I inspected my plugs today and found the tips and poceline cones looking almost completely white! (lean) now I read somewhere that platinum spark plugs don't read like normal ones, anyone useing platinums? I would be interested to know what they look like. I'm paranoid that something is causing a lean mixture because of how the plugs look, but she runs well with no knock ping or rattle throughout any range. Shouldn't the plugs be sort of tan like a perfectly roased marshmellow? I tried to run a rich idle 1 full turn out from optimum on each air screw and I increased the primary jetting from 66 to 69 ran about 20 miles and checked plugs still white, just cant seem to get her to run rich, most guys have the oposite problem too rich. But back to my question about the platinums maybe I'm goose chasin'?
