The Spark Plug Gap Is NOT Critical (With SHOCKING Proof)
Vložit
- čas přidán 26. 05. 2022
- Lawn mower won't start? Are you told your spark plug gap is the problem? I'm experimenting with wildly wrong spark plug gaps to see if they work. Testing plugs that are WAY out of spec, both too big and too small! I think the results will "SHOCK" you, LOL....

@Steve Greetings again from Marine City Michigan. And once again absolutely love your channel. Would love to some brewskis with ya!!!!! "D"
agree. i have always used a beer can tab. never failed.
@@ramonazteca252 You get it! Thats all Steve was trying to say and it flew over many peoples heads. He only said if it doesn't start, don't spend the day trying to set the plug gap because its probably something else. Then these jackasses are on here talking about multi cylinder race engines with fuel mileage and horsepower ratings. Unbelievable...
It's true that a wider gap will also work especially if the engine gives a good strong spark but the larger plasma arch will eat away at the electrodes much quicker . The spark gap is a compromise between the two . That's what I learnt in my motorcycle racing days . If the gap is too small small pieces of vaporized metal and carbon will build between the gap and eventually short it .
Good stuff thanks for extra info friend
@@pabloramos2658 De nada amigo .
Exacta Mundo!
I raced too and found the same.
That makes more sense to me!!
I am always amazed at how many people talk about changing their sparkplugs every year or even less.
My 2011 ford Ranger with 32000 miles on it has a replacement recommendation of 105000 miles.
I am however happy that they support our sparkplug manufacturers and keep them in business.
If the gap is too tight the plugs can foul easily and you can have no spark until they are cleaned. Too wide and it may not work with a weak coil. It's not critical but it's best to have them gapped at 25 to 30 thou or what the maker says.
It's good to know that the gap isn't that critical! The specs sure are splitting hairs usually. But.
Now I want to see Project Farm test a variety of different gaps for fuel efficiency, torque and how they perform after a longer duration and get sooty :-)
Yes, that would an interesting test.
I would absolutely like to see a vid on this.
Gaps are more important on multi cylinder engines where misfiring can occur. Single cylinders don’t care as much but may lose power and efficiency if too small or large a gap. Cool vid Steve!
I agree with 100% Kenny!
Yep with multiple cylinder, gap is wayyy more important... Rock on kenny!!
@@StevesSmallEngineSaloon me too!
@@StevesSmallEngineSaloon So According to Ken thier , the whole thing was just a stunt , Looks like the May 2- 4 weekend was one day too long for you
I agree especially on older style ignition systems because there are many more gaps than just the spark plug ei: points gap, distributor to distributor rotor gap, spark plug gap then factor in all the places that you can have a bad connection coil to coil wire, coil wire to distributor, distributor wire to spark plug wire. These all add up and if there is too much gap the ignition system cannot overcome all of them then you have driveability issues.
I would like to see these tested under a load (i.e. some tall grass) to see if there are performance issues with either one. I may try this experiment too.
Would love to know your findings
..Still waiting for the tested vid under load! I will watch and like.
Still waiting under load😢
Yep!underload will tell all,please be 100percent thorough..no power at those Xtreme gaps and probably higher fuel consumption
As a kid, we used to mix gas with used engine oil to run our two-stroke dirt bikes and go cart. Used to have to check the plugs often. LOL. I think knee-jerk check the plug comes from the early two strokes fouling plugs.
You are definately a cool mechanic. I've always been of the same mind. If a spark plug has a gap it's close enough. I run Fram filters in my truck too..No problem in over 50 years. Thanks Steve!
Right on
Fram for 40 years for me in NZ with no issues either
Fram filters are the worst out there according to extensive testing,napa gold was rated one of the highest if not the highest,fram least amount of paper filtering element,bottom of the barrel
If everything else is right, then the plug gap is just a suggestion. However, a weak coil will rear its ugly head if the gap is too much. Likewise, if the motor is using oil, a small gap will foul more easily. I have some old outboards dating from the 1920's through the 1950's. The factory spec on oil ratio is 1/2 pint of oil per gallon of gas. One goes so far as to require 1 full pintg per gallon-yes, an 8 to 1 ratio. Somehow, I don't think these motors would run very long with
plugs gapped at .010
Glad you made this video I thought about it but I was afraid people would call me out
Amazing you still generate content Steve. We appreciate you out there!!
