- * VISUALLY EXPLAINED
You come to mow the lawn, and your Lawn mower Won't Start? or if your Lawnmower starts then dies! I talk you through Common Causes & Fixes you can easily do yourself. So now you have that problem of the Lawnmower not starting, don't wait weeks for repair work from repair shops. Be up and running in minimal time and low cost. In times like this you may wish you had an auto mower, which are indeed very good, but my argument is that the good old walk behind mower fun to use and you have more control over when and where you have the cut!
However, there can be many reason why a lawnmower wont start, or a lawn mower starts then dies, these are some common reasons.
So, whether you are using a Riding lawn mower, Push mower, Petrol lawnmower or even an electric lawn mower, this principle is valid. Also true whether your mower has either a 4 Stroke Engine or a 2 Stroke Engine. The Robot Lawn mower doesn't escape this principle either!
If you are having problems starting your lawnmower then please do take look at my other video, where I help you get back you and running again if your Lawn mower Won't Start: • Lawn Mower Will Not St...
The principles shown here can be used for a riding mower or lawn tractor as well.

Hi guys I just wanted to Introduce to you my other Channel "Kirkman's Academy" - which i'm just getting started. It's a go-to channel for simple explanations for hard to grasp subjects such as physics, maths and chemistry etc. Here is the link: www.youtube.com/@kirkmansacademy/videos . Thank you so much for looking, and if these topics interest you then I hope to see you the there. Many thanks indeed. Craig 😊👍
After bragging to my new young sweet and beautiful girlfriend, that "I cab start anything in 15 minutes", I wasted 2 hours of adjusting everything to specs, changing condensator and breakers and not starting my 1972 MZ 150, that I knew, had been able to start easily, last time I touched it.. I ended up ditching the brand new NGK B6HS (as I reacall - at least the correct one) spark plug, and putting the old worn one back in, and succes.. NEVER trust a part, just bcz it's new..
I have a electrical lawnmower that want start it was working I cut it off to get something out of the way want start back up I don’t know how to get the top off to-get to the motor
I love my dad, but one thing he did to me as a kid still kind of irks me. He had an old lawnmower that wouldn't start. I guess he had taken it to the shop and they said it wasn't worth fixing. So I asked if I could have it. My dream was to get it working again, and then use the engine to make a go-kart. A buddy of mine and I spent weeks working on that damned thing - neither of us knew anything about engines. We took everything apart, writing down how to put it back together, cleaned, sanded, borrowed a gap measuring tool to try to fine tune the spark plug (singular). I was into electronics and so I had a basic multi meter from radio shack that we used to confirm the alternator was working, etc. We got it purring - and then my dad wanted it back to give to a friend of his who was a perpetual 'ner do well and so always down on his luck. He basically forced me to sell it back to him for $5 - that was when the minimum wage was $2.50 and my friend and I had probably spent over 100 hours on it. ...don't know why I told you all that. Just needed to vent I guess.
I just took my step dad's old lawn mower that wouldn't start because he was going to take it to the dump. He does zero maintenance on anything he owns so i figured it would be worth a shot to clean up. I just finished cleaning everything and putting it back together. New carb, filter, gaskets and spark plug. Fired up twice and now won't go. 😂 I won't even send him a picture of what it looks like now. I feel ya!
Yeah things like that stick with you for sure, especially the fact that it was your dad. I wanted a mountain bike when I was a teenager, I asked my dad a number of times for one. He got me one but ruined the whole experience by reminding me forever that he bought me a bicycle. I wouldn’t mind but he spent most of his time in the pub
If he’s still alive TELL HIM, GET MAD, sometimes people need to know when they wrong.
Accept the apology he'll never give you and move on.
Now that you are a man, you need to let him know that was messed up. Like really let him know.
