August 9, 20178 yr Hello, Without an EGT gauge, and without any audio feedback of a rougher running engine, I was wondering how you Milviz Beaver pilots get just the right fuel/air mixture. Leaning my mixture does result in a power change, too lean causes my speeds to slow, but the engine sounds exactly the same. And if I lean too much, the engine will start to cut out, so I know when I am way too lean. But I don't want to lean THAT much. I only want to lean to peak EGT, from after which more leaning will cause the engine to begin to run poorly. How do you guys find just the right mixture? Daniel Moser
August 9, 20178 yr Daniel, The way I learned without an EGT gauge is 1) lean until noticeable roughness of the engine 2) enrich until engine smooth 3) continue to enrich about the same amount that it took from rough to smooth. In the sim, this may or may not work depending on how the sim aircraft is coded. As a proxy for EGT (in the sim only), you can use RPM to get close too. Some sim aircraft with appropriate gauges (pointing my finger at you Carenado) don't lean correctly even with the EGT. Hope this helps My MSFS 2020 repaints: Flightsim.to - Profile of HStreet Working on MSFS 2024 versions.
August 9, 20178 yr Does it have a fuel flow gauge? You could lean until you get maximum fuel flow and then reduce a bit until fuel flow just barely starts to drop. (Or leave at max. fuel flow for maximum performance)

There's a topic on Milviz Support forum telling how to do so. Title is "Throttle, RPM & Mixture Adjustments and Reaction" Tom
