Float Level
With air horn and bowl cover removed, invert carburetor so that weight of floats only is holding inlet needle against seat (hold finger on retainer to fully seat float fulcrum pin). Use suitable gauge or "T" scale to measure from top edge of fuel bowl to crown of each float at center (see Fig 1). If float setting not correct (see Specifications ), remove float and bend float lever lip as required.
CAUTION:
Do not attempt to adjust float without removing if from carburetor (inlet needle has synthetic rubber tip which may be compressed sufficiently to cause a false setting).
