## Discrepancy

DURING BASE LEG, PILOT IDENTIFIED ROUGH RUNNING ENGINE AND THEN COMPLETE ENGINE FAILURE.  PILOT MADE AN EMERGENCY LANDING IN AUXILIARY AIR STRIP.  AIRCRAFT WAS TOWED BACK TO MAINTENANCE FACILITY WHERE MECHANIC ATTEMPTED RESTART.  ENGINE STARTED BUT WAS NOTED TO BE ROUGH RUNNING WITH AN EXCESSIVE AMOUNT OF FUEL COMING FROM CARBURETOR.  ENGINE WAS IMMEDIATELY SHUTDOWN.  CARBURETOR REMOVED AND SENT TO AVSTAR FOR EVALUATION.  IT WAS DETERMINED THAT THE SOLDER WELD IN THE BRASS FLOAT FAILED ALLOWING FUEL SATURATION INSIDE THE BRASS FLOAT.  THIS CAUSED THE FLOATS TO SINK DURING FLIGHT.  THIS WAS FIRST OCCURRENCE WITH BRASS FLOATS FAILING.  PLEASE REFERENCE SECOND OCCURRENCE SDR NR 2020FA0000334.
