"At this point, you're frustrated and ready to take a hammer to it!" Thanks to this video, I am no longer at that point 🎉 - Wathing from Virginia
Nice!!
I think any of us that cut grass regularly all have the same conversations with our mowers. Famous lawnmower words spoken the most to them are “Come on, come on, come on!!!” and “Come on, baby, start!!!”. LOL
Your video is the best angle filmed, fast and to the point. I’m a Daddy’s girl that was taught how to fix a lot of car stuff (back in the day when you could actually get to a car’s components and repair them yourself) but never helped Dad with lawnmower repair. Midway cutting Mom’s grass last week, mine just stopped on a dime.
I ordered a new filter, filter cover and plug in a kit. Truth be told……also ordered a new shut off/throttle cable because that one broke 3 weeks ago and I had to take the one off the Craftsman mower. It was a bit longer but has worked fine. I prefer my Yard Machine. It’s lighter to push and can get up to edges more closely, less need for trimming.
Gotta hand it you…ingenuity at it’s best👍👍😊
How did this guy see right into my soul and know exactly what my situation was? “If you’re a guy with a six pack in his fridge, couple pairs of pliers and some small tools…” 😂
If it delays the beer…it better be more serious than a spark plug😂🍻
Watching from Saint Louis Mo
Thank you for the video. Very informative
I got a good laugh out of the slight burn lol I do it all the time
Nice! My Daughter lives there!
Mower died out a week ago when I was cutting. Toro recycler, It had too much oil and the plug was fried. New plug and correct oil level and new filter, started fist pull and ran like a dream. Thanks man🤝
I thought my carburetor needed cleaning. Checked the spark plug first though and sure enough, a new plug makes all the difference. Saved me the headache of doing the carb. Running like new again.
Absolutely loved the video. All points hit dead on the head and entertaining. Hilarious. That was me. Gone to cut the grass. 😂
Word!
After watching last week's video, checking the spark plug FIRST, is ingrained in my brain!
I love small engine repairs,found a thrown away mower that looked recently new like a year or so and went to diagnose it and checked the spark plug and it had oil and water on it so i cleaned it up checked carburetor and cleaned that as well and pulled the cord...and started up but spark plug was in need of change so got a new one and runs like its brand new.
First comment 👋🙂👍👍👍👍
Thank you for the advice because I did the same thing because my mower stopped and started for a little and died so I tore it apart and it never worked again
Thank you so much! Water issue for me!!
Great!!
I watched to see how you removed the spark plug!! Teach more than you know, sometimes.😊
Word!
Straight to the Point. Thanks a lot. Helped a ton.
champion, thanks for the advice, picking one up in the morning. cheers
You saved my day, another tip don’t use champion spark plug, NGK is the best
Yea!!
Thank you. My lawn mower want run. I put in a new air filter. I primed it. It seemed like it wanted to start. I will check the spark plug
Thank you for this video!
Thank you from Florida👍
Nice!!
I find that when they have been burning oil they are more likely to foul the spark plug,my 32 year old 3 horsepower Briggs & Stratton powered lawnmower still runs the original spark plug,it has been oil fouled before but not shorted out (it still ran),I've since replaced the piston rings & now it has a nice grey colour after I have cleaned the spark plug used the mower for a while rather than having dried up blobs of oil on the electrodes !
WOW!
In your last video on the murrey you tested to see if it had spark and it did but I saw it right away, it was sparking back into the porcelain (fooled) I I cant tell how frustrated I was watching you struggle through that knowing all you had to do was replace the spark plug, go back and watch that video Nathan and you will see what I mean. It wasent sparking across it was sparking back into the porcelain, anyway thanks for explaining to those who might not know , CHANGE the spark plug first (there cheap)
Awesome I kinda figure appreciate it coming from you it helps when two minds are on the same page.
Nice man!
Thanks I’m giving it a try

Thanks great information****Incredible video! ****with some good knowledge shared. ***Thanks to this video I finally tossed an old bad batch of sparkplugs I'd been keeping. Just because they deliver spark on a tester doesn't mean they are good. Once the spark plug is in the ignition chamber and heats up, the internal resistor begins to fail due to heat and is unable to conduct electricity, resulting in the spark being gone.
I noticed this anomaly as a fairly *clean** spark plug delivered spark when the engine was cool but would not start when the sparkplug was hot. I swapped out this bad used batch of old plugs and wondered why they only ran cold and would not run again after the mower warmed up, answer: because they were bad!
Great knowledge, you 👏 earned s subscriber.
If it starts and runs but keeps popping it is likely to be the spark plug too. Popping is caused by misfire.
Man I wish you had made this video alonggggg time ago, lol! Guilty of this myself!
Watching from the home town of the late great Buck Owen's!
I know that place!
I was stationed at Ft. Irwin CA for a few years. Me & some buddies made the trek to see him perform at the Crystal Palace. I'm glad we did, as he passed a few months after we went to the show!
I'm going to try this. Thanks!
Ok.
Something else to take into consideration. Make sure you use the spark plug that the engine calls for as non resistor type plugs can cause interference with the ignition system on these and many other small engines.
