Adjusting Float Level
With air horn upside down and gasket removed, allow float to hang by its own weight. See Fig 1 . Measure distance between top of float and air horn gasket surface. If distance is not .42-.46" (10.7-11.7 mm) for vehicles with A/T, or .46-.50" (11.7-12.7 mm) for vehicles with M/T, bend float seat as necessary.
