Just put my brisket on - used a mix of Cowboy lump and BGE lump. Pretty lively fire until I closed up the egg and reduced the dampers. Then something interesting happened - I opened the egg (slowly as always - 'burped' it first) to insert the temp probe, then closed it. When I closed it a blast of fire shot out of the lower damper. Looked like a jet engine for a second or so. Anyone ever seen that?
