Mistimed Mags?
One of our engines is running near 400 degrees on the ground with the power at idle. The mixture is leaned. We have replaced the CHT probe (only one) but have not touched the gauge itself. Our mechanic mentioned the possibility of having some mistimed mags which could drive the temperature up. But near 400? I don't believe that.
We have run the engine with the cowling off and shot it with a laser temp. gun with no cylinder showing above 275 on the ground. Could it just be a bad gauge in the cockpit?
