Small engine mechanic’s are actually better engine tuner’s than most automotive mechanics

Good videos Jeremy. A plug can tell you a lot. We used to tune our race engine by looking at the plugs.

Good video, it always amazes me how so many people never change their air filters.

Wow. Great video. Straight to the point, with clear explanations. You have a gift for teaching. Thanks for posting. Cool Oakley’s. Subscribed.

Awesome job explaining whats happening with each plug

Thanks for the video, I have a 1987 TRX250X with low compression and the plug was fouled out, most people don't associate the two, you're the first video that said a spark plug was fouled from low compression, no I gotta figure out if it's piston rings or bad valve

Quite true, several years ago i changed spark plugs on an i6 and noticed oil on two of them. The engine ran, but definitely less ideal. I think it's simply because the spark plugs are the only thing easy accessible in the combustion chamber.

I learned a lot from you! My 2016 car sparkplug is still clean at 64k odometer, thank you for sharing this!

Bought a set of plugs at a local parts store and got home only to find the assholes sold me used plugs and of course I couldn't take 'em back. My fault for not going over each box. Lesson learned.

Excellent !! went even further than I thought.. Much appreciated, I learned a bit here, will need to remember, ty !

Love the video man. Not many engine guys read plugs these days!

Thank you so much I really never knew how to read different scenarios . Very helpful :)

This was fascinating. You remind me of hanging out with my dad in the garage. Love your videos.

That is very good information thanks for sharing this…👍👍👍

Nice plug tutorial chap, thanks.

Very valuable info. Thank you

I always check the spark plugs in the first season . I’ve seen spark plugs that is all black and i always replace the new spark plug in my Echo equipment .I service all my equipment before spring clean up

this was super helpful, thank you!

wonderful, thank you for this video brother

My old Honda gx110 has a black oily looking plug. It burns some oil but still runs good. The exhaust smells like there is too much unburned fuel sometimes.

Thank you sir. On my way to my dealer for an explanation after 1700 miles and one plug that looks like the second to last one, wet below the nut on gap side. 2020 Fat Boy

Very helpfull, thanks!

Is it normal for the thread to have a bit of engine oil?

Thank you for a Spanish commercial even though I'm on English

do you prefere the v groove over the flat spark plug

I ordered a Husqvarna 128ld. Whenever I got done breaking it in I noticed that it sounded very rich in the low speed needle so being the mechanic I am, I leaned it out and made sure it sounded a bit rich in the high speed needle and it did so I started to use it. Whenever I was done I let her cool off and then I took the plug out to see what type of mixture it was running at. and to my surprise 1/4 of the porcelain was black and the rest was still white. So I tried to richen the high speed a bit more and after holding the throttle fully for about a minute I took the plug out again but it was the same color and instead of it being dry carbon around the threads, it was a bit wet. Does it take more than 30 minutes for the color of the porcelain to change? And also does anyone know the oem specs of the needles?

Awesome information and diagnosis of spark plugs & possible engine performance as a result of inspection. Well done!

thanks. It would be useful to see how a good used spark plug looks like.

Hello!! I have a Sthil fs94r and it’s revving up then completely shutting off,then takes forever to crank back up and then it won’t rev up at all. Spark screen has been cleaned but didn’t fix anything. Any tips?

Well damn it man guess what I'm going to do I'm going to go pull some plugs and watch the video again and see where I'm at. My wife's going to help we were both watching thanks here we go. I want Cocoa Brown

Good video, lots of great info. Quick question, do you think its ok to use a Champion plug RCJ6Y in place of a NGK BPMR8Y that I removed from an Echo leaf blower? The plug I took out was dry with a redish brown color. Thanks

Nice video Jeremy, you have sparked my interest. Ha!!

Excellent video. New subscriber!

I enjoyed your video but you didn't really seem to explain why. The spark plug with low compression you said had the correct fuel mixture. What on that spark plug told you the fuel mixture was correct and the compression was low. Would not the same spark plug be an indication of too rich of a mixture? If so how can you tell the difference

Any idea why your last few videos show up and then switch to "Private" and can't be viewed?

Does spark plug really increase power comparing two different sparkplug and bnew condition?

This guy is awesome

I bought a bike that has been sitting for 10 years and when I got it the oil was all black as well as the spark plug all black and full of soot. What do I need to do before replacing the spark plug with a new one? Should I clean the inside where it sits or spray it with something first? I've changed the oil and gas and cleaned the carb. The bike ran very bad before and died when reaching 4:th gear after some time and when riding it for a while. So I have it taken apart now since I will be replacing the petcock since it was leaking.

A couple plugs have a little bit of oil on them? What could that mean? Valve stem seal? Cover gasket?

Just a suggestion, but can you also show what a perfectly running plug should look like? Thx.

