Hi Rodney,
The engine is inside the cowl, but the velocity stack is outside the cowl. Without a velocity stack the opening of the carb is just slightly past the cowl, if that makes any sense. I can certainly turn the velocity stack around and try it with the cut facing rearward, so that the air is not forced into the opening.
