On a kohler 18hp twin that's on a craftsman rider if the plug is oil wet than I can assume the rings are bad and engine needs to be rebuilt? Do I need to buy a compression tester?
said no one ever 😂😂. There are way more variables to take into account in tuning big engines, specially carbureted engine. No saying small engine mechanics are dumber, just not in the same level. Anyone who has touched a wrench in his life will know. It’s like comparing a house electrician with an electrical engineer in charge of the city’s electric distribution systems. 😂😂
@@hentaibodypillow250 thanks for proving my point. Just like no one says women are better at pulling someone to have sex than man. Easier = less skills required.
Dude I have been saying this too people lately and people just kinda looked at me crazy. My arguing point is this I can make a ford,dodge,Chevy run no problem. Now when you start trying to fix a small engine and make it run good/excellent I personally have to go back and do my research. Even then they give me hell
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
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
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.
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.
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.
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?
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
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?
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.
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
@@jonaaa6059 from Harley, it was a river in Egypt and a hands off statement due to the fact I did my first maintenance with a Harley tech who just opened his own shop. My assessment was faulty piston rings causing a type of blow back coupled with the engine burning rich. Finally a possible faulty install. So far, no issues with the replacement Screaming Eagle plugs and wires.
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

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 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?
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?
The brand new cmh is what every plug electrode I’ve ever seen in Canada look like except fine wire plugs, they have a needle.. did you add the notch/groove?
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.
I have 125b husqvarna leaf blower,doing the same thing,did a vacuum and pressure test with a mityvac the carburetor would not hold pressure,showed to be the needle leaking,replace the carburetor and it runs great.
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.
Modern automobile engines tend to run what looks like "lean" according to old plug examination standards, so that's actually normal. The one covered in oil isn't good. You probably have bad rings or sludged up oil control rings or drain back holes on that piston.
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
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?
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.
It means that in the air fuel mixture, there is more fuel than needed that results in black soot. This may be due to bigger jets or low float height in the carburettor. Other possibility is, it can also be correct amount of fuel but less air due to clogged air filter which again results in to black soot.
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 ??
@@THEMOWERMEDIC1 i just bought the car at 100k mi. I figure it needs plugs changed. Just wondering if changing 3 is gonna causr any problems, to replace the back 3 i would have to loosen motor mounts n tilt engine forward. Its a fwd chevy uplander 08

Good videos Jeremy. A plug can tell you a lot. We used to tune our race engine by looking at the plugs.
remember a 'see thru' plug that you could see the mixture when it fired....always looking for the blue.
Can you do the same with a generator...

I used a wd-40 in cleaning a spark plug, what i the effect if i repeated it more frequently?
No harm will be done. I use carburettor cleaner and a toothbrush to clean my spark plugs, then use compressed air to finish off the cleaning process.
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
Why not just clean and adjust the gap why replace if its still good?
What about a plug that quickly goes to charcoal black?
2:35 if the gap is too wide can't you adjust the gap?
Thanks

Good times..👌
So if there’s nothing on the plug that probably means I’m not getting fuel?got spark
Thank u smart
Mine runs too rich idk how to fix it when I turn it on the idle builds up idk
When mechanics say an "engine is running rich" what does that mean in layman terms
It means that in the air fuel mixture, there is more fuel than needed that results in black soot. This may be due to bigger jets or low float height in the carburettor. Other possibility is, it can also be correct amount of fuel but less air due to clogged air filter which again results in to black soot.

Hii dear friend👭👬👫
Good video but should have compared it to a well tuned one instead of a new one
The first plug I showed was about as good as you’re going to get with a dirty old two cycle engine
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?
Most def.
A little different from an automobile engine, but similer(4 stroke)
