This morning for an experiment, I switched the idle circuit around, IFR .031, IAB .067, t slot restriction to .046, just to if there was much difference. Didn't appear to be much, highway cruising uses so little throttle that it seems like it is in the bottom of the t slot along with the idle adjustment and a little richer than I would prefer, someday maybe fix that.

The PVCR was reduced, originally .0595 was 12-1, .055 was 12.5, and .052 where I ended up at was 13-1. So each size drill bit was good for .5 on the afr gauge.