Thank You...
Steve you're the spark that ignites all these vids.
Thank You...
Good video Steve! I agree with your points. I have never seen anyone start or experienced myself starting a neglected engine and worried about the spark gap, short of extreme fouling or damage. If it sparks it will ignite!
Thank You...
Good one Steve. I would not have known that until you showed us. I never really worried about having gap perfect. I just usually guess at it I basically make sure gap is reasonable. Just like when I sharpen a blade I never worry to much about the balance. I hang it on nail and if it's fairly level I go with it.
Nice to see you back on CZcams Steve.
thank you for your help
Your standing there of course it's gonna stay running. Try putting under load and cut thick grass.
The whole video is about will it start or not!
@@StevesSmallEngineSaloon If your standard for whether or not spark plug gap matters is simply whether an engine will start and run under no load, I think you're a tad goofy.
Last month I was mowing with my briggs and I shut it off halfway through the job to get myself a drink. It was off maybe 3 minutes tops. I damn near wore myself out pull starting it, when the damn thing never fails to start on the first pull. Pulled the spark plug and held it against the block while I turned the engine over to check for spark - none. Pulled the grounding wire off the coil to make sure it was not the issue - still no spark. I was ready to order a new coil when I decided to inspect the spark plug electrode with a magnifying glass. There was an ultra thin particle bridging the gap. I have no idea where it came from, or what it was made of, but assumed it was causing a short. I verified it was shorted with my multimeter. I used a razor blade to remove the particle, reinstalled the plug and she fired up on the first pull, as it always has. I had witnessed this phenomenon twice now, the first time a few years back with my string trimmer.
There is some carbon that forms in the top of the cylinder (the head) - you see it if you pull the head. Once in a while the running of the engine might break off a flake of that carbon and, instead of just going out with the exhaust, it lodges itself across the spark plug gap.
Carbon conducts electricity and effectively shorts the spark jumping across the gap. - Joe -
@@joesinakandid528 Never thought about that, it makes perfect sense. Those things literally arc weld themselves in place, and seemed unusually tough to break, despite their tiny size. Maybe they're carbon nanotubes! Thanks, Joe!
That shit-eatin' grin at 1:10 says it all!
Thank you Steve, really appreciate the information on spark plugs. Great videos that are helpful.
Glad you like them!
If only I had a dollar for every customer that said it only needs a spark plug

Good video. However, I've been pulling, cleaning, and re-gapping my plugs for nearly 50 years without a problem, so I think I'll continue. In doing so, my plugs seem to last about 25 years.
Spark plugs usually last a long time. People throw away perfectly good plugs, and put in new ones all the time.
