There used to be an article that had pictures of what a spark plug should look like when it is running good. Is it still available? How can I access it? Thanks in advance

CLICK HERE (http://www.eric-gorr.com/techarticles/sparkplugs.html) Not sure if this is the one you are thinking of but it seems pretty good. If not just do a search on google/yahoo/msn...on 'reading spark plugs' and you should find a number of pages.

Thanks for the reply, I had seen that one before. The article (pictures) I was looking for used to be on the main menu of SW. I think it was moved off for some other articles on Sled Modifcations (which I enjoy reading). It was a for NGK plugs proper. Thanks again for the link.

Check this NGK link. This is a good way to read your plugs SWRules click hereNGK (http://www.ngksparkplugs.net/techinfo/spark_plugs/faq/faqread2.asp)
