Great. Thank you.

Excellent and helpful video, I also saw this low rpm “miss” and high rpm “ok” scenario, good to know this tool accurately reproduced this scenario. It’s a shame that this basic phenomena isn’t communicated in so many engine training books and write-ups- everyone should know there is a strong relationship between misfire and rpm for a fouled plug as you showed here.

Hi All. I lost access to my original channel, so I had to start over with a new one here: www.youtube.com/@lonzgarage. I just posted a new vid about installing bearings on a limited slip differential carrier without having to use a bearing/hydraulic press. Pretty cool hack!

Just a narrow strip up the middle of the screen. We view everything in Widescreen these days. Narrow screen looks like crap.

will work with motorcyle sparkplugs?

So how do you know if the spark plug is bad if you don't have a new plug to compare it to. Not a very helpful device.

i mean u could go on youtube and look at some examples of good plugs or clean the plug and gap it and see if it fires better.
