Analysis

Initially, after a top overhaul, the eng would not run. The mechanic removed the carburetor & found a piece of silicon. After reinstalling the carburetor, the eng operated normally. The plt then took off on a maintenance test flt. As he began a descent back toward the arpt, the eng stopped running & would not restart, except it restarted momentarily when he operated the primer. During an emergency landing, the acft hit a rice field levee & nosed over. An exam revealed that the fuel line had become disconnected from the carburetor at a threaded fitting. A laboratory exam of the threaded fitting revealed a lack of smearing or scratching that would have been present if the fitting had been properly torqued.