@@mikespain8655 I'll posit that replacing a spark plug for only a few dollars is well worth it to eliminate the possibility that there are minor issues with the plug that sap performance and increase emissions. A thermal stress crack in the porcelain, conductor, and/or suppression resistor can form from the extreme thermal cycling that a plug sees. It's possible that there's a well-formed tracking pathway or a few small pathways that developed over time which can't be fixed and will always partially (sometimes completely) divert electrical energy away from the electrodes. That reason also justifies regular replacement of spark plug wires or coil pack boots because tracking burns/melts them and the track can never be fixed. It's possible that there's internal corrosion which increases the resistance of the plug's guts themselves. It's quite often that a plug has a ring of rust around the place where the porcelain meets the metal body. As the plug wears, all of the sharp corona discharge points wear away because the spark jumps from the highest and closest one first until that place has been vaporized, and it carries on until the surfaces of both electrodes are rounded and polished smooth. This is undesirable because the spark forms easiest and it is most efficient maintaining the ionized arc when those sharp corona points are present and utilized. That is why platinum and iridium plugs have a very tiny, sharp needle point for both electrodes as well as using the very arc erosion resistant platinum and iridium metals. Those plugs maintain a pointy, hard tip/edge which presents a fantastic corona breakout point for the spark to jump across and stay concentrated and very hot during the full duration of the coil's magnetic field collapse. In a combustion chamber at TDC compression, the air is much more dense than air at atmospheric pressure and it's more difficult to form a spark. You can actually see this by using a scope to plot the primary and secondary waveforms. The strike voltage peak will be higher. Having that sharp corona breakout electrode is much better than a rounded arc-polished electrode surface even if the latter is gapped correctly again. A poor electrode form will cause spark to be delayed in timing and it'll be wimpy, which affects power and emissions. Most new cars today are equipped with iridium or platinum plugs, and they are long service life plugs due to their wear resistance. My Toyota for example, calls for NGK Laser Iridium plugs at a 120k mile lifetime. I changed them at 60k. Why? The 4 of them were $40 from the dealer and I always do perpetual maintenance that preserves the efficiency of combustion as well as reducing the amount of engine oil burned in order to prolong the life of the catalytic converter which is a big expense that plagues older cars. The dreaded P0420. 🙀 $40 in nice new plugs was worth it to make sure the fuel:air charge is ignited as best as possible just like when the engine was brand new. This also involves MAF sensor cleaning, throttle body cleaning, fuel injector cleaning or replacement, AFR and O2 sensor replacement, thermostat replacement, and the use of quality gasoline. Most of that doesn't apply to a lawn mower engine of course. In fact, most of this won't apply to a flathead mower engine except when tracking or corrosion gets really bad and causes misfires, or decreases power and fuel economy enough to be noticeable. I just want to offer up reasons why "good" plugs being thrown away aren't always "good" despite appearing to be in one piece, and that being penny wise but pound foolish is not a very good strategy when maintaining a piece of very expensive machinery.
@@mannys9130 Dayum. You got a publisher for that book? Lol. Jk
Most people are very quick to change the spark plug if the machine is even slightly difficult to start. The problem is more likely to be caused by something else such as stale gas, or a blocked spark arrester. A genuinely bad spark plug is rarely if ever the problem. If the plug is sooty, it's easy to clean. I find spark plugs don't often need replacing and last for years.
I can't really see the point of the video, as it's so easy to set the correct gap with a feeler gauge or an accurately measured piece of card, and having a gap which is much too small or too big is asking for problems somewhere along the line.
@@mannys9130 That's pretty interesting stuff, but pretty useless in a real life troubleshooting. I just ground the plug against the engine and crank. If I see spark it's fine. Personally I think It's a waste to replace something that works fine. If it's working it ain't broke. Guess that's what comes from me being a country guy, on the farm you just gotta simply make things go XD
Great advice
I agree it's not that crucial. Only in a few cases have I seen it matter some. Like in the 1986 Chevy Celebrity I used to have that had early fuel injection on a four cylinder, it called for .060 gap and I was told by someone in the know that the larger gap for for the leaner mixture and he told me that an .030 gap would mean horrible misfires. Also when I was into 2 stroke Honda scooters we found through experience that the Honda spree liked an .025 gap over the .028 or larger. Those things only liked the stock NGK BPR6HS plugs as well, they were very finicky that way. Other than that most stuff doesn't care, just like you showed. I had a late 70s 5 HP Briggs on a rear engine rider that the gap was almost closed and the plug was loose and the thing still mowed 6 foot tall grass with no issues.
Thanks for the info!
Any time!
Thanks Steve. I knew it wasn't critical but I had no idea you could open it that much. I have closed them tight though but that is a story in itself!!
Glad to help
Retired automotive instructor.... like he mentioned it can lead to damaged components. Electricity will take the path of least resistance... the ignition module and coil will increase spark output in order to jump a wide gap... this can lead to premature ignition coil damage however if you have a bad connection or damaged plug wire insulation most ofter it will cause the spark to jump to ground before it reaches the spark plug... you can also read the increased kv voltage on an oscilloscope.. if an engine is burning a little oil you can open the plug gap up which will increase spark voltage and may help keep the plug from oil fouling... only recommend on an old worn engine....
