## Discrepancy

(CAN) THE CARBURETOR FLOAT PIVOT POINT WAS WORN AND THE FLOAT BRACKET (P/N 136-62) WAS BENT.  THESE TWO PROBLEMS CAUSED THE FLOAT PONTOON TO RUB AGAINST THE CARBURETOR BOWL ASSEBLY. THERE WAS MINIMAL EVIDENCE OF THIS ON THE FLOAT PONTOON. THIS MAY HAVE CAUSED THE FLOAT TO HANG UP.  ALL PARTS WERE REPAIRED OR REPLACED AND THE CARBURETOR WAS RETURNED TO SERVICE.
