I have a device that goes in series with the sparkplug wire. It has its own

use it to verify spark.

OK..
who's got a "Colortune" ?
Gunninson is the brand of mine ..from merely Olde.
you watch the color of the flame inside the combustion chamber with this
device..
goes in a spark plug hole.
For mixture adjusting, and disagnosis.
I've never bothered to use it yet ...someone just gave it to me a while
back.
