    can anyone help me find an old post?
    it had pics telling what the sparkplug electrode colors tell you
    IE:...too rich, too lean etc
    I remember reading it, but have been searching for an hour and can't find it

    once found...I will delete this post and bump that one up

    Two stroke plugs should be a light chocolate brown, never near white on the Happy Time engines running at 38 or 32 to 1. Or so I beleive.

    EDIT: I think that NGK chart is for 4 stroke plug colors.
