I am having major trouble with this new retro kit. I installed it. Now when I use the smoker I am getting so much smoke and it back fires, puffs major dirty smoke. I load this the same way I did before I installed the new retro kit. Is anyone else out there having the same issues? What am I doing wrong. I used to get the thin blue smoke before this new retro kit, not it looks like Im burning the town down. Any help or suggestions are appreciated.
