Narrative:

I was on climb out from the airport when; suddenly; the right engine began running rough. I immediately took action to recover the engine. The engine [stopped developing power]; so I put the mixture forward and turned the boost pump on. At that time I called the tower and declared an emergency. I then proceeded to turn the carb heat on and was going to attempt to restart the engine. Applying carb heat was sufficient to recover the engine and it started running rough again. While descending the engine began to run smoother. Upon landing; the engine was running and I terminated the emergency. I taxied in and had a mechanic look at the engine.
