Aircraft
During the take-off roll or just after departing the surface of Runway XX; the engine began to not develop full power; RPM's were fluctuating between 2000 and 2200. The take-off roll was sluggish; but not excessive. Upon noting the decreased engine performance; decision was made to abort the take-off and land on the remaining surface. We advised ATC. The subsequent descent and landing were un-eventful. Upon exiting the runway; I requested and was granted clearance for a high speed taxi on an adjacent taxi-way that was clear of traffic. I performed this high speed taxi at full power for a few seconds and noted similar indications; RPM's fluctuated between 2100 and 2300. Oil pressure; oil temperature; and cylinder head temperature were normal. Oil was observed at 10 quarts during the pre-flight. Pre-flight and run-up were completed with a few slight abnormalities.The engine start was difficult and priming was required. A normal start in this aircraft doesn't require priming beyond a couple pumps of the throttle. However; the primer plunger was needed to start the engine in this case. The weather was cool in the morning and the aircraft had not flown. During run-up; the carburetor heat check produced RPM's barely 100 lower than without carburetor heat. After run-up; the engine idled at a much higher RPM than usual (1000 vs. 650).
Reporter stated the propeller control cable slipped from mount.
C182 pilot reported that a partial loss of engine power on takeoff resulted in a precautionary landing.
