Say again s l o w l y, your comments about carb heat interested me. I was taught "carb heat to cold" in the last 2-300 feet, so that isn't a problem. And I know that generally carb heat results in a reduction in power. However, in a C182 that I fly the difference the carb heat control seems to make is really minimal and perhaps hardly noticeable at all. Is this likely a function of that plane's engine/carb design or something else? It seems unlikely (though not impossible obviously) that it is faulty because it has been known to clear carb ice.
