Well, after being on here a coupla weeks and soaking up the great info I decided to drag the old ECB outta the garage and clean it up. Did the recommended mods...drilled air holes, sand in the water pan, chicken wire basket for the coals etc. Got a longggg probe therm in a tater on top of the grill, bought a digital therm & have that in a tater as well on the grill to double check temps and put a dial therm from a grill above the useless ECB therm. Started with a 2/3 full chimney of hot coals and checking temps every 15 minutes. The probe was spot on in a boiling water test at 212...forgot to write down the digital test but I remember it was off a little low. First check the probe was 310, the digital 290. 2nd check probe was 300, digital 270. 3rd check probe was 275, digital was 267. Grill therm hasn't moved much...190 down from 200. Last check probe at 250, digital at 242 and grill therm at 175. Coals looking like I should add a few more at this point to keep things where they are. So I'm thinking when going to do a load I should add meat about this point? along with a few coals? since the temps seemed to have evened out after some initial flucuations. Words of wisdom appreciated...have a chuckie in the fridge I'd like to do in a few days. Oh, very windy here today, hence the windbreak
