Of the 1000's of "Watch me act like I'm fixing this" videos, this one is by far the most comprehensive and in-depth one. Thanks

Not only is the content of this video a great resource, but the description and times stamps should be a KZfaq standard. I don't watch these videos to get out of the Sun. I watch them to find out what I need to do to get "Back out into the Sun"! Thanks for saving me a bunch of time. GREAT WORK!!!

Yeah! Just like other people have said; comprehensive explanations of how to go through a mower, or any small gas motor. Thanks!! I have a 25 yr old murray, 4.5 hp briggs, left outside, rusty deck( still safe) but still runs great because of folks like you. Still starts with 1 pull. Gotta find a deck somewhere soon. Any how, my son says “ just get a new mower?!” I’m like, “ you kidding me! Fix something once, you get hooked! “ I’ll try to keep this thing running until it falls apart. Haha. Thanks again!

Dude, this was the best small engine repair video on KZfaq. That mower had every problem that could occur except for primer bulb replacement. I learned a lot from this video. Thank you for the upload!

Dude, this is by far the best lawnmower repair video in all of KZfaq. You pretty much troubleshooted every part of the machine and fixed it one by one. I just fixed my lawnmower myself yesterday (nothing big, just the carburetor) and it felt great, especially knowing that I saved myself $85 dollars from repair shop. I'm a do-it-yourself kind a guy and I love learning how to fix stuff. I sure did learn a lot from your video. Excellent job!

Over the past several years I've gained a lot of confidence repairing my own equipment / appliances. Having detailed information like you provided helps a lot and saves me money too. I appreciate it very much.

I never really understood timing until now. This is the best analysis video I have seen.

I know this is nine years later, but I must commend you on creating such a comprehensive mower repair video. Thank you!

This is probably one of the best small engine repair videos on youtube.

Great to have a video that not only shows the How, but the Why and the trouble shooting Process. Thank You.

I have been looking for a KZfaq video that would help me fix my Briggs and Stratton mower. I've looked at a bunch but my friend you have the best repair video out there. Thanks for providing such detail and pauses for clarification. I was about to throw my mower in the trash because I had tried everything. But because of your video I decided to try something you suggested. No one I mean no one has a video about looking into a sheared key on the flywheel. When took it apart sure enough half of the key was in the flywheel and half was left on the shaft. Changed the key out and it started up like New. Hallelujah! Thank you very much and I have shared this video with numerous friends. Tremendous help.

The way you explain the small stuff is great for those of business who are just getting started on all this! Thank you for sharing your knowledge and experience!

As an engineer, I can say this: an excellent presentation or video. Well done. Thanks,

That was fantastic. Thank you so much for making this video. My boys have their own lawn care business and they need to keep knowing how to service their lawn mowers. They are only 13 and 11 years old but they are really good kids. This will really help them to make sure they diagnose and repair their mowers. Once again thank you so much for the in-depth coverage on how to.

I was about to shell out money to fix my mower and now I know what to look for. Thanks a million.

got 2 machines that did not start tonight after pulling them out for the first time this season. It was just before dark, so did not do any trouble shooting, this guide is still the best around all these years later.

Man, you are the best , thanks to you I found the problem with my Briggs Stratton engine, the key was broken and it was out of timming. Now it is working very well. Thanks

This is the most awesome video for EVERY ONE to determine why your lawn mower isn't starting, isn't staying running or needs maintenance. The length is just about right, the info spoken during the video is extremely helpful and SPOT ON! Every lawn mower should come with this video!! Thanks, your video is directly responsible for my lawn mower starting this season! Will in Southampton, NJ

This is by far the best video I have found on how to fix the lawnmower. My mower had a timing problem. I followed all the steps here, now my mower works like new!!! Like I said, the most informative and helpful video!!!

That's a very nice lawnmower, it's a shame it was so poorly maintained. I am in the same boat, I just rescued my neighbor's old lawnmower she had abandoned in front of her house, I will get it fixed up and I thank you for your help.

Best repair video yet. I've watched countless videos on lawnmower repair and you're the first one to show me how to check/fix the timing. That'll be my next step. Thanks for the well explained video. Keep it up!

Granted I know all of these skills from cars... having such a well done small engine repair video is gold. This is beautiful.

Can't believe the haters who gave you a thumbs down. You may not be Cecile B. DeMille, but that is a well laid out, methodical video on repairing a trash picked mower. Kudos to you.

My dog perked up and glared at my phone with a really annoyed look while I was watching you sharpen the blade on your bench grinder. She made me turn the volume down!! Great video, tho. Guess I'll go get started. Thanks!!

