I'm a student pilot with 28 hours flying time. Flying from FBO at cak in an small aircraft. What happened was the fuel tank selector switch got stuck between on and off. This allowed enough fuel through to have fuel pressure at low rpms (below 1800). So during engine runup I had fuel pressure. But once departed from runway 19 and climbing out on heading of 260 degrees, the engine started sputtering and coughing and producing no fuel pressure. I checked everything but never switched over the fuel switch. Both tanks were full and the switch looked like it was pointing to the left tank (but it was partially off). I declared an emergency and flew back to cak where the problem was discovered by a FBO maintenance man.

Narrative: I'M A STUDENT PLT WITH 28 HRS FLYING TIME. FLYING FROM FBO AT CAK IN AN SMA. WHAT HAPPENED WAS THE FUEL TANK SELECTOR SWITCH GOT STUCK BETWEEN ON AND OFF. THIS ALLOWED ENOUGH FUEL THROUGH TO HAVE FUEL PRESSURE AT LOW RPMS (BELOW 1800). SO DURING ENG RUNUP I HAD FUEL PRESSURE. BUT ONCE DEPARTED FROM RWY 19 AND CLBING OUT ON HDG OF 260 DEGS, THE ENG STARTED SPUTTERING AND COUGHING AND PRODUCING NO FUEL PRESSURE. I CHKED EVERYTHING BUT NEVER SWITCHED OVER THE FUEL SWITCH. BOTH TANKS WERE FULL AND THE SWITCH LOOKED LIKE IT WAS POINTING TO THE LEFT TANK (BUT IT WAS PARTIALLY OFF). I DECLARED AN EMER AND FLEW BACK TO CAK WHERE THE PROB WAS DISCOVERED BY A FBO MAINT MAN.
