C-150 pilot discovers after performing some basic flight maneuvers; that the engine will only produce partial power. A landing on an available dirt road is chosen as the least risky option and accomplished successfully.

Narrative:
Introductory flight in C-150B. After one full-stop taxi-back landing; and one touch-and-go; proceeded west-south-west of the field for maneuvers. After clearing turns; steep turns; one chandelle; one power-on stall; and one power-off stall; upon power application during power-off stall recovery; the engine produced only partial power. Carb heat was applied during low-throttle and idle-power maneuvers. Pilot not flying noted engine not making full power; and began pumping throttle; this restored some power temporarily. I (pilot flying) checked and adjusted mixture to full-rich; cycled carb heat from on to off to on; and began turning towards an airport. It became apparent the remainder of the flight would be at partial power; so we chose to make a precautionary landing on an available dirt road in our vicinity. Landing on road was normal (full flaps; smooth touchdown; full braking to a stop). Engine remained at partial power throughout approach and continued idling after landing until we shut it down. We kept the fuel on since the engine continued to run; and we preferred to have the option of using the partial power remaining. There were no injuries; property damage; or damage to the aircraft.