I just did that, my lawnmower now is running like a champ again. I clean the carburetor and found 1 of the holes with yellow stuff, clean the tank, let it dry & fill again starting at first pull 👍🏻
Great video. At my house I have 4 lawn mowers each with their own issues. I'm a woman who is taking charge to get one of them running so I can mow my large lawn. Sometimes you have to figure things out for yourself. The men aren't always around or willing. Your videos are so easy to understand. Thank you

I just fixed my lawn mower today!! Thanks to you!! 🎉
Thank you for posting this! That was so satisfying! 🦼
Thank you for your kind feedback. I really appreciate it. Craig 👍👍👍
I have watched over 20 videos related to lawn mower fixing. Yours is the best, step-by-step, straight to the point, and you showed how to drain the gas tank. Thank you very much for sharing. BTW, I have mine fixed after cleaning the gas tank and carburetor following your steps. Many Thanks!
Fantastic video fella, the fuel hack was just the trick, fuel was light brown coming out so very stale. Once drained worked like a dream saved me £££'s
Awesome. Thank you for letting me know. Craig 👍👍👍
I've just got to say it. The metering jet is also often plugged with varnish in a float bowl type of carb. A little bath in lacquer thinner, carb cleaner or some other hot solvent, then a wire to ream the orifice will get you going.
Very true 👍
@@TheRepairSpecialist I have a Mountfield HP185, (Briggs and Stratton 300) series that won't start, however, I did get it started a couple of days ago and gave it a good run but since then, the bugger won't start, do you think that it's still fuel starvation and maybe I was lucky to get it started initially? I have changed the spark plug but still no joy.
😝🤑
@@christopherlorenzana4507 Are you drunk or something?
NO wire. You can ruin the bore. Air - liquid - nothing hard..
Put some fuel stabilizer in the gas tank and run it for a few minutes before you put it away for winter.

Better yet, just run all the gas out of it before putting it away for winter. Then in spring put in fresh gas, remove the plug and dip it in gas and reinstall. It should crank right up.
Maybe also add that ALWAYS run your mower completely out of fuel before winter storage.
THANK YOU. I am not mechanically inclined at all and this fixed my non-starting mower. Emptied the gas tank and also the carburetor "bowl", filled with new gas and started right up on the first pull. I almost bought a new lawn mower, but figured I'd look on youtube first. Glad I did. Much appreciated!!
Thank you. I just pulled the mower out of the garage for the season. February in Florida is when I have to start cutting the grass again, after a 2 month break. New mower, worked great in November. Your video has helped me tremendously.

Funny. Where I am it's a 9 month break from mowing!
I inherited my dad's old Briggs mower and I must have it 15 years now. In that time I think I've only changed the oil twice and the same for the spark plug. That thing still purrs after all those years. I think those old Briggs and Stratton mowers are the best.
This has shown up on my feed in a timely manner as I'm about to give my lawn it's first cut of the year
I just found a petrol mower that was going to be tipped. Tomorrow I will be following your tutorial to see if I can fix it. Wish me luck.
That’s good that you are taking on that project. You will learn a lot. I wish you the best of luck. Craig
Thank you sir. Great video. Will use this knowledge to fix my old mower this wknd.
Excellent!
I had this problem last year. I will definitely dump the old fuel and buy premium fuel this time around change the plug and drain the carburetor bowl.
Cheers to happy mowing, then I will have a cold beer.🇨🇦

Thank you sir for sharing this knowledge. I was at my wit's end, I have zero experience with servicing these tools and was on the cusp of purchasing a new one. Watching your video gave me confidence in knowing that my assumptions were correct and what my next steps should be. I hope to update this tomorrow that my lawn mower is up and running. Either way, great video. Easy to follow steps and subscribed for more content
Thank you for this info, It helped me today to get my lawn mowed. Bless you for posting,
This is the best video I've seen in a while, going to try this tomorrow.
Well informed video, sent my daughter who is having mower issues thanks for your time. Wish you the best from the states
Thank you for this video! My mower started on the first pull after changing the plug and fuel.
I appreciate this video so much. I know it took a while to do it and it's much appreciated 👍🏽
Nice tips, thank you! I'll share that I had a hard starting Honda and only starter fluid would get it going. The problem was the throttle cable was mis adjusted and the choke was never fully engaged. After adjustment, it fires up with just one pull every time! It's a good idea to run a bit of SeaFoam fuel treatment in your gas to allow it to stay fresh and not gum the carb up.
Thanks for the good advice.
Worth also checking air filter.
