Narrative:

On level out going to practice area; the engine began to hiccup/surge and then loose partial power; I notified tower of my intent to land immediately; and was cleared. The power loss was momentary at that time. It occurred again; and I declared an emergency to get on the ground as soon as possible. Tower asked the questions re souls aboard and fuel; which I answered. They also asked if I wanted to have them roll equipment. I was still developing power; and could make the field and so I declined the equipment rollout. Power hiccup/surge occurred a third time on descent; but we never lost power completely. On touchdown; tower indicated 'good job' and on taxi; tower asked; 'are you canceling the emergency.' I responded yes. I taxied to my mechanic's hangar and now await word on why the power surge happened.
