Detonation caused by lean mixture
I've been studying for my aircraft tech ground exam and reading about the hazards of over-leaning the mixture. It brings to mind a time when I did a solo flight and managed to taxi to the holding point and do power checks with lean mixture, right up to the point where the checklist told me to check 'Mixture Rich'. I had noticed it seemed to be rough running, and of course increasing to full rich sorted that out. Now I've read about the theory, I'm wondering if I did damage to the engine. How would one know?
Shows the power of using checklists, but I wouldn't like to think I've damaged the engine.