Thank you so very much from Romania. It only needed new gas. All the best!
You're welcome! 👍👍👍
Followed the instructions and my dead lawnmower came back to life. Thanks a ton!
Awesome. Thank you 👍👍
This guy is fantastic !! really looking foward to trying to get my honda going !!! fingers crossed
Thank you so much. I really appreciate your kind feedback. Craig 👍👍👍
Great video. thank you.
i'll try these now!
Great video very informative especially for people who don't generally work on their own equipment. in my experience over the years most of the push mowers I come across will simply pull but won't start 99.9% of the time the safety lever cable is stretched or broken it leads to a small engine brake pad on the side of the magneto that acts as a kill switch its a $10 or $15 fix for a replacement and not to hard for the average DIYer to replace
Is there a video to this type of repair?! Sounds like it could be my issue
When I was a in high school in 1995 mechanic class teacher was my history teacher Mr. Moore he told me to teach the mechanic class and we had 20 lawnmower’s and my friends and me got all over them running in 2 weeks and Mr. Moore history teacher was proud of me in all my friends! Mr. Moore knew my father said Robert teach the class and I got award for teaching all got A’s
Thank you, Gent. I appreciate it.
This is one of the greatest video I've seen lately about repairing something, and I use ytb a LOT since like idk 12 years. You sir are amazing.
greetings from Argentina 😁
Wow, thanks! Craig 👍👍👍
Thanks for your help!
Excellent video. Thank you
What a brilliant informative video well done excellent thank you
Thanks a billion my last lawnmower I had to discard it because it wasn’t working now since I took my other one apart from the fuel tank and cleaning it now I see why it wasn’t working
Thanks for the information and video 👍
Aussie fuel!!! Lol. Every few weeks fuel goes bad even with no ethanol. I find whipper snipper is a problem. I bought an Aldi one 2 years ago or more. It died just after warranty. Btw you have the good model. Briggs and Stratton with a metal tank. The plastic tank has an internal fixed mesh filter inside. A few times I have had to pull the tank off and empty it. Then back blast the mesh filter ( fixed type) with a compressor and the muck that comes out . Beautiful! This engine especially your model is the best. Excellent video! Cheers from Australia just subbed.nice work 🙂👍👍👍
I think mine might be a fuel problem (mower 13 months old and barley used in relative terms). I will be following the draining / refilling fuel steps tomorrow and hope that sorts it. Many thanks.
Thanks! Love to learn tips like these😊
Great video. Many thanks
Thanks boss. Your video just saved me a trip to the mower repair shop

Thank you. I really appreciate your nice comment and valued feedback. Craig 👍
Good information . I like channel.. I like Small engine rebuild, therefore i won't hesitate watching your UA-cam channel.Thanks alot all TRS guys.
Best video I have seen it’s spot on
This fixed my issue thanks
perfect advice ....thank you
I have been in some form of horticulture for fifty years now so my experience looking after an estate with assorted engines has lead me to a couple of conclusions that work for me. I never overwinter engines with fuel in them except the real large tractor engines. I remove the fuel and make sure I have a clean tank, sediment is a bad carb and fuel filter killer. Run the engines until they quit so carb is also dry. First fuel of the season is premium ( no ethanol ) I only use premium fuel in my 2 stroke mix in my stihl engines. Ethanol based fuels burn too hot on the smaller engines. I also remove all fuel from containers putting last litre in a glass container for inspection.Its scary what you may find in the bottom of containers. I find these precautions can save you a lot of headache at the begining of season.Machinery is also compleatly serviced in the winter. Just my thoughts which have stopped me cursing so much. :D
that was very helpful. thanks
This was a very helpful video. However for complete dumbos like me it would have helped if it also showed how to remove the fuel pipe in a bit more detail. I had to look at another video for that
Thank you for your easy to understand directions! I'm hoping to start up my smaller push mower this season. I bought it used, and it never worked quite right. I haven't used it in years, and I'm sure that there is no gas left in it.
Good luck and thank you for your nice feedback. Craig 👍
But I'll wager the tank and carb are gummed up with gunge and grot.
Follow the man's advice.
