Went lean...

The PCV valve and the breather (on top of the valve cover) looks the same as original equipment.

Overall - It just plain ole seems like I must have had something put together wrong with the air cleaner and housing the last time I put it on. And I got it straight at this event. I say that because, there's just no logical way that I couldn't get the WOT lean enough, unless something was restricting the air flow. I must have snarkled something up somehow when putting on the air cleaner the time before this event.

It doesn't seem possible, but could I have had the choke jammed partially closed with the air cleaner housing? That would certainly restrict airflow. Matter of fact, the choke has been a PITA since this new carb. I'll tear it apart again and see if there could have been some way I was stopping the choke from being returned completely open.
