I always mention cooling in these threads as cooling airflow, or more clearly the airflow through the cowl is so closely tied to how the resulting air pressure affects the carburetor. The various forums are full of threads about engines that run hot and run rough. The P-51 being the worst offender due to its narrow and tight cowl and owners that refuse to acknowledge the need for proper airflow. The YAK or any plane that has a huge round cowl being a close second. Yup, two extremes from each other and both extremes present their own unique cooling and pressure challenges.
