## Discrepancy

(CAN) WHILE PRACTICING FORCED APPROACHES, FULL POWER WAS APPLIED FOR A GO-AROUND.  THE ENGINE DID NOT RESPOND AND STARTED TO COUGH, POWER WAS REDUCED AND THE AIRCRAFT LANDED.  POST-FLIGHT INSPECTION FOUND A SMALL PIECE OF BRASS TUBING IN THE NR 1 SPARK PLUG.  FURTHER INVESTIGATION FOUND THE CARBURETOR ACCELERATOR PUMP DISCHARGE TUBE WAS MISSING.  THE CARBURETOR WAS REPLACED.
