Colortune on M102 engine

Does anyone have experience of using a colortune plug on a M102 petrol engine?
Plug recess is deep so wondering if colour can be seen.

Yes i had one back in the 70s but still avaliable to-day .They do come with a tube that fits over the plug, a periscope type idea and you can see the mixture ideal mixture is bunson blue spark ,but i used mine without the scope tube,, you can see if better in the dark.And they were good on the older type carb engines I think you will find it very usefull. I thought about getting me one for future use .

This is a retro ride .
