The NTSB's narrative final · quoted from the NTSB record
The pilot reported that as he reduced the throttle, while in a descent, the engine quit. He attempted to restart the engine without success, and elected to make an off-airport landing. Post-accident inspection of the carburetor revealed that the carburetor was adjusted to an excessively lean mixture setting, precluding stable operation below 1500 RPM. The pilot reported that prior to the accident flight, he adjusted the carburetor in an effort to overcome an excessively rich mixture setting.