The reason mowers don't start in the spring (as well as motorcycles, chainsaws and weed trimmer) is mainly because the gas has turned to varnish over the winter and clogged the carb journals and jets. Adding Seafoam in the fall will eliminate the problem and the engines will start up no problem. I've been using it for 20+ years and never have to work on my carburators anymore. (use it on your snowblower in the spring also!)
Never heard of seafoam. Is it sold in the US? Is it kinda like Stabilizer??
Seafoam is used for a stablizer and to clean your carb as well as adding it to your gas to keep your carb clean.
Seafoam is petroleum distillates
Good for cleaning fuel systems
But
Not a mechanic in a bottle
Best to drain fuel and run carb dry for off-season storage
@@philherrick7319 Ihave never drained a carb bowl for winter storage on any gas engine I've owned (I'm 69 years old) but I read about it being done alot. SInce I started using Seafoam many many yeas ago, I never had a problem with the engine starting in the spring. Just saying.
And for problem solving when I first start working on an engine, I first run Seafoam thru it to help clean the system first, which 50% of the time actually works to get it running. Then I continue to clean and adjust. No Seafoamis not a "Mechanic in a can" but it is just a short cut to getting an engine running faster.
@@PainterD54
You have had good success.
I stand by my comment (s)
Where I live we have ethanol added to the gas at the pump.
Ethanol is hygroscopic. BAD for carburetors/fuel systems.
At the shop I work in we do hundreds of mowers/blowers, depending on the season. The majority of the work we do is fuel related. It's not only a question of using a product to stabilize fuel. It's also a question of cleaning the problems caused by the water in the ethanol fuel, along with unstabilized gas. It's BEST to drain the fuel and run the carb dry.
That doesn't mean it always happens, however.
Thank you!
Great video with easy to follow instructions....thanks. Helped me alot.
Interesting topic, should also replace or clean the air filter. For me using fresh gasoline, cleaned carburetor I still need to use starting ether to get the motor running. Spray ether at the air filter, pull the cord, it runs well after the initial pull. I have changed the plug with no difference in a cold start pull. I also find adding isopropyl alcohol to the fuel tank smooths performance maybe indicating the ethanol in gasoline is absorbing moisture from the air new or old. Fuel stabilizer has not been a significant impact positive or negative but Isopropyl alcohol, aka gasoline antifreeze,5 has better results. In North America the red bottle of gasoline antifreeze at the store.
Great content! I liked and subscribed and will be watching more content!
Based on the thumbnail, id say try planting both feet on the ground first. You can't get a good pull while hovering in the air.
Thanks for your video so easy to understand and very well done. I subscribe and will watch your videos you are a good man👍🙏🏻
Just saved a trip to the rapair shop. Thanks!
Excellent! 👍
i had a lawn mower that ran great for 10 years and i thought maybe water got into the gas tank and i messed up the lawnmower engine, but thank you for your video i think causes explaind in your video is the culprit, dirt inside the gas tank, contamination, or a bad diaphram !!!!!!! thank you Again !!!!😁😁😁😁😁😁

Great stuff.
Thanks ! Fixed the mower ! But can't afford the gas now cost $7.00 a gallon !!!!!!! 😕
So did everything but changed that gasket now it will start like it's new thanks again
Awseome 👍
Fuel or spark were what we were taught at TAFE. So my mower ran first pull for years. Replaced the plug and pull starter rope as that snapped, went first pull again, I was so happy. Now it wasn’t start at all…….cleaned up plug, no spark, every elst is fine, so I’m thinking it’s the carby or the ignition coil
This was a very thorough and useful step by step ‘how to’ video. I’ve just watched your video and subscribed. Really well presented and well filmed video. Thank you for taking the time to put this up. It’s really useful to amateurs like me.

I have a sovereign xsz40 149cc when it runs it hunts now and again. Checked the primer bulb all ok. Cleaned the carb and put it in a sonic bath and removed and cleaned jets. But will always leak fuel out of the primer bulb.
YOU ARE A FOOOOOKING LEGEND!!! THANK YOU
Just watched this video very very good just wondered though my lawnmower has same problems and it's model number is Mountfield 100cc SP414 is that applicable to your video ??
