Hey my friend I have one of those little fellas, I use Lazzari mesquite with cherry or pecan chunks ( soaked for 1/2 hr. before smoking starts. I drilled three 1/2 holes in the bottom of the fire pan for ash and air flow, fill your water pan only 3/4 from the top and line with foil ( boil over and easier to clean. Put the meat on the top grate, I have put two 8 lbs. shoulders at the same time, just leave a little space between the meat for smoke. Do not I MEAN DO NOT remove the lid if at all possible, I cook them for 10 to 11 hrs and then lift the lid check the temp. When your shoulders are at 165 to 170 I remove wrap and in foil with a little apple juice between the meat and foil wrap twice put in the oven until internal temp is 200 to 205, fall off the bone (smack your mama) just a pun in the mouth taste. I have done this way and am ready to leave on for 15 to 16 hrs for full cooking next. Hope this helps, happy smoking
