@Kennyd4110, I don't have much data to support my claim that the restrictors have limited the ability of the chute rotation motor to break any ice bonds, it's just my intuition and this morning's experience. I hope you don't take it as criticism of your restrictors. It's not intended to be, and I should state that I could be wrong about the effect of the restrictors in terms of less flow or flux. There are lots of variables and I'm here to learn and expand my knowledge base as much as anyone. As more data or information becomes available I might have to modify my assumptions.
