This old chestnut again, I have another question. As stated before the engine is a bog standard naturally aspirated Lycoming 360, no Gammi injectors so I am only concerned with leaning for either best economy which is peak EGT or best power which is approximately 100f ROP of the hottest cylinder.
To date I have only ever leaned it for best power for two reasons. Firstly, I'm an impatient type of chap and like to get to where I am going. But secondly and more importantly, when I get to the cruise, set the MAP/RPM for desired power then commence using the EDM to search for peak EGT the time between the onset of engine roughness and reaching peak EGT as signified by the relevant cylinder stack flashing seems like an arse puckering eternity. I am never so relieved to start screwing that mixture back in for 100f under peak EGT/best power. I have no concern when at high altitudes but when over built up areas or water I couldn't imagine leaving it to run at best economy with the engine giving the roughness it does.
Am I missing something here?
Note: the aircraft has just had its annual so everything is in theory set and running correctly
