KOR engine finally running!

If you are looking down into the insulator and are experienced enough to read the ring colour, then I apologise as one can get a fair enough indication of the AFR.

I was under the impression from some of your previous comments that you do not read the colour of a plug insulator but just tune solely by the seat of the pants.

If I have jumped to the incorrect conclusion I again apologise!
This is also what i thought you meant. you were going by sound and/or how it ran

i have never cut a plug. i always look in them with a couple different lights

Thanks for the respect, it is a new day!
