I have been trying to find out what this means on the internet with no luck.
I only found one thread somewhere with the picture moved, and someone said the plug was colored on the intake side and white on the exhaust side, indicating that there was not enough gas, and to increase the main jet size.
I'm not sure if I buy that I need to increase the main jet because I already have had it one up and it was too rich. I would think that if the jet was too small, there wouldn't be tan anywhere. Meaning I don't see how that has much to do with the color only going half way around the plug.
I have an expansion chamber if that has anything to do with it?
Here's some pics... Sorry about the lighting.
