Nope, just trying to keep from going broke driving to work. I'm actually
going to raise the AFR some more until I can make it have lean misfires,
then
I'll know the limits. Unless there is an upper clipping limit on the AFR
like
there may be with spark advance, I'll find it. I figure blowing my engine is
the least I can do for the good of the list. JW>>

JW,

I found a graph in a book that shows performance variations compared to AFR.
At constant speed and constant spark timing (minimum best timing), BSFC
drops as AFR is increased up to a point (best economy) at about 17.6. After
that point BSFC begins to rise again and torque continues to drop.
