Float level height is mostly to set fuel height in the emulsion tube well which affects when the main circuit is activated. Higher float levels advances the activation of the main circuit and lower retards it. Since the fuel to the accelerator squirters is mechanically sucked into the pump cavities through the check valve and the check valve closes upon throttle actuation, the fuel volume in the accelerator pump is thereby set independently of fuel level in the float wells.
