Probable cause

Fuel starvation caused by a sticking needle valve which was softened by contact with automotive fuel previously used to operate the engine.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Fluid,fuel - starvationCause
Fuel supply - improperFactor
Forced landingDescent - emergency
Nose overLanding - flare/touchdown

Analysis

While climbing to cruise the plt reported the eng lost power then quit. Attempts to restart were unsuccessful. After touchdown during the forced landing, the acft nosed over. After a temporary fuel supply was connected to the eng, attempts to run it were unsuccessful without pumping the throttle. The carburetor was removed & disassembly revealed a sticking needle valve. After reassembly & installation, the eng operated normally. Prior to the acft purchase by the flight school, the engine had been operated using automotive fuel.
