Is anyone in this group interested in or experimenting with Lean of

operation? I'm especially interested in the experience of anyone
doing it
with a fixed pitch carb engine with single EGT and CHT probes.

I don't have exactly that setup, but pretty close. I've got an O-360
A2A with an Ellison throttle body carb on my COZY MKIV, with four
EGT/CHT's. I've started trying to run LOP lately, but only under 75%
power. I generally find that I can get to 50 degrees LOP or so on the
hottest cylinder (haven't checked all four cylinders all the time yet -
I've got a manual rotary switch - maybe on the way to S&F tomorrow from
MA I'll have some time to play with it). If I try to lean it out more
than that, it starts running pretty rough, I get uncomfortable, and the
canard shakes.

Now, I DON'T have a fuel flow gauge, so I really don't know what effect
this is having, other than slowing me down a few mph. I've just been
playing with it to see what happens.