Saw this video and needed to so some weed whacking. It was sputtering a tad and not the same power I was accustom to. Boom what a difference a fresh plug makes on an old machine. Once again I have followed the same over wintering routines that Steve has recommended over the years. Mainly storing with fresh gas and starting at least once a month. Cold damp spring in Oregon this year, yet the yard equip. still humming along. Thanks Steve, my stuff is old from the early 2000's, still doing the job.
LOL your stuff is old....early 2000's. I am running mostly small engines from the early 1960's. I do have some new stuff though. Generator, snowblower, and cheap line trimmer is newish. My Yard Machines line trimmer is crap, I should never have even consider buying this. Thought the price was right for a straight shaft trimmer with clutch. Fixed up a friends trimmer the other day, smallest of Stihl curved shaft trimmers, and very hard used. WAY better, way more power, way less pulling binding grass out of the cracks; and I now see the price is about the same as what I paid for what appeared to be a higher end type machine. I don't think I can even replace the trimmer head with a better one. Damn thing is head on by a friction/jam washer. Some of the older stuff was made way better, but there is some decent manufactures of small engine equipment today too.... I will never buy anything from Yard Machines again though. My trimmer has only a few hours on it. Only changed the line once. I will junk this before spending any money fixing/replacing parts, and I can tell it will not last.
I have an old Homelite line trimmer someone gave me several years ago, that I haven't gotten around to rebuilding the carb, replacing the primer bulb and maybe the gas lines and filter as well. Now I am planning to get this running before my crap Yard Machines trimmer falls apart. I bet this old Homelite beats the pants off my new trimmer.
I had a 7 HP Briggs & Stratton . The gas was in over the winter . I flushed the tank , line , removed and cleaned the carb . I put in all new gas . I cleaned the plug, it was not wet with gas . No start . The gap was .025 . I regapped the plug to .030 . It started on the first pull .
Uh Huh
It was a coincidence.Truthfully, .005 of an inch will not create a spark/no spark scenario in a small engine. These are not alcohol burning multi-cylinder race engines. Thats what Steve was trying to say and many totally missed his point.
For whatever the reason , that was the last thing I did to get it to run . Again , the plug was not fouled or wet with gas . And I did give it about a dozen pulls with the plug out in case there was fuel in the cylinder .
So I was just talking about plugs today. I was trying to.find out why it is important to use the "correct" I normally just Find a new one that looks like it and I have not had a problom yet. What can happen not using what th we oem recommend? Thanks so much for your chanel. I have learned a ton from you and fix things I normally get for free. Im getting pretty confident in my work for the most part, and what to look for because of you
Extremely interesting. Thanks!
You're Welcome...
I'll keep that in mind.
It is funny how many commenters don't understand the spirit of this video. Really appreciate this and all your helpful videos!
I agree!
Maybe on a Honda gap doesn't matter.... But I bought a Toro early this season. Trouble with warm engine restart. Gap was almost nonexistent, regapped plug, runs like a jewel now. Took about 12 seconds to fix..... thanks for the video, but I'll keep checking plug gap anyways.
That was pretty funny. Anyone with a race car that has a big coil knows that the gap you started the 1/4 with was a LOT tighter than the one you brought back to the trailer.... with the car still running strong.
@@obamapox8185 it worked on my 340. Smokey yunick showed me that trick burned up my plug wires on the drive home though.
It does warm the wires a bit 😆
Nice one Steve, I did think the gap was important than what it is. 👍
Your right Steve, it's not the spark plug, it just needs a beer 😁
Thanks Steve.

Im in BC too (east kootenays) and finding a deceny small engine repair guy is a crap shoot.
Youve put me on the right path more than once.
Cheers, bud.
Thank You...
Great troubleshooting tip Steve
Thank You...
Small engines yes... EFI with a system that adjust fueling and timing based on gap, air etc Just replaced my plug in my truck. .040 gap is what it requires, it came out at 0.0625... lean popping and running hot. Not lean enough the melt a piston or burn a valve... thanks to the EFI and the O2 sensors which was reading "lean" and throwing fuel at it like bailing water out of a sinking ship. I'll let you know what the next full tank gives me for Milage increase from the 13mpg
When were using points in the 60's and 70's the gap on not only the plug but especially the points were critical.
