Carb Tuning With Colortune

[mrupp]

Has anyone ever used this product? It's essentially a spark plug with a window. By comparing the color of the flame in the chamber to a supplied chart, you are supposed to be able to determine if the mixture is way rich, in the ballpark, or way lean. If you've used it, how did it work for you?

Thanks,

Innovate LM1 wide band. Its the only way to tune an engine, carb or EFI.

The wide band O2 gives an accurate reading of A/F ratio.

If you can find a volunteer to look at that plug while doing a W.O.T. pass, you'll be in business.
