Read my Plugs
Hot/lean but ok - good - a little rich but ok - too rich. Take this with a grain of salt, I'm not an expert on plug reading. You do want that tan on the insulator, kinda like the 2nd from left. What kind of conditions have these plugs seen? What do you mean chronological order? You've put 4 different plugs in 1 hole?
