What is "too lean?"

The only mixture that is "too lean" is one that will not burn--that's WAY LOP--and called Idle Cutoff.

If one is "not rich enough" on the rich side of peak EGT, the CHTs and ICPs can be dangerously high. I'm thinking that's what you meant. Right? Not too lean, but "not rich enough."

As for the engine monitor... it's clearly the most important engine management tool you can have. It will pay for itself many times over in reduced maintenance costs and can save your tail, too. They tend to pay for themselves "all at once!"
