Forgot to mention an important point: Fuel pressure supplied by the pump, be it a mechanical or electrical pump, tries to push the needle off its seat and the float down. Consequently, the balance between this pressure and float buoyauncy must occur as you're adjusting the float. As been said, the engine and pump need to be operating during float adjustment.