Nice videos...I pull my mower out today and it wouldn't start...I change the spark plug n put some fresh gas n let it sit there for 20 minutes n it started..
Excellent video!!!
Thank you very much!
Always clean the high-speed and low-speed Jets, most of the time with ethanol they're plugged up I've rebuilt shitloads of these small carburetors
BEST VIDEO I have seen on Lawn mower repairs!!!!!! Thanks!!!!!
Wow, thanks! 👍👍👍
A wife in East Texas. Husband goes on an errand with son. I decide to mow the yard. Nope. Mower won't crank. Son-in-law, and son have smart cracks when I message to ask for advice. Hmmm ...I'll show them! I get on UA-cam, find this video. Drain gas tank and carburetor. Yes sir! About a cup of water. Gassed 'er back up. I knew I'd pulled on that rope a good bit before so I figured it would be a bit before she'd crank. Two pulls! She died a few more times while she got rid of the rest of the moisture but I had just finished mowing when husband pulled in. 😁 ....by the way, the smarty pants son was with husband when I asked for help. Husband was kind of surprised to see the grass cut. 😉 Thank ye, sir, for this well done and easy to follow video! Blessings to you!
p.s. I've parked the lawn mower UNDER a shed, out of possible rain. Husband parked it BESIDE shed in possible rain. 🤨
Absolutely awesome of you. Well done. Keep up the good work, and thank you for your brilliant comment and feedback. Craig👍👍👍
Nice on! 😂👍👍
Hey Craig, Pat here from Toronto. Just watched this for the first time and it all makes sense. My question is, should I empty the lawnmower of gas and run it till it quits before storing it for winter…..or…fill with gas and add some stabilizer???
Hi Pat. Either is good as long as you do one of them in my opinion. It will be good for the carb to clear it out of gas and introduce fresh into it as well though anyway. Thanks. Craig
Very helpful 🎉
Thank you
Cool video thank you
Thank you 👍
You know I looked at how long this was and I. Said this is gonna blow and I read it anyways and you know what I couldn't have been more right? And for this you won't be the last three minutes back of my life
ok
Thanks.
some people use the anti fouling stuff you can buy at walmart. they say you pour measured amounts into the gas tank. but i just clean the plug and it works for me. after about 10 cleanings of the plug, i just go buy a new plug and continue mowing.
great info u got my sub
New mower last year. Failed to start in early spring this year. Checked the oil, air filter and spark plug, still no joy. Decided to drain the tank and carb bowl. Fresh fuel, started first time! The old fuel had stabilizer in it, which I was under the belief would help preserve the fuel over winter, but not the case. I'll drain the system and run it dry at the end of the year.
I'm really pleased you found the problem, Its crazy how fuel can go bad and how its overlooked.
-Thanks Craig
Probably has to do with mowers having vented gas caps, not completely sealed off. And the carb isn't sealed off and vents.
@@timb7775 Yes, most likely. I read that lead free fuel lasts fairly well in a car tank, but not so much in a lawnmower (evaporation of some volatile compounds needed for good combustion). Exact same thing happened again this year; had to drain the mower and add fresh fuel; works fine now. I read that draining the mower tank and carb before winter might not be such a good idea, due to potential drying out/distortion of carb diaphragm/seals.
Thank you for the video. What can I do/check if after cleaning and rebuilding the carburetor, replacing the spark plug, fresh gas and my lawn mower still doesn’t start up?
Battery lawnmower
No fluff. Great Video.
Thank you 👍
Well done
Thank you 👍
I park my 20 year old mower in the garage over winter and it never fails to start by 3rd pull using the fuel from the previous season. Mind you, I do maintain it well... one oil change and one new plug in 20 years of use.
Have a lawnmower from the 1980s,I've never done anything to it in 25 years except add oil. Thing always starts in a couple of pulls. Even using 3 year old gas in it.
My 4 year old lawnmower made mostly plastic gives me nothing but grief,no matter what I do 😆
Not had a fuel problem yet but I have poor starting due to blowing head gasket and another time dirty oil (must get past rings). No starting down to coil or HT lead failure. Erratic tickover caused by broken governor.
