I was told by an IA that the most wear of our engines occur during initial startup due to lack of oil initially. He said that when starting, full throttle should not be used with the fuel pump on high but rather a “crack” so that the fuel flow maxes around 8GPH vs 29GPM. He said when full throttle is used, too much fuel is introduced causing RPMS tp shoot up to 1200 RPM. He said on start up you don’t want RPMS to go past idle. Ive tried this but can’t seem to get the engine to fully start as it only sputters and stalls. Since Ive owned the plane Ive started as the POH suggests and yes, the RPMs shoot up around 1100-1200 initially but as soon as it starts I immediacy pull back to 1000. I fly more than regularly with an average of 2 flights a week so I wonder if some residual oil is still providing some initial lubrication. Engine has about 200TT since factory new.
Has anyone heard this ? Anyone with higher time on their engines using the POH starting procedures ?
