With the Masterbuilt you can pull out the loader and check the wood. It seems like the element actually lights the wood chunks at the beginning then they burn like charcoal later on, very little visible smoke, lots of good flavor.
Thus at first a lot of visible smoke, later very little. The later time is the best for the food though. I switched from chips to chunks, loads more of the later type smoke.
If you're getting smoke at first then little, sounds like things are going fine.