My Dude!!! Luck would have it I own the exact same mower and your little fix it guide will get me up and mowing in no time. Had to do some part number research but helpful doesn't scratch the surface of what this vid does. I appreciate you talking like, (and to) an adult not spending 5 minutes explaining the function of a screwdriver and the righty tighty rule. One more thing I KNEW IT!!! I bought mine used as well and thought it was odd there was no throttle cable, huh!!! It'll have one today I'll tell ya! THANK YOU!

What a great video! I just picked up a free 5.5 hp Craftsman mower and was able to fix the problem with a new spark plug. This spark plug cost only 2 dollars and now I have a mower in perfect condition! Thanks!

What I do with my screws is put them back in the holes that they came out of after parts are removed. That way, you know where they are and what they go to. Awesome job on the video!

this was the best tutorial I have ever seen. the teaching skills started from the very beginning of trouble shooting to the culmination of a major fix. Great ,just Great. thankyou

thanks for the video...I knew nothing about mowers from this video I paid $10 for a lawn mower because they thought it was stuffed and I cleaned the carb, it blew smoke for 5 minutes now it works like new

I need a man like you in my life! I fixed my mower with the spark plug info you showed. Thanks!

I watched this video with great interest and , found that you did an excellent job of explanation and your trouble shooting was very clear and to the point. I just wish I could have lived near you and your family . I would have really enjoyed seeing you and picking your brains of every little detail. You are the real deal on lawn mowers. and you know your stuff. I'm 75 years old and can barely get around, I'm half blind, and have authorities so bad that I can hardly get around. In my early 20 's I just loved to tinker with small enginesI hope you continue your way in life doing what you like to do. Have a good one. By.

Good good video! Well explained! No music! No extra talking! everything to the point! Thanks for your advices regards from Colorado!😀

Great video, easy to understand and well edited. I'm sure this will be helping out lots of folks and I appreciate all the time it took you to produce.

The best lawnmower troubleshoot video out there! That Craftsman mower had lots of issues from abuse and neglect. You expertly repaired every one. Thank you for a great instructional video!

Good job! I have never been so informed about lawnmowers as I have by this thorough self help video. My wife was at my side watching as well and was also very impressed. Thank you so much.

Hands down 1 of the best how to videos on youtube. 2 small oversights that I saw. There is a washer that goes inside the starter cup and it makes a difference on how it goes in. It has a small curve to it and it goes down. It locks the cup to the flywheel and won't spin when you tighten the nut. When securing the nut you showed the coil instead of the blade brake looking for the correct depth so to speak for the flywheel to seat on the shaft. The coil should never rub on the flywheel.. Thats it for me, from 1 wrencher to another, outstanding video and you set the bar very high 👍

Just getting into small engine repair, this video has helped a lot, thanks 👍.

Appreciate the patience and time doing this blog. Well narrated and addressed the different areas that potentially can cause your mower not to work. I will be looking at an area mentioned here about the timing on my own which I did not realize may be my problem. Thank you!

This is the most comprehensive no start video that I found. Well done.

Excellent video. Touches all trouble spots on the mower systems in an easy to follow dialogue and fairly stable camera.

Fine job,very informative as well as detailed enough to show what you are actually doing. So many of the instructional videos tell you what their doing but don't show it. That mower rips through those weeds like nothing, not even slowing the motor. Great work!

you're my hero! only cut one finger broke three nails and scratched my leg...but it worked. got the darn thing to work.

My lawnmower wouldnt start today, saw this video, and was able to fix it AND mow the lawn today... Excellent video and the best part is that my mower was EXACTLY the same as this one, so I was able to rip it apart really quick thanks to you... Nice job man!

Great video, you hit all the main points. One thing you might consider adding is a comment on engines that use the blade as a part of their timing system. I tried to start one of those without a blade once and nearly yanked my arm off! Great job.

Thank you for this video. It is very through and detailed. I learned a lot watching this video. Gave me somethings to look in to on mine. I have a Troy-Bilt 34345 with B&S 6HP from 1998 it still runs and looks new. It stalled out on me while mowing and I think the ignition system is at fault. I am waiting for my parts to arrive to further troubleshoot. I just want to say thank you, I wish I found this years ago!

the description with the different times for different stuff in the video is awesome..i wish more people did this in there videos..thanks

Appreciate the commentary as the engine was being checked for problems and the steps to fix the broken key way.

Without question the best how-to video on KZfaq. Please do a how-to video on how to make how-to videos! Informative, understandable, and watchable start to finish. WELL DONE!

