I'm betting a float/needle seat issue. 1) how do you know the spec height number you are using is correct for this application? 2) even if set correctly the needle seat can be slightly bad and cause flooding over. The primary rods properly in or stuck out in enrichment mode should not matter at base idle. Are you sure your float is not gas logged?

Early on the float stuck down and flooded over big time, gas flowing out the vent tube and puddling on top of the engine, I rebuilt the carb put in new needle and seat and float and it seemed to be better no more flooding over, I think it was drawing fuel from the primaries at idle after the rebuild, I hadn't even looked at it before the great flood. After the rebuild is when I found the water in the gas tanks so I drained and flushed them, added a 12 micron water separator/fuel filter and used it for the summer last year, a few short trips. This last winter I pulled the tanks and rebuilt the whole fuel system.

I'm going to order another kit for it and see if the needle and seat may have been the culprit, I disassembled it today and they look new, nothing looks out of place or bad so far.
