Float Drop

  1. Hold air horn upright. Allow float to hang down by its own weight. Ensure gasket is in place.
  2. Using a depth or "T" scale, measure distance from air horn gasket to index point at toe of float.
  3. If adjustment is needed, gently bend float tang up or down. Install new gasket, replace air horn. Start engine and check for leaks.