Thanks for the video, I have two riding mowers both have kohler engines both don't run. So I am tired of paying people and they still don't run. So I decided to teach myself small engine repair. Your tips are a great start, I've always needed the basics you shared today. Thanks again Kudos

You are the man! My B&S engine stopped running the other day. It just stopped and wouldn't start. I couldn't figure out why. It had gas, spark and compression. After watching your video, I checked the key and sure enough it sheared off. Now to fix it. Thank you so much.

This should be required viewing for anyone posting a "how to" video on youtube: No BS, no kids interrupting the video, no "um, um, um, um, um", he fast forwards through the tedious parts like taking out the screws and bolts. Clear, concise, to the point and quickly to the point. Furthermore, it is a complete diagnostic journey. I can't tell you how many "how to" videos i've seen where I shut them off 2 minutes in because they are unbearable and the poster spends 10 minutes explaining what could take 1 minute. To "familytime" send me your postal address and i'll mail you a T-handle for your tap as a thank you!

You are are great teacher. Thanks for showing all the processes clearly and demonstrating how to use the tools correctly. Just what I wanted to see!

I don't even own a lawnmower, let alone a lawn, and I still found this video to be awesome :)

Hey! Thanks for posting your video. I went through all your steps. Now, my mowers running. Something was in the carburetor. Thanks again.

Excellent attention to detail. Now let me tell you something. I love my electric lawn mower. Thing is great. It's as light as a kids plastic push toy. So you don't need no power assistance. I think even an old grandma could push it. No noisy engine. Just a sweet whirr. If I feel like stopping and doing something else-no problem. Just let go of the handle. To start just push the button and grab the handle. No struggling to start the thing EVER-NEVER-EVER. And the coolest thing of all is the smell. Nothing but sweet smelling grass smell. You really got to experience the way it smells. It makes you want to mow the lawn even more. The only fall back is the dang electric chord. It's easy to get a rhythm. Even when going around trees etc. You just work each section in squares. Go back and forth and don't go backwards. I had one many years ago but I made the mistake and sold it. Now I got one for $60 at flea market from friend. If I don't sell it, it will probably last the rest of my life.

Mine was driving me nuts. Took it apart 6 times and replaced almost everything. Still couldn't figure out why it was running so poorly. After watching your video I saw mine had the same problem as yours, the flywheel key was sheared. Thanks to your video it runs like new.

Nicely done. Very informative. I'm not so intimidated by my small engine mower anymore.

Thanks, I have this same B & S engine. Running ethanol laced gasoline, even running with Sta-Bil all the time, I know I will be rehabbing the carb some day. I bought the carb rebuild parts, a lacking inline fuel filter ( clippings always manage to get into the tank ), extra replacement primer bulbs and a few other upgrade and maintenance parts from B & S online when the mower was new. LOL, 12th year and I am still waiting.

Great video had not checked keyway , Turned out that was exactly what was wrong guy gave me the more because he couldn’t get the mower to start ! Keyway was sheared and blade was severely twisted ! Thanks for the help!

Great. I learnt a lot! Next job is to check the keyway!

One of the best edited, best narrated and most informative videos on the subject out there. Good job. Thanks!

Great video and explaining yourself!! Also indexing the vid on the desc. is another excellent touch. Many people dont have the gift of being able to teach and explain themselves as well as u. Great vid man!!

Hi There, You Done A Good Job. One Thing Everyone Should Do Is Put A bit Of Never seize On The Crankshaft Where The Blade Adapter Goes On. It Will Save You A Lot Of Problems In The Future If You Need To Remove It Again. If You Wash Your Deck Underneath ,Water will Get Into Everything. Moisture From Wet Grass Left On The Underneath will Cause RUST. I'm Not Knocking Your Video By Any Means. I Noticed a Lot Of Oil Under The Deck, Which Will Make Your Drive Belt Slip, It Could Have Been Cleaned with Some Degreaser. The Oil Leak Could Be A Bad Oil Seal On The Bottom Of The Motor Or They Have Spilt Oil On The Mower and It Has Run Down And The Blade Has Spread it as It is Going Around. The Engine Sounded as If It Was Surging a bit. ( Not Getting Enough Fuel ) Other Then That You Done A Great Job, Thanks For The Video

Really clear, concise, and complete! Now armed with enough to try and troubleshoot my chipper-shredder engine. Hope you rack up some ad revenue -- you deserve it.

I have watched a bunch of videos, your's was simple and easy to follow. I love to tinker and fix things. I have 2 mowers and 2 weed eaters to play with in the spring of 2021. Thanks again.