Good info bro cheers

Great info

Very interesting

Hi can I send you a video of my spark plugs if you can tell me how it's running . I just deleted my catalytic convertor and now it seems it's running to lean and it has slight hesitant and little misfire .when you put under loan only

you should actually show as well a good old spark plug, as an example of a good looking engine with old used spark plug, so people can judge a good from bad engine

Hello. Can you help me tune the carburetor on the 4t scooter? The problem is in the composition of the mixture, the candle is clean, as if there is not enough fuel, I raised the needle, the level in the chamber is set, the nozzles are clean, the valves are set

I have a question my evinrude 200 2 stroke outboard it has some oil on the spark plugs it looked wet but very light is thrat something alarming

generator fouling new spark plug instantly with dry black powdery deposits , any ideas , do I need to increase decrease air/fuel mixture have done approx 1800 hrs use?

I am trying to get a Honda 185s Big Red running. It only runs well on choke and the new spark plug after 10 mins of running smelled like burnt electronics? It seems lean? thoughts?

Perfect...Thanks

great vid. Thank You

own a honda city 2019. mileage only 27000 km , honda dealership recommends to change at 100,000KM / 5 years. pls kindly advice. have no issues changing them as per honda service recommendation... but i would like to know if iridium spark plugs are actually a time based thing. thanks.

Hello sir. I have a 2 stroke dirtbike. Has good compression. But the plug is saturated. You think the carb is the issue? Thanks.

Is the last one rich on oil or rich on gas pu rich on both?

I have a problem with a lawnmower where it runs but idles somewhat rough, and it won’t cut grass that well. I took the spark plug off and it was wet, cleaned it off, put it back in but the same thing happened spark plug was also wet again.

Awesome. Thanks so much. What’s your method of cleaning plugs?

Nice to meet you my brother i like this video! I removed cylinder 1 spark plug and im frustrated because im not comprehending how to read the condition of cylinder 1 spark plug so i can know what is going on inside the vehicle (2003 DODGE CARAVAN SE) engine, can you help me, please?

How come top radiator hose never has a pressure on it an gouge go to one temp an stay never even barely moves

Does this logic also apply to 2 stroke engines ? Or are we talking about 4 Stroke only ?

Right on!!

Awesome

Mid to dark grey or Cocoa/tan is good ;)

What about a plug that quickly goes to charcoal black?

The first one, the acceptable one.. That is an interesting electrode.. what brand plug is that?

2:35 if the gap is too wide can't you adjust the gap?

Why not just clean and adjust the gap why replace if its still good?

Mine are pure "blister white" as you said. What actions should i take to care for my engine? She's almost at 200kmiles i dont plan to let her go any time soon. I have to replace and remove the valve seal and the spark plug tubing gaskets becuz im tracking down a crank no start issue and found my plugs are crispy white and plug 3 is drowning in oil. Any help is appreciated.

How were you able to tell if that was oil or fuel on the spark plug? Mine is very wet on the threads like your last one but it was a much lighter color. I was assuming it was oil.

Can you make a video and help me, I have a Husqvarna two-stroke leaf blower. I have clean the carburetor got a new spark plug check the magneto gap and a new fuel filter and cleaned the air filter and the primer bulb is new. It’s hard to start cold but it will fire up on full choke and then as it warms up it dies off and won’t start back up from there I end up flooding the motor just trying to start it. I hope you can help and have an idea of what’s going on and how to fix it.

Very nice video; keep up the good work I have a Honda Car with 1.3 IDSI engine having 8 spark plugs. The engine is powerful but the only center two spark plugs get really black after one week driving. I replaced old park plugs with new NGK spark plugs but the problem is same. Can you kindly guide which is causing this issue?

Good times..👌

SUPERB!!

I'm bad for never changing spark plugs

So if there’s nothing on the plug that probably means I’m not getting fuel?got spark

I used a wd-40 in cleaning a spark plug, what i the effect if i repeated it more frequently?

Mine runs too rich idk how to fix it when I turn it on the idle builds up idk

Thank u smart

When mechanics say an "engine is running rich" what does that mean in layman terms

Thanks

Spark plugs is like lab work for humans, it talks.

When reading plugs should I be starting with a new plug? Like if it’s rich, can I make a carb adjustment put the same plug in and will it show too lean? Or should I put a new plug in?

Can you tell the sex of the person operating the equipment?🤪 great video!👍🏻

Mine was white what could that mean 😢

My motor ihave changing some prugs but misfire

Low compression issue is my engines problem then.

I put a new battery on my ski and it starts good on the first start but after awhile riding it struggles to turn I have to wait till it cools down a little I was wondering if it was the spark plugs does anyone know ??

Should also show a plug from a good engine

Omg my 4 spark plugs are all different and each one like on of these… ☹️

Can i replace only 3 out of 6 plugs? 3 are hard to get to

❤

Common issue here is ngk plugs upgrade ya plugs .

A spark plug is the "sole" of an engine.

Hii dear friend👭👬👫

Sparks don't lie

Show the top end of the plug will ya!

Good video but should have compared it to a well tuned one instead of a new one

Cap the burnt stuff is the carbon

Don't you think it would be valuable to show what a used plug that was in a good running car should look like?

A little different from an automobile engine, but similer(4 stroke)
