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.

The 1905 AVS2 should be a mechanical choke? Do you have a cable controlling it? IF you have a drop base air cleaner and too short of an air filter this could prevent the choke from opening all the way. It might also impede the secondary air door? Fro the image below it might not be likely.