Wow..I am not into motors and don't even have the proper tools to fix the machine. I came to this video because my lawn mower is hard to start (it does start after a few tries) but the engine keeps cutting for a fraction of a second until it dies. Then I need to wait for the machine to cool down until it starts again. Anyway, this is the most thorough troubleshooting video I have ever seen. Excellent...and you are a great mechanic whoever you are. Gave me a few tips to try it on my lawn mower tomorrow. Thanks.

I really learned a lot about the timing and how to replace the key way, thank you for showing the repair.

You have those videos that say "it's the spark plug." Then you have people that take 40 minutes out of their life to help people that need to fix their equipment. Most in-depth video on this topic I've seen.

Nice video. That thing had so many problems it was almost as if it was a factory training machine where they broke everything conceivable! I learned a lot watching your video--thank you!

Great video. I am glad you got it running, your weeds were out of control.

This is the best repair video on KZfaq thank you so much. This was a complete study of everything i wanted to learn.

Most helpful video on fixing lawnmower engines/small engines. My son bought a cheap Honda G150 second hand and he is trying to fix it up, hopefully this video has a few tips and tricks that he could use.

Great video my man. Very informative. I have worked on lawn mowers a lot of years having to learn all this the hard way, but the way you break this info down, I believe a beginner can troubleshoot one after watching this. Good job dude!

Great video easy understandable. I also like that there wasn't any back ground music that took away from the video never understood why so many do....

Great video but if this old man might suggest. NEVER no not ever go under a push mower deck without disconnecting the spark plug. You never know when Murphy might show up. The second suggestion. If you put a spark plug in a vice, and I've done it, never clamp on the procelain. Always clamp it down on the flats of the metal. Outside of that, again great video!

You are a true mower doctor. Thanks

This video got my mower running again. Thank you!!!

Great video. I never knew about checking the timing. Now I know what to look for since my son ran over an exposed tree root.

was going to buy a new mower,but think i'll tink.thank for the class on small engine repair!!!!

Excellent!! Thanks for not using annoying background music as most people do. Very helpful video..

Hey Mon Ami here is a little trick for you , I use charcoal lighter fluid cans for adding gas in a carb. I put gas in them and just squirt a lil in the carb. Way better than using starting fluid. I have one for 2 strokes and one for Lawn mowers .

Super amazing effort on this production. I've got an old high performance mower that I spent all day on, getting nowhere trying to start it. I treat all my equipment like gold. I didn't know about the "key" thing under the pull cord. Then I remember, I have loaned it out a couple of times. Maybe somebody hit something. I'm gonna check that tomorrow, and hopefully the "timing" thing is it. If not, thank you anyway. Very helpful and useful information presented so well.

Prob best small engine repair ive seen

Very good video. Perfect for a guy like me who just wants to fix his own machines 'cause he does. I'm sure there's all kind of weird problems and little finesses that an experienced small-engine mechanic must know, but this gets me well-started. Thank you.

Thank you so much for this video, I needed a detailed video and spent two days reading and browsing. This should be at the top of trouble shooting lawn mowers! The thing that really makes this video exceptional is "what could be wrong" when you are explaining things. Love it! Exactly the info I need and want!

great stuff, showed it all with good explanations for newbies like me.

A lot of information and helpful thankyou, applied it all this morning.

I like this because he explained and show all that he was doing to repair the mower.

Great video.... Working on these mowers for years, I learned a thing or two...

Well after running to a few different places to get the right tool and the right size key, I fixed my engine. Oh I can't thank you enough friend for making such a great video. You deserve the Good Citizen Award. I'm having a beer in your honor. CHEERS! You are what makes KZfaq great. Thank you. Thank you. Thank you.

Amazing . Thank you so much 👍 I am 43, and I just learned a whole lot 😄

Great video. Clear, concise and to the point.

Excellent video! I was able to deduce the problem to be a sheared key from your video @ 6:56 which was of tremendous help. Many thanks! Sears mower, Techumseh 3.5HP.

Thank you for your fantastic video. After watching this I got my mover running. Saved me 400€. THANKS!

Love your full explanation of any and all issues that could be wrong...love the fact that you got into deep brush upon repair...a very real world situation...2 thumbs up if I could!!

That is very flattering...this is a hobby of mine to mess with things. I just enjoy working on stuff and making videos about my endeavors. Thank you.

Nice video! Thanks for taking the time to record/post it. I feel like I could get any mower running after watching it.

There is a lot of information here. Very entertaining and well done on top of that!!

PS - I too am going to have a beer in your honor this evening!!! The ABSOLUTE BEST helpful video for every one with a lawnmower. CHEERS TO YOU 'familytime' !!!!!!
