Just wanted to confirm this is what I think it is....I usually burn at a 6 - 8 / 2-8-1. This keeps the fire really even and strong. Since the weather is warming up I have backed the feed down a bit. It seems like the flame has started to pulse from when the pellets drop into the burn pot. Is this because my settings are still at 2-8-1? I just switched it to a 4-4-1 to see if it made any difference. Does everyone need to adjust their air level and feed rate when backing down their temperatures?
