I removed the vent entirely and added a elbow. I have tried every different 1/2 inch variance with the chip loader. I stopped using water entirely with my smokes. I put the amps on the drip tray above the hole cut for the drip catcher and put the drip catcher on the floor. I always get a good burn going on the pellets to the point where it is hard to blow them out. I never had these problems with my gen1!!!! I am at the point where i just want to go buy a gas smoker and be done with the MES line entirely. What am i doing wrong? Is the mailbox mod going to save me or just be another money sink?