Thank you . you saved me a lot of money.
Nice!
You are a money saver i was about to get a brand new mower
Nice!!
Last year I was trying to get my old Briggs & Stratton mower to work, it's 23yr old. After changing gaskets on carburetor and swapping out the old foul oil, it ran straight away.
I pulled it out this year and it turned over straight away, I let it run for a minute, thought great, it'll b good to go for morning for lawns.
This morning... it would not start, well it did for a few seconds and then died. Changed the petrol as it does go foul but no joy, turns out I'm having exact same symptoms as you, it's the spark plug.
Anyway, thanks from UK.
Nice!
Hello thanks for the video, what size is the Deep Socket I can not find one for my Sears /Craftsman shredder...
i was so mad bc my mower wont start. after abput 30 minutes of cursing I check the gas tank..yep. LOL
O man!!
watching from scotland
I used factory spark plug until i stripped out the head and found Bosch spark plug it runs better but it keep running. After i change the head it keep backfire so i adjust the valve with a friend he help me out it back fire once in a while i only use e0 tried e10 but carb gets clogged so i used e0 and it is 2017 murray 4.50 ft lbs 21in.
Thank u
Word!
Great video ! I have a sparkplug brand new and it won't start my lawnmower. Talking about a hammer 🤔 Sounds good 😢
hello Nathan and thank you for this helpfull video
i ve suscribed of course
i have one question u may want to answer when u get spare time
i will try to explain despite a bad english lvl
i sold a lawnmower last day and the buyer also brought me his old one (not too old tho 7-8 y old) and asked me to have a look at it
a friend of him tried to repair it but replaced the spark with another one, more powerfull , telling him, it was better for the engine
after 2 successful tries, the lawnmower engine stopped working
what if i check the engine specs on briggs site and start by replacing the plug by the recommanded one ?
might be the more logical first thing to do you think ?
sry i hope you get the point
thank you
I'm
watching from Spanaway Washington
❤thank you for this video!!! ❤
A bad plug is probably the most common cause of a small, air cooled engine on a lawnmower, chainsaw, or generator, not starting. The other one is old gasoline, which has had the lighter components of the gasoline, which are the most flammable parts of the gasoline, evaporate away during storage. That leaves the gas tank filled with an oily liquid which no spark will ignite. They say the old gasoline has, 'lost its lights'.
In very humid climates, the alcohol in most gasoline today will draw enough moisture out of the air to eventually cause a layer of brown liquid goo to form at the bottom of any gas tank which is vented to the atmosphere at zero pressure, like many small engines usually are. Every few years, I had to get a plastic tube and suck it out of my lawn tractor tank, before it could build up enough in there, to work its way into the carburetor. Now I use ethanol free gas from a local Chevron station. That solved the water accumulation problem. Since I don't drive much, I use it in the old Ford Expedition too. Better to spend a few more bucks on fuel, than get rust inside some expensive fuel injectors.
After viewing your video, I'm left with the impression to go ahead and purchase a new plug and try it. So now I've driven to the store and spent the money. BUT what if it wasn't the plug, it was just "old" gasoline in the tank. Thought I was going to see how you actually TEST a spark plug before buying a replacement. All in all, informative.
Old gasoline will run. Trust me.
Honestly I always try new fuel I've picked up plenty of curb mowers that just needed new gas and ran but ik if fuel wets the plug they act like this also Im testing E3 plugs right now so far there impressive
Great Idea!
There is a reason why I order spark plugs in 10 packs for my small engine business.😉 Nothing worse than needing a spark plug and not having one. It's a good idea to have a spare brand new plug on hand for your mower. And don't forget to gap it. Smaller gaps are better around .025" is good for most mowers, especially Honda.
And stay away from those generic plugs
@@unclejoe6811 I use NGK for almost everything now. I do stock some Oregon plugs for suspect machines that might not be worth the NGK and I have had zero issues with them as well as the NGK.
@@patthesoundguy My issue is locating (and being sure I'm buying the right plug. I have an older Kohler Magnum 8 on a mortar mixer. Would you happen to know what NGK plig that would call for?
@@finders-keepers1518 I found the manual for that engine and it calls for a Champion RCJ8. The cross reference seems to be an NGK BMPR6Y or 6A. Which equates to Thead diameter of 14mm, thread reach of 9.5mm (which is very important as to not have a piston or valve smash the plug) and a non protruding electrode. I really think if you can't find that particular plug you would probably be fine with a BR2LM which is the Champion RJ19 mostly the same specs just a bit hotter plug and protruding electrode but same reach and diameter and more readily available. It's a bit taller plug so that could be something that may be an issue or not depending on the wire length. There is also a good chance the RCJ8 is easy to find.
@@patthesoundguy Thank you a ton!
Do yourself a favour and purchase a volt/ohm meter and an ultrasonic cleaner if you do alot of mower carb. and ignition work. The meter will measure the resistance of the plug. The cleaner will super clean the plug deep to the bottom of the insulator and clean the carb parts to a pristine state.
