@@VintageEngineRepairs Well, 150 psi without ignition, but you've got to add in the "explosions" happening about 150 times per second as well as the strain on the epoxy from the heat. I would definitely not be looking directly down on it!
If nothing else that was fun and interesting at the same time. I thought the orange was more fierce when you adjusted the carb, maybe just my imagination though. You come up with some interesting ideas
Thanks for watching and sharing Al! I’m still scratching my head. I think the burnt colour of the epoxy that turned orange didn’t help, but interesting none the less!
You might consider a counter top epoxy. Most of those can handle heat up to around 500f. And they are clear. I've used it for countertop coatings. Also consider a tungsten wire electrode.
I have a colourtune and your plug offers much better visibility of the colour. I had hoped that you'd come up with some sort of DIY glass that could handle the heat. As far as handling the heat goes I would be cautious running it for too long as eventually most epoxies will melt and at that point it will go projectile.
Brilliant Tom! It honestly looked more orange as you tuned the carb, but that might have just been the epoxy degrading. Great experiment indeed. BTW, that green color in the end was the effect of subtractive colour mixing theory. Interesting concept as colour mixing lights is really an additive process, hmmm, I'll have to wrap my brain around that for a while.
I used to have a Gunsons colourtune kit, it was stolen from me by an ex flatmate (along with a lot of my other parts, equipment), I had many hours of fun with it.
i would add Acrylic sheet and add the epoxy then it wouldn't burn. i seen they use Acrylic sheep to see combustion chamber and there's no damage to the Acrylic.
@@VintageEngineRepairs Update, using polycarbonate sheet works but using epoxy adhesive to test doesn't work as it nearly missed my eye. so using a polycarbonate sheet with a steel insert to hold the sheet in would work but i won't test anymore as it requires machne work.
I expect the 2 stroke oil has affected the colour, making it always orange from lean through rich. Great video from a fellow lefty!
That’s a very interesting point!! Maybe you’re spot on! Thanks for sharing :)
Wow, I can't believe it actually contained the pressure. Very interesting and fun video!
It’s pretty impressive isn’t it! It would have been about 150 psi lol.

Some great advice, thanks Jim!
Seen just about everything see through on an engine, but never a spark plug, very cool👍👍👍
Glad you enjoyed it :)

Thanks for sharing! I agree, I wouldn’t want to run it long because it will let go.

Couldn’t agree more Stella! Thanks for sharing your thoughts and understanding on the glues too :)

That’s awesome! Did you rate them as a good tuning device?
@@VintageEngineRepairs Apart from it being stolen from me (that part wasn't awesome) it was a great bit of kit, they are pricey but well worth having.
Company called Gunson made a kit Colortune kit, I have have mine after 40 years and made 4 stroke engines.
Yes :)
Very cool.She actually ran great.Great idea
It did didn’t it haha
That was very impressive Tom well done 👍
Thanks Nev, it was fun to mess around with it :)
Tom I like it you did a great job on it 👏
Thanks Mark!!
That was neat Tom, the stuff you come up with!! 🤣👍
Haha thanks John! Not my idea I must admit! Gunsons made the original, I just made a cheaper version😂 thanks or watching!
Anytime brother, either way it was still cool. 🤣
That was VERY INTERESTING!!!! Thanks for sharing!!!
You’re welcome!
I don't care if it helps tune the motor. That was VERY cool!
Hahah thanks Bill :)
Very nice sir!.😄 What if some kind of glass or acrylic is used in the center, while securing it with a little bit of epoxy..
Hey :) it was just epoxy!
The spark plug mafia, AC, NGK ND, Champion.....they're comin for ya! 🤣
Yer a madman.👍🍻
I’ll keep my head down 😂 thanks for watching!
Very good video for Sassy Madam lol Really good work Tom
Thanks for watching Brandon 👍
Nice one Tom . Off to go tune the MG carbs😀
Haha exactly 😂
i would add Acrylic sheet and add the epoxy then it wouldn't burn. i seen they use Acrylic sheep to see combustion chamber and there's no damage to the Acrylic.
Interesting, it must be a specialist, high resistance one though! I know the colortune plugs use glass

Thanks for watching Dennis :)
Like a mad scientist 🔬⚗🧪 COOL 😎
Haha thanks Bill, glad you enjoyed it mate
Good fun Tom!
Thanks Kenny, something a little different!
Hi long time since heard word gunsons colour tune
Thanks for watching! The original is superior and not too expensive either, but I had fun.
