Narrative:
Routine oil/filter change requested by owner; performed by local maintenance operator (a&P). Owner to perform engine run-up; a&P to perform post run-up leak check. Run-up (on non controled movement area) was normal and aircraft taxied back to maintenance ramp. Upon exiting aircraft to chock aircraft; fire was observed at area on cowl flaps. I (owner) secured CO2 fire extinguisher and called 'fire.' after numerous discharges of CO2; flames were extinguished. Cowling was removed and source of fire was found to be an oil rag placed under oil filter to catch drips which had fallen down to exhaust pipe and had not been observed or removed by a&P after oil change. Oil rag had ignited and was extinguished as stated. A&P acknowledged his oversight.
