off.Thing I learned was with Briggs built their cheesy cowling on the motors and you RaR The cowling has a tendancy to rub,thus slowing down the start.I think I,ll stick to Red and White Hondas,,,
I have a 12hp Briggs and stratton flathead engine and there is a lot of teeth gone off flywheel and it's not
Spinning over fast enough
That will cause it not to start correct
How do you remove a flywheel?
THANK YOU
The flywheel bolt it 15/16 or I’ve seen a 24mm too
Can show how to do with out impact gun and the other tool to take out the flywheel. Because all I have it a adjustable wrench socket but no deep socket. And yeah that's it. Because I'm trying to take off the starter because its bad and the flywheel is not moving. And also I'm at the last bolt that is near the flywheel. So thats where I'm sitting at. Thank you for the response. I need your knowledge.
hi donyboy73,
my inpact gun can't put my flyweel up with the puller.
is the air to weak for the inpact gun?
@donyboy73 yesterday it was 37 degrees celcius with sun shine and today it`s cloudy with 34 degrees celcius :)
Thanks for the tip about using the rope. It worked!
Interesting. It's already done now. Will try it next time.
The flywheel was stuck with a rust weld type of hold. I could not get it to pop off. I than decided to use a blow torch to heat it up and some pb blaster. Finally it made a loud pop noise and came off.
I'm really surprised at how great my cheap puller has held up. So far I have broken one 5/16 bolt (grade 8) and puller, although bent slightly, hasn't broken. Flywheel, of course, hasn't budged.
spray penetrating fluid on shaft
Wow, I really thought that puller was gonna break. Strong puller. Puller brand?
Great video man now if I just had a puller like that how it would make life easier hahaha thumbs up
wow that one was on there pretty good!
Nice puller.
Great video, but no one has posts a vid showing how to remove the nut/bolt w/o an impact or strap wrench and no torch. I used pb blaster a few times, pipe wrench on pulley under engine and 15/16 socket with 1/2in breaker bar and the nut still won't budge. I;m just gonna spray pb blaster on it 2-3 times a day while it sits in the sun to help penetrate the threads for the next 3-4 days and see if that works, otherwise, any tips you can give?
@BriggsMower they can break during use and if the pieces go into your eyes it would sure make you blind
I did that and my broke my puller! What now???
Or how I did it at school....big ass hammer and a prybar. Plastic cover shot off and we thought it was the flywheel, and ran for cover. I've never laughed so hard.
NEVER restart the engine after doing that. It can result in hairlike fractures in the flywheel, which sends shrapnel flying as fast as shotgun pellets, seriously injuring you and other bystanders. So don't be an idiot.
@enginelover1 thank you, how's the weather in malta? 20 degrees celcius today
What dimension on the socket do you use for the flywheelscrew?
Thank’s for god information/

