Hi all. iv been reading some threads about not getting enough smoke from some pellet smokers. I am new too pellet smoking. I have a yoder ys640 on the way along with . A 12" amazing smoker tube. My question is why cant you just close the top vent a littlecto get more smoke flavor? You still get the air flow if you close it up a bit dont you or do you have too run the pellet smokers wide open vent. thanks for any information.