Excellent. Now play with coil gap as I've found makes a huge difference.
Coil gap affects timing
@@KensSmallEngineRepair Coil gap does nothing, I have gapped engines coils and some I intentionally gapped wrong, It runs the same all round. I did this with Honda's, Briggs, Tecumseh, Onan, Robin, and many more, It does not matter.
@@AJRestoration so if I gapped a Briggs coil at say 60 thou (0.060) the timing wouldn’t be slightly retarded and result in a weaker spark?
@@AJRestoration
He is right that it will change the base ignition timing, however that wont stop the engine from running, it just wont have quite as much power.
The coil low tension is charged faster the smaller the gap, just as it charged faster as RPM rises which results spark timing advancing as RPM rises, it does that by design. When the module senses the coil is fully charged it opens the circuit and coil HT sparks.
So the smaller the air gap is the more advanced the base timing is. If you set it too wide it will just retard the ignition base timing a bit and so spark will be a bit late and thus you loose some power. Would it be enough to notice it ?, maybe not.
Wow thanks, I really thought it was critical to hit that gap pretty close. Now I know.
i gapped a weedwacker plug to spec and it felt ok but would just eat through a tank of gas then i tried a gap that you said then it seemed to have more power and it was more fuel efficient
I always get thirsty watching Steve
Steve you proved you point, now I had nothing better to do so I wanted to check my 2016 Accent`s spark plugs Believe or not I could not find it in the owner`s manual what should the gap be? what you think the gap was about .037" so I left the way it was.
Excellent video.. Thank you
Glad you liked it!
Great video Steve - and what a great Husqvarna mower- swedish power 💪 enjoy the weekend!
Thanks Andy!
Thank you!
Welcome!
I have a feeler gauge and the coin shaped gauge. So I have the right equipment. For the last 30 years I have used those tools AND I have on my Ski doos and wheelers and chainsaws and mowers and many outdoor pieces of equipment run into many many situations where i did not have access to those tools and gapped the plugs by eyeball and never had a problem. I bet its been ten years since i gap measured a plug. Long ago after "field" repairing some toy I never went back and remeasured because they have run fine! This seems to be a conspiracy by the gap tool makers to sell a pice of equipent that modern engines do not even care about any longer. One adjust ment to the next when I have gap tested them has never seemed to make any difference,
Thanks for confiriming my suspicions Steve! Good work.
Very informative channel, glad I found ya
Just replaced the exhaust lifter that was cracked on my gcv pressure washer 190 and now pull starts easy. My issue is it pulsating at idle and even though it seems to spray well it will backfire like once in a while. Do they pulsate at idle? I have noticed that at times it looses water pressure but my other one did too but as this one does if you let up on the trigger and press again and pressure comes back
Sorry for dragging this out, my main concern is the idle pulsating issue, thanks
Excellent troubleshooting tip 👍🏻🇺🇲
Thank You...
thanks again man!!

The same goes for points gap and the flywheel to coil gap.

I just installed a iridium denso plug in the riding lawnmower. I didn't gap it and it starts and runs perfectly fine.
A spark ís a spark,, cheers 😀
Nice video Steve 👍
Thanks 👍
Thanks Steve from Michael in Australia
You're Welcome...Mate!
I think years back with lower output ignition systems plug gap was much more important , I have seen engines refuse to fire with to wide a gap .but that's little Briggs made in the forties or fifties . To give Steve credit he did say Honda , and they have about the best small engine ignition on the market
Great info Steve. Now I feel justified for not worrying about my single cylinder engine spark plug's gap all these years.
What was today's brew?
Thank you, spark plugs sure have a mystery attached to them.. Also thank you for having no annoying back ground music, Cheers
You're Welcome.. .
thank you for the videos
You're Welcome...
I have this argument for years when people say your mower runs like crap because the plugs were not gap correctly
Drive my truck through it😂😂😂😂. Great shortie Steve.
