1227747 Chevy 350 Datalog running rich

The attached datalog is for a 1968 Landcruiser with an older non TBI Chevy 350 (no EGR) and it is running rich. Is the reason the IAC position climbs to 140 because the ECU is trying to lean the mixture? What setting needs to be changed to keep it from going into open loop at idle? Is this enough data to begin making the VE changes?.

Attached is the ASDX modified bin I used and $42-1227747-V5.9.7.xdf and $42-1227747-V5.2.adx. The timing is set at 6*BTC and the "datalog off" 1-7 are all disabled. Am I missing anything?

I would lower the BPW down to 132 or 133 because overall closed loop data is rich. I'm thinking there are to many 108 BLM averages. My spreadsheet, see attached screen shot, filters for closed loop only.
