Juan,

You DO have to be concerned about running too lean, which is
why Continental does not recommend leaning for extended periods of time at
high power settings (above 65%).


Ok, I'll try again. The point is to run at the right mixture setting. That
might be very rich of peak or lean of peak. Whichever you chose, "too lean"
is not the answer to "what's dangerous?".
