I need some help. I have a G62 and Fuji 43 and both carbs stick out slightly from the cowl. After a flight, I have a lot of siphoned fuel and fule down the side of the plane. I picked up a couple velocity stacks from B&B which are fully radial adjustable. Where should the angle on the inlet of the stack be positioned? Facing forward, backward, up, down? Also, will there be high or low end needle setting changes required with the velocity stack?
