Theoretical scenario. Carb'd O-360 on an RV-4:
I've not tested, but I've heard that the Van's FAB needs to have the air filter in it to keep the engine from coughing and spitting.
If I were to remove the FAB completely, fabricate a direct sealed tube from the cowl scoop to the carb, would that pressure overwhelm the engine's ability to draw fuel from the bowl?
