I bought a small BGE about a month ago to with my Large. I am having problems getting temperatures above 300. I have just cleaned it out and will fill with new lump and give her another try. I have the air hole in the fire box in line with the bottom vent the grate has the bevel holes down. Last night I had the daisy wheel off and the bottom vent all the way open and the best I could do was 350. Any suggestions????
