SMT ON TEST FLT HAS FUEL STARVATION.

Narrative

THE PROB AROSE WHEN THE R ENG NEEDED OVERHAULING. WHEN THE WORK HAD BEEN COMPLETED; I WAS ASKED TO TEST FLY THE AIRPLANE EARLIER I KNEW THE ACFT ALREADY HAD FUEL IN IT. THE MECH LOOKED OVER THE ENGS AFTER MY PREFLT WAS COMPLETE TO ENSURE EVERYTHING WAS AS IT SHOULD BE. I STARTED THE AIRPLANE AND COMPLETED 2 HIGH SPD (70 MPH) TAXI RUNS DOWN THE RWY. UPON BRINGING THE AIRPLANE BACK TO THE RAMP; THE MECH LOOKED OVER THE ENGS AGAIN. AT THAT POINT I TOOK THE AIRPLANE OFF AND MADE A TEST FLT STARTING WITH CIRCLING THE ARPT AT 2500 FT AT FULL PWR. THE FLT WAS CONTINUED AT FULL PWR TO ATTEMPT TO SEAT THE CYLINDERS. AFTER CIRCLING MCCOLLUM ARPT SEVERAL TIMES; I DECIDED TO FLY OVER TO DE KALB-PEACHTREE ARPT. UPON ARRIVING I MADE 1 LOW PASS ON RWY 20L BEFORE CIRCLING TO LAND. AFTER SPENDING ABOUT 45 MINS ON THE GND I COMPLETED ANOTHER PREFLT AND THEN TAXIED OUT AND DEPARTED ON RWY 20L. UPON FLYING DIRECTLY BACK TO MCCOLLUM ARPT I LOST PWR TO MY L ENG. I LEFT IT WINDMILLING TO CYCLE MY GEAR DOWN. UPON LOSING MY L ENG I WAS 3-4 MI SE OF MCCOLLUM AT 2500 FT. MY R ENG WAS RUNNING STRONG; SO AFTER NOTICING NO TFC IN THE PATTERN; I CONTINUED STRAIGHT IN FOR A LONG FINAL TO RWY 27. AFTER LNDG WITHOUT INCIDENT THE ACFT WAS DETERMINED TO HAVE NO FUEL IN THE L TANK AND ABOUT A GALLON IN THE R. THE SIT COULD HAVE BEEN PREVENTED WITH BETTER KNOWLEDGE OF FUEL QUANTITY AND MORE THOROUGH PREFLT.