Thanks 👍
And for 50 years I have painstakingly checked the specs for spark plug gap and set them accordingly. Thanks Steve for letting me know I’ve wasted quite a few hours of my life doing something unnecessarily👍🏻
I have always been told that if you got a misfire in an engine that a lot of times reducing the gap in an emergency if you have no other spark plug around usually fixes it and I’ve actually tried it once and it did work
Is the torque of 13 to 14 ft-lbs critical to place spark plug inside an engine?
Had carbon build up on my Toro sp and cleaned it by spraying with circuit cleaner. No scrubbing needed. Let air dry about one minute and screwed back in. Started on first pull.
this was a surprise. i dropped a plug not to long ago and
the gap closed to around 10 and i didnt notice. it made the engine hunt and after recleaning the carb and changing governor springs i said well that new plug must be bad and there it was almost tuching so i just pulled it apart so it looked good and it ran perfect.
JUST ONE WORD=EXCELLENT!
Thank You...
I don’t really ever replace spark plugs anymore. I clean them with my torch, then blow out all the burned up deposits and it works every time. I swear I had a briggs engine from the 1960’s and the plug was original. I heated that baby red hot and after it cooled the plug looked like brand new. No wear on the electrode, installed it and worked perfect.
You the man. Bud time.
Right on
That was surprising Steve!
Thanks for the proof of a mower NOT starting because of the gap.
You're Welcome...
GREAT VIDEO STEVE ,
Thanks 👍
@@StevesSmallEngineSaloon YOU'RE WELCOME MY BROTHER .
10/4 that's pretty cool.
Thank You...
I'm impressed Steve, but will at least still check the gap.. LOL
Please do!
Say ain't so, Steve 🙀
Love this 😎
Thanks Buddy!
I've never worried toomuch on my spark plug gap neither steve
I tore some plugs out of my subaru that were so worn there was barely anything left to it. Still ran, not great, but it ran. Didn't think twice about checking gap on the new plugs since I'd seen the 1/4 inch gap I was running on before
I agree!
A lot of spark plugs are pre-gapped. Copper ones need to be gapped, but the platinum and iridium sometimes come with a protective sleeve on them. It's used to ensure the gap remains consistent after it leaves the factory. Usually because, there is a puck of metal on the tip of the electrode. And improper gapping techniques can chip off the puck, compromising performance and life span of the plug.
love the videos
can you do a video on how to adjust the carburetor specifically on a sthil fs120
I haven't checked a spark plug gap in 25+ years. Lol
Just watched an excellent video on explaining the workings of the coil. Was a very in depth video showing why they fail, heat, insulation etc. It said having too big of a spark plug gap causes the coil to run hotter. As heat "from the engine" and from the the electricity generated by the coil cause the break down of the insulation in the wires inside the coil and cause them to fail he says the spark plug gap is important.
Pretty AWESOME video my friend
Thank You...
Cheers again from Calgary Steve! I have been telling customers and friends alike this for years. Funny how few believe me and instead buy into the BS. But seriously man, Lucky Lager? More like Yucky Lager, lol!
Good video Steve. Could you do a followup video showing proper use of spark testers and maybe recommend a decent brand? Thanks
Yeh, and clarify that they're not testing spark plugs: they're testing the ignition system up to but not including the spark plug... I think! At least I'd like that to be clarified for me!
Thanks Steve, from France.
Good point John. I should have expanded on your note as well as I often check for spark by grounding the ignition lead with a tester. I found the automotive type dont work that well for two stroke engines.
Cheers. Here tapping my dos xx to your cold one.
Rock on!
Thanks for the videos, because I was sweating it. I have a engine in a vehicle that has no paperwork or information and the plugs are shot. So I guess I'll do better 30 and 45?
It's a older 302 fuel injection engine in a Jeep . It's a custom build With no documentation .
Honestly whichever was the first the engine sounds like is running much better than the second one. ☝🏻
One word, WOW!
I was pretty surprised too!
Lesson is, if it wont start, dont spend all day fiddling with spark plug gaps. cheers
Right on
