So I just got my BGE and this is my first post. I have played with it, unfortunately, I'm struggling to get the temprature to hold under 300. I can get it to keep at 300 plus or minus 5 degrees, but can't get 250 or 275 for ribs or brisket. I'm using the electric starter and tried put only a few lumps over the ring. It slowly crept up, but once closed, it kept climbing. I had the vent nearly all the way closed and the vent on top nearly all closed. Any tips for getting a solid 225 or 250 temprature?
