Weber experts needed.

I recently rebuilt my 40IDA's and am having some issues.

During the rebuild I drilled out all of the lead balls used to plug cross drillings (3 on the front with the jets, 3 on the top of the main body one from each set plugging the same pair of intersecting passages) and re-plugged with fresh balls.

(I have used web images and tried to indicate the location of one of each three balls below - lower arrow may not be pointing correctly as I cannot see the ball in this view)

I now have an issue where it misses on #2 a lot and I think the loud inlet popping is also coming from that cylinder. That is also associated with the specific lead balls I am concerned with.

If, in the drilling and re-plugging of this particular circuit in the center of this carb I either partially blocked this circuit or air is leaking in past the balls would it cause this?

Thanks
