Who remembers clear spark plugs? You could see the colour of the flame in the cylinder which is very useful when tuning the carby.
I have the Gunson glass spark plugs. They work interesting. But in my opinion, the idle setting works better with the own ear.

Maybe they will help with some unknown troubleshooting?
