THE PLT STATED HE HEARD A 'BOOM' AND EXPERIENCED A PARTIAL POWER LOSS WHEN HE WAS ABOUT 10 FT ABOVE THE RWY DURING THE INITIAL TAKEOFF CLIMB. HE WAS ABOUT HALF WAY DOWN THE 3000 FOOT RWY AT THIS TIME. HE ABORTED THE TAKEOFF AND LANDED. HOWEVER, HE WAS NOT ABLE TO STOP THE ACFT UNTIL IT HAD OVERRAN THE RWY AND COLLIDED WITH A DITCH ABOUT 30 YARDS BEYOND THE DEPARTURE END OF THE RWY. SUBSEQUENT EXAM REVEALED THE ENG WOULD OPERATE NORMAL AT LOW RPM BUT AFTER 20 SECONDS AT TAKEOFF POWER THE FUEL MIXTURE WOULD BECOME TOO RICH AND A CONSIDERABLE DROP IN RPM WOULD OCCUR. THE CARBURETOR WAS DISASSEMBLED AND EXAMINED BUT THE CAUSE OF THE POWER REDUCTION WAS NOT NOTED. ALSO, THE CAUSE OF THE REPORTED 'BOOM' WAS NOT DETERMINED.