@Hank Bridges Ohm meter will also check resistance. If plug is within spec., then the problem may be elsewhere. Thanks for your input. Best to you and yours.
mwhat about when it comes to gapping the plug? does it matter or what's the correct gap for push mower?
within reason .000's
The six pack of beer in the fridge won't be Bud Light.
Nathan...you should do a video on the quality of small engine carburetors sold on Amazon. Briggs is expensive, some are a little less and most are super cheap...but are the cheap ones any good? I'm currently shopping right now and see brands Butom, Liyyo, Yermax, Hooai, All-Carb, Carbhub, SYL, Mdairc, Nimtek, Atvatp, Mengxiang.
Good Idea.
Nathan Rohrbough nobodies done that video yet. Feel free to delete this comment after you read it. A video like that is worth a lot of views.
Inspecting the plug you can see if it has problems!!!!!!!!! You need to see pictures to compare a good plug and how to tell other problems with the engine!!!!!
Thankyou, I'd love to know what's actually wring with the plug, if it has spark why is it not running? Does it have a hairline crack or something?
Yes, a faulty area that still makes contact...generally when cold. When warm the "crack" opens. Many plugs also have resistors inside for the current to go through. They burn out, sometimes a bit at a time. Personally I try to avoid resister plugs for my equipment. Easier to test a non resister plug with an ohm meter, though you can still test the plug if you know what the resister value is meant to be.
A coil can also give you similar symptoms. If there is a break in a coil wire, it can connect when cold, but opens up when warm.
i change mine every season, they are cheap, and sometimes the old one won't fire under compression.
It’s a good idea to change the plug every season,but, that’s not necessary , my 2007 MTD Honda lawnmower still have the original plug in it, only removed twice to clean it up for all these years, always start up in first pull.
but I have quite a bit of some The problem on the wheels ,and most of the transmission .
@markhan I changed mine often when I was younger until I bought a defective new one. That's when I figured it was time for me to learn a more definitive way of diagnosing a plug's condition and when it should be changed. Presently, most of my equipment have their original plugs; some pieces are over 40 yrs old.. As long as it starts promptly and runs well I see no need to replace the plug.
Water in the gas tank, the mower's and a portable fuel container, is a feature of ethanol. I always check my fuel container before filling my equipment. The days of having a store of gas for emergencies is over; today's eco friendlier gas doesn't store well. You erred somewhat in your supposition of at what point in the analysis process someone would suspect the carb.
Yea true!! You rock!!
What spark plug did you get? Size and Type. Similar lawn mower. Just trying to get itbright first try.
My question also size,type, ect
I buy spark plugs in shop packs. First sign of trouble, I just switch out the plug.
Gave a friends mower a tune up air filter oil change and spark plug. The plug was a champion like the oem plug. He called me the next day he would shut it off to empty the bag and it would not start would let it sit 30 min then it would start.He ran this thing before the tune up no problems. I still had his old plug went to his place ready to drop the carb bowel but instead put his old plug in ran the mower for 15 min way more than it would take to fill the bag.let it sit 5 min started right up. He is still running that plug 3 years later not going to replace it untill there is a problem. Pretty bad trying to prevent a problem causing one with a new substandard part there goes preventive maintenance out the window.
Check him out learned from last mistake tearing it out and then found thw spark plug was a reason. Then bam he makes this video to just have a video so his money maker keep going. I sure hope every man knows to check their spark plug. Hopefully every man knows to check their spark plugs. I called spark plug moment it wasn't the carburetor on the last mower. And im no small engine mechanic. Great vids on common sense stuff
Man, with all the negative issues of spark plugs and gasoline, I'm just gonna swap out my spark plug for a bolt, fill up the gas tank with diesel and go from there!
I bet it woulda started if u pulled on the string harder lol
Nope all ready tried that!
My was making a loud noise like fire cracker and a little fire comes out
Pop, pop!!
Oh! Is how that you called it. 😄
What if the same engine starts smoking and run poorly?
Too much oil? Check the oil level.
Could be flooding itself, too. Check out carb.
most of the time it isnt the spark plug...but sometimes it is.
HopefullyNo BUD LIGHT in fridge!!
I will NEVER buy it again. Stupid commercial.
The title of the video should be "when Briggs & Stratton made engines to last" I have the same model mower👍👍
Word!~
I had that happen once, I installed an in-line spark tester, and it would run fine, but with just the failed plug, it would run for 20-30 seconds then die. Of course I figured this out after taking the carb off and cleaning it, which didn't fix it.
You barely put any torque on the sparkplug. I had a mower that surged because the plug wasn't tight enough. 15ft lbs.
he did
@@markrush5013 actually he didn't. look at 2:50
Ok
.. .
My b. Me
Ok me 3 also.
Don't buy any plugs on Amazon as it is flooded with counterfeit plugs as well as everything else. Buy from a reputal store or dealership. The mechanic shops and dealers are seeing a lot these inferior fakes.
I have hard Murray mowers are crap so never purchase one.
why are you wasting time replacing and starting with a plug you know is good?!?!?!
Its kinkled in place.
