Narrative:

5 mins after departing ZZZ the engine faltered and was only developing about 10 inches manifold pressure. I went through standard restart procedures; but could not get full power. I turned the aircraft towards ZZZ and found that I could make it; given the altitude and power available. As I approached ZZZ from the south I noticed that there was an aircraft rolling on the runway after landing. I announced that it was an emergency and to clear the runway. The aircraft operator stopped on the runway and asked what he should do; which forced me to discontinue my approach and fly a path that would put me in front of the aircraft. I touched down on the east/west runway heading northwest. I continued onto the grass and stopped. There were no injuries nor damage to the aircraft. The airplane was topped at ZZZ; however; after landing I discover that the fuel selector was not in the detent. I restarted the engine and taxied back to the FBO. The airport manager told me that center had called because they picked up the emergency calls. They were satisfied that this as an incident based on the explanation of the event.

I TURNED THE ACFT TOWARDS ZZZ AND FOUND THAT I COULD MAKE IT; GIVEN THE ALT AND PWR AVAILABLE. AS I APCHED ZZZ FROM THE S I NOTICED THAT THERE WAS AN ACFT ROLLING ON THE RWY AFTER LNDG.
