It idles very nicely, so I am guessing the pilot screw is pretty good. Maybe, I will need to invest in a carb syncer to see if they are off a little.

More than just idle quality, the pilot screw regulates carb performance throughout the pilot circuit, including tuning for a strong smooth pull-away from idle.
Same for sync.
Would suspect that pilot circuit is either too rich or too lean, either of which could contribute to poor performance at pull-away from idle.
Of course, there are many possible conditions that might result in the reported issue, such as noted in the FSM:

If so, any such popping may indicate a too lean pilot circuit.
