Analysis

While in lvl flt and cruise flt configuration the plt stated that the eng suddenly began to get rough he noted that when pwr was partially reduced the roughness terminated. When the mixture was leaned the eng died momentarily. He rptd that the eng RPM was maintained abt 2450 RPM but only 15 to 18 in of manifold pressure could be obtained. On short final to a selected field the plt said he remembered to switch the position of the fuel selector. Pwr returned to a normal lvl and the roughness disappeared. The plt elected to pick out another more suitable lndg site and the acft was substantially dmgd during lndg. No mech malf of any eng or acft component was located which might have brought abt the transient eng roughness which the plt rptdly experienced.
