New, but been smokin' for 6 months. Have a Masterbuilt elec ANALOG. I can't get it to burn wood chips enough. I nuke the chips, and they still hardly burn at all in a 3 hr smoke. I drilled 2 -3/4" vent holes top & bott of cabinet to up the air flo. Also drilled 4- 1/4' holes in the chip pan. How can I increase the chip burning? I also have a Char Broil gas smoker that works fine. Also, are door thermos at all accurate? What;s a good 2 probe model; 1 for interior temp; and 1 for meat temp?
