The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he had been flying about forty five minutes on this load of fuel, and estimated that he had in excess of one hour of fuel remaining. While on the first swath run climb out from a field, the engine lost power. The pilot also reported that as the engine lost power, black smoke was seen coming from the exhaust. According to the pilot, the only available emergency landing area was straight ahead. During the post-accident examination of the engine assembly, the engine was started, it ran roughly, and produced black smoke. Further examination disclosed that fuel pressure supplied by the engine driven fuel pump was not being maintained in the pressure carburetor. According to a local mechanic assisting in the examination, the loss of fuel pressure in the carburetor is normally associated with a defective needle assembly in the carburetor. According to the operator, the maintenance records showed that the engine assembly had accumulated 1150 hours of service since the last overhaul. The recommended time between engine overhauls is 1200 hours. The engine maintenance records also failed to show if the carburetor had been overhauled since the last engine overhaul.
