All, Thanks for the help with this, I'm sure everyone will give me some great advice. I've purchased a CGSP this summer and need help keeping my fire in the 220-250 range. I've made some modifications (and I'm stealing images from caiguar to help show these). Basic info: 1. The football shaped piece has been removed. 2. I've installed the pipe to the grill grates like this 3. I'm using this for my charcoal basket, but have installed two bolts through the side of the firebox to brace it, with the bottom bolt in the foootball shaped hole to also brace the basket. 4. I've take the main chamber charcoal basket and flipped it as the baffle. Additionally, 6 inches from the fire box, I've drilled 4 1/2" holes every 4 inches to allow hot air up towards the grill and increase airflow. This weekend I smoked a pork shoulder, a slab of ribs and some ABT's. I used a mix of Lump and Briquettes. First fire was a lit chimney of briquettes on top of lump. I had the smoke stack open wide and the air vent on the fire box all the way open (and was all day). Fire got the smoker into the 210-220 range, added some unlit briquettes on top, smoking wood, and put the pork shoulder on the grill. I ran an errand and came back to 230 an hour later. Throughout the day I added 1/2 a chimney to a full chimney of lit briquette or lump, plus wood as necessary. This was approximately every hour, but the fire would not get back into the 230's. I stayed low 200's, with the last 1 1/2 - 2 hours in the 190's. The briquettes & lump would never seem to want to burn, it was more of a slow smoulder (even the wood wouldn't fully burn). That's the basics. Any thoughts? I'm sure there are questions, so I'll work to answer them, as I'd love some suggestions.
