Hi All I'm new at this. Have the weber smokey mtn 18". I'm using it right now for the second time. Have a 7 lb pork shoulder picnic going. I filled the chimney. Poured it in about 20 min later. Put in 4 chunks of hickory that I soaked about 30 min. added another 50 or so briquests. Kingsford original. Had a lot of smoke at first, but by about an hour in, there was no smoke coming out the top vent which is open about 1/2 way. Its been on almost 2 hours now, has held fairly steady at 240F (trying to get that down about 10 degrees) Is this normal? Haven't peaked in at all since if started it this morning. My first smoke was a 12 lb turkey with applewood. It came out with good flavor but kinda dry. I didn't brine it but I think next time I will.
