Analysis

The pilot reports that the engine of N3587V was run at idle for an extended time before the takeoff was attempted. After several minutes, the engine died. It was restarted and the takeoff was commenced immediately. According to the pilot, the engine was running rough during the takeoff roll but the roll was continued. The aircraft accelerated to near takeoff speed but when lift off was attempted the aircraft would not fly. The pilot decided to abort and during the abort the aircraft entered soft terrain beside the runway and nosed over. Examination of the engine revealed that all spark plugs had carbon deposits and the top plug on one cylinder had a bent ground electrode that was contacting the center electrode. The aircraft was operating on auto fuel but was not modified for use of the fuel.
