Dave - a non-op AAR will result in a richer mixture for the reasons I gave and Scott supported. A low CHT will make the mixture quite rich, and the lack of air from the AAR will make it more so. Same amt of gas + less air = more rich.
The benefit for pumping more oil seems sound, as does not having to dink with the throttle or have it stall when you stop for a light, etc., until it's completely warmed up. I've had plenty of cars you have to piss around with while they were warming up, but for a little time to repair or money to buy used, why bother?
As far as not having to make the AAR "air tight" when you put it back together, I'm pretty sure a leak on the manifold side of the valve would be a bad thing.
