I used to do a lot of smoker but got away from it and my son gave me this smoker for Christmas. I use it on Sunday and did a Turkey. It came out very good but I had to finish it in the oven. I was unable to get the temp up on the smoker over 150. What do I need to do to get the temp up. Would it be better to get some wood and use that over charcoal? I looking forward to using it a lot like I use to. Thanks for any infromation
