Hello All, I bought a used Brinkmann vertical propane smoker, not sure model number but it looks just like the 810-5534-S and have been having several issues: 1) Meat I smoked is not getting very much smoke flavor and no smoke ring 2) Chips don't stay smoking throughout the process 3)meat isn't cooking to temp in time calculated or discussed in recipes 4) The smoke is exiting through the doors of the smoker(both bottom and top) instead of out of the top chimney I really want to get my smoking on point by summer time and I've tried fixing these issues, from firing up the smoker at full blast with the chip pan as close to the flame as possible- but when I bring the heat down to get in the sweet spot(I always try to keep between 200-250) the chips stop smoking. I did a bone-in pork shoulder that weighed 5-6lbs and smoked it at 225-250 for over 9hours and it still wasn't close to temp and when it was done it definitely wasn't "pulled pork" i had to cube it up. I've tried to seal the doors to keep the smoke from coming out of the doors but it seems like no matter what I do the smoke won't go up out the top chimney. Sorry for being long-winded, but I guess my question is--- should I keep trying to make this smoker work or should I just find a better one to start out with AND if so can you please recommend a specific vertical propane smoker that is easy to get started with and isn't too expensive(I'd love to keep it around $200 or less)? Do you think the used one I bought is just jacked up and that's why the guy sold it to me for cheap? Thank you very much for any advice!!!
