You got it, once you loosen the lockscrew (just a bit or it will spray fuel everywhere, lol) turn the seat adjustment clockwise to lower the fuel level or CCW to raise it.
You would think they would have changed, modified, invent something that would not let the fuel come out at all doing a bowl adjustment by now. Spraying fuel on a hot running motor is not the safest thing in the world. I caught on to the trick of not backing off of the locking nut as much in order from leaking fuel ... but it's in the back of my mind... FIRE!
