Ok, not to start the age old debate again, but I am interrested in hearing what the "collective" is doing out there for leaning aircraft engines. I fly an aircraft with an IO-360 A series fuel injected lycoming and curious as to the accepted real world procedure out there. I have read all of the info that Lycoming has to offer on their website. One of the aircraft that I fly recently had to replace the exhaust due to deformed baffles inside. Is leaning the cause?
Your Thoughts everyone...

It shows I would have to be 250° rich of peak or higher, in order to run safely,? Is that not right. According to the graph?
If I was to operate my plane that way, I would burn a whole bunch more gas, and I would definitely screw up my sparkplugs. Not to mention, I probably would not have the power to get off my runway.
I have an electronics international single probe EGT and usually dial it in to about 50° rich, the EGT is really nice, because once you figure out what temperature your engine runs at during the various times of the year at the different elevations you run at you can pretty much dial-in or out as you climb and descend and keep it perfect,
But, if you're not a gadget freak, running it rough. And then bumping in the mixture just past where it smooths out has always worked well . just remember to check it whenever you're flying conditions change,"altitude and/or temperature"

B.) I find it fascinating that no one trusts their fuel gauge beyond saying "ya...it might have gas", no one I know has a tach that reads within 50 RPM of what the real RPM is, oil pressure gauges are notorious for being a "in the green or not" instrument, and yet after all that, we are trusting EGT / CHT instruments down to the gnats ass ?
