DURING THE INITIAL CLIMB, THE PILOT EXPERIENCED A LOSS OF ENGINE POWER, AND WAS UNABLE TO CONTINUE TO CLIMB OR MAINTAIN ALTITUDE. THE PILOT STATED TO FAA INSPECTORS THAT HE CHANGED FUEL TANKS AND ADJUSTED THE MIXTURE TO NO AVAIL. HE LANDED STRAIGHT AHEAD INTO UNSUITABLE TERRAIN AND NOSED OVER. INVESTIGATION DETERMINED THAT NUMBER 2 CYLINDER EXHAUST VALVE HAD STUCK OPEN FROM CARBON BUILD UP. A MANUFACTURERS SERVICE BULLETIN REGARDING THIS POSSIBLE PROBLEM HAD NOT BEEN ACCOMPLISHED AT THE RECOMMENDED TIME, NOR WERE OTHER ITEMS OF IN SERVICE INSPECTION/INFORMATION REGARDING VALVE STICKING ADDRESSED ACCORDING TO THE RECORDS AVAILABLE.
