I get exhaust in the driver's compartment of the convertible when I have to drive with the windows up. I also notice the burnt exhaust smell when I stop and idle at a light or stop sign. I've tuned the car, and I've leaned it out as much as it'll go. It's not real bad, but I'd like to eliminate it. I'm running a 218/226 cam; is the long exhaust duration causing some unburnt fuel exhaust? Is there something else I should check?
