PIC narrative:
Flying at 2000MSL 17:06 the RPM dropped from 2300 to idling at 1000.
Until securing the aircraft 100AGL above the ground, the rpm’s would continue the oscillation (2300-1000) with different intervals (1-8 second intervals) of idling before going to 2300 for a short time.
PIC stated mixture which was full rich, fuel selector both, magnetos were both, carb heat turned on, oscillated the throttle to check for response, which was unsuccessful
PIC made an emergency landing at 17:08L
Fuel tanks checked for water/contaminants, none found
Last fueling point was requested to check fuel storage; reported all normal
No maintenance anomaly or operational cause determined
