Narrative:

Climbing en route through 5000 ft, right engine lost partial power. After determining that it would be safest to turn back to kbuf, I advised the ATC controller that 'I would like a vector back to kbuf for a visual approach.' the controller then asked if I had a problem. I advised him about my situation and said it was no problem, just a 'rough engine.' ATC then asked me for the standard information for emergencys. I advised him twice that I did not wish to declare an emergency. He still insisted for the emergency information which I gave him. I think it was unclr whether an emergency was declared by the controller or not and if I got priority or not. I have to add that the controller was very helpful.
