What was found

DURING ANNUAL INSPECTION NOTICED DARK STAIN BETWEEN FLOAT BOWL AND TOP OF CARB (BUT NO FUEL STAIN). WIGGLED AIR BOX AND DISCOVERED THE FLOAT BOWL WAS LOOSE EVEN THOUGH BOWL SCREWS AND LOCK TABS WERE STILL IN PLACE. THERE APPEARS TO BE SIGNIFICANT PLAY IN THE SCREW TO BOWL AREA WHICH IS LIKELY DUE TO SCREWS/VIBRATION WALLOWING OUT SCREW HOLES. WILL REMOVE CARB AND SEND IN FOR OH.