Hi, Could you tell me the torque settings for the 1/2 inch plastic cover bolts? I can't find it in any online specs.
Hi! Do you know the thread pitch on those two half inch bolts which you took off before undoing the nut of the crankshaft? I cant put mine back in those holes unless i put wrong ones but i dont think so.. Thank you
What's the flywheel puller that you are using? I am having this problem right now and want one that I know will work. Thanks!
Exactly how much rope do you need to put in there - I tried about 7 inches, but it didn't seem to lock the wheel? Thanks. bob
Thank you this is so helpful
what do u do,when u use th eimpact wrench n puller n it doesnt pop out?
Hi Dony, I have a MTD ride on mower with a 11HP Briggs and Stratton. The engine starts, but does not keep running. Then the battery goes weak and fails to turn the engine over. (I am thinking of connecting a larger battery). Is there some way I can check that the charging system is charging. May be by pulling the spark plug out and turning the engine over with rope with a volt meter across the battery terminals. Would I see the volts go up. Or would the meter be too slow to see any change?Thank
Dony, How do you adjust the torque on your impact wrench? I've had 3 keys break as soon as I turn my ignition on. I was told not enough torque, and the specs says 100 ft/lb. I know I did more than that and still my keys broke. I bought an impact wrench like yours ( 300 ft/lb ) max. I don't know what else it could be since there's no binding when I turn it by hand.
Someone show how to install a new flywheel shaft key/shear pin. Once the the Flywheel is removed?
Thanks
Well I hope that storm missed you we here in the lower catskills got 11 inches rain I had my septic system wash out my well is under 5 feet of water > I am on gen power and on DIAL up internet as we have no power and may not get it back for4 days The roads were washed out in both directions just today 1 lane in each direction open . The creak down from me went from 20 feet across to 1/2 mile across I had 2 feet of water in basement lost washer dryer propane tank and heater . no cable tv sucks
Thank you
Very helpful
changed keyway on same engine and still won't start.. any suggestions
It seems like they would make those easier to pull off cause when I have to remove them it takes forever
Hey Dony. Just wanted to know what type of puller you use in this video, thanks!
Didn't have any impact sockets??
Hey Dony boy73.How do you removed a B&s flywheel it is a 3hp 1975 B&S engine i cannot remove the flywheel without losing parts. can you help thanks.!!??
Define "rush". I've broken 3 different heads off my puller bolts. Wtf do I do now? Ive heated, beated, and seated it.
My puller has held up (so far) even breaking one grade 8 5/16 bolt. Flywheel still hasn''t budged.
Very nice
Good video
@shmuckseason lol, yes i noticed, i'll change it
Hi donyboy73! Very informative vids! It's helped me through my project. I am about to re-install my flywheel on my B&S 31D777 engine. Manufacturer recommends 100 ft-lb torque but my question is can I use an Electric Impact Wrench (230 ft-lb max, no other settings) to do this? Will this crack the flywheel or bolts? Thank you.
Joe Saints only use impact to remove the nut only
Those things are fragile so how to answer you? Not to make hard feelings but chances are - you have a blown fuse - a wire somewhere broke internally - the heat - then cool - then freezing - then heat - then cool - then really REALLY hot - then cool -then freeze -- then heat - then remove and install = issues period. You're lucky if it works at this point. Pull everything back off - take FINE sand paper and go over the electrical - modules [ for lack of a better word] chances are you will be spending money on a charger or a repair of the charging system. Check all wires that they are getting electric through them - then clean everything put it back together - still not working - after checking - key - wires - fuses - - then just replace
mmmm hi there ..what should a good key look like for the flywheel ?took mine of looks rather odd shaped etc but cannot find anyone to verify whether mine is in good or bad shape as yet
should be nice and straight, you can post a pic on my facebook for me to look at it

I have a fly wheel on a Craftsman snow thrower 247.889703 that won't brake loose. There are no hole to attach a puller to. Any help would be appreciated.

Hey I’ve been trying to get my flywheel off because it sheared a key and I’m having no luck
thanks for your input
Another great vid dony!
Why don't you use "never seez" on parts when putting on?
then i heat the parts
What is that half circle thing called that was underneath the flywheel? Is that what is supposed to keep the battery charged? I have a Scotts S2046 with what I believe is a similar type of engine and it's always had a probably starting from day one. When it was delivered it wouldn't start until I charged up the battery and then while it was still under warranty they changed the solenoid at least twice and I've had to replace the battery like three times so I'd really like to get to the bottom of this. Any help or advice would be greatly appreciated.
it's a stator to charge the battery, you tractor may need the valves adjusted if it's an OHV engine, ruclips.net/video/T1anxdNWf5Y/видео.html
It's only hard to start because every time I go to start it the battery is dead or very depleted.
+donyboy73 20hp intek engine.
Luigi Provencher it's called a fly wheel alternater
might need a new carb
@123ford100 drill will not work, a breaker bar will
Mine wont move, stuck!
GOT A FIVE HORSE BRIGGS AND STRATTON REGULAR LAWN MOWER THAT WILL RUN FOR A FEW SECONDS AND THEN QUIT. CLEANED CARBURETOR ANY OTHER SUGGESTIONS. IT IS THE PLASTIC CARB. JEFF WETUMPKA ALABAMA
So know the question is, since I don't have a flywheel puller nor air impact set - do I get a puller and borrow my neighbors impact set, or just give up and call Ball Equipment? lol
