Good video, I have been changing sparkplugs in small engines since I was 12 yrs old. I am 79 now. You answered my many questions about the actual condition of those spark plugs. Your explanation of how to test them is the best I've ever heard. Richard Thank you!

Comprehensive,short,smart,simple briefing ,thanks

Your video saved me a lot of time. Yamaha Beartracker 250 ran great after carb cleaning and then would not fire 4 days later. I assumed the carb again, cleaned and rebuilt again with new kit. Still not firing. I checked for spark with inline tester and the tester was getting spark. My spark plug was intermittently failing and your video told me how to confirm the plug was shorted. Thank you.

Great video. Very informative. I used to test spark plug wires by grabbing a hold of them. After getting shocked I sure learned my lesson. Always wear a helmet in case you bang your Head on the hood

Don't know if you'll get to see this comment. I would like to thank you for your video. I have been flabbergasted trying to get my multi function strimmer going. I always thought I was good with engines. I had a good spark on my coil according to my tester; although my plug didn't seem so good. I reset the flywheel gap, changed the carburetor and just about tried everything but change the plug. I had two plugs which looked in perfect condition, but after doing your test with my own multi meter they both had a zero reading, but a plug from a different machine had a 5+ ~ a bit of a coincedence the two plugs being duds. A lot of people would have given up and put it into a repair shop; who would have charged well over for a repair. I still need to get a plug and try the machine but it seems my problem (fingers crossed) could be solved thanks to you.

I've never had a spark plug go bad until today. Fantastic video!!! I was able to determine that one spark plug failed.

Makes sense 👍 Never thought of this before. Thanks.

Thanks for this very useful info. At the VW workshop, we had a spark plug tester back in the day where we tested ALL spark plugs, weather old or new. Now you gave me another way to test them....thanks a million☝️🙏

Learn something new every day. Thanks man.

the best explanation and detailed I have ever seen on YouTube

Thanks man. Needed a quick refresher. Not getting any spark on an old leaf blower. Hoping it’s a easy spark plug, but it may be more than that. Keep up the good work

I have never known to be able to test a plug , very informative.👍🏼

Thank you. I learnt something I did not know before. It is truly helpful.

Here’s something new. I didn’t know people test spark plugs anymore. I haven’t been in an engine compartment in decades let alone know where the spark plugs are, this from a guy who used to be a shade tree mechanic back in the day in Florida. It is good to know that this technology is still available. Good video.

Most informative video I've ever watched on how to test something. Voice tone and cadence make it very easy to digest info. Well done ol chap!

Good video. I replaced one yesterday now I have to compare it to a new one. I will also check the resistor compared to the non resistor. Thanks from West Tennessee

great video sir, this video is very helpful. My generator would not start it only backfires so i thought the engine has spark if it's backfiring but upon testing the plug as you showed, sure enough, the plug was faulty. you saved me from buying a new Generator. thankyou.

Very helpful. Answered all my questions. Thank you!

Thanks it’s a good day whenever you gain a little knowledge ad today I learned something about Spark Plugs I did not know
