Ok, I'm not familiar with this model but I'm thinking it's a horizontal? Since the meat at the firebox/smoke chamber hole got done I'm thinking you may need a baffle or some sort of tuning plate to more evenly disperse the heat throughout the chamber. In our files section there's a folder named Mods. Check there about horizontals. I know some need to have the chimney lowered more into the chamber which will help keep smoke in and not just exit straight out. Tuning plates, etc are all covered there. I'm sure someone with a horizontal will chime in soon, if they haven't already by the time I submit this.
Sorry I couldn't help more.
I didn't hijack the thread. I just took it in a completely different direction.
