However, if you are getting coated spark plugs, can you tell us what they are getting coated with?
I assume they are black but are they coated with soot, oil, fuel? Are they wet? Can you get some pictures of the plugs when they are fouled?
Below is a chart showing plug issues. Please run through this material and let us know if you can get pictures of the plugs.
Depending on what they look like will determine what direction we will go. Thanks
