Float Level Adjustment

  1. Fabricate float level gauge as shown. See Fig 1. Adjust fabricated gauge to specified height. Remove air horn assembly from carburetor. Insert gauge into outboard holes in air horn. See Figure.
  2. Check clearance and alignment of floats to gauge. Both floats should just touch gauge. Align floats, if necessary, by gently twisting. Adjust float clearance to gauge by bending primary needle tab down to raise floats and up to lower floats.
    NOTE: On Police models, it is necessary to set each float independently.
