That hole off center could be a restriction causing a stumble possibly.
Did it run good at first after cleaning the needle and seat and resetting the floats? I'm thinking you might have more junk in them coming farther upstream in your fuel system. Just a thought.
I was eventually able to get the stumble out with bigger accelerator pump cams, but that's when the loading up and stalling began. Holley keeps telling me to put a vacuum gauge on the car at idle and select a power valve 1/2 of the vacuum I see, however the car idled and drove fine with the current 6.5 power valve until last week. Im really dumbfounded on this....
