Hi Guys,
Today, While cruising at 5500' and 5000rpm, the EGT was reading around 1675.   Then about two hours into the flight, there was a slight loss of power to around 4800rpm, but the EGT shot up to 1800 where I have the limit light set.  I had the mixture set with 0-1 bar showing in the mixture meter.  To lower the EGT, I made the mixture richer to 5-6 bars. and the temp came down but stayed around 1750 for the rest of the day.   Any guesses?
Thanks in advance!

Sounds like you went lean for some reason. Pump,filter,debris in injector screens - many things to look at. Another distant possibilty would be that your timing has retarded from nominal.
