I'm no Smokololigist and I'm sure this has been beaten to death, but here goes. I did a mailbox mod and everything works just fine. I have read many posts about the AMNPS not working at all. I started a brisket last night at midnight. I got 8.5 hours of smoke from the AMNPS. Great right? Long story, Dad and me had 16 foot wood fired pipe smoker. Smoke to the meat until you pulled it off. I am sure the 8.5 hours is great and not complaining, but I am looking for suggestions to extend to 10 or better. What are the benefits to closing the top exhaust off a little bit versus restricting the air input to the mailbox? First off, is there any real benefit for having smoke on the meat for more than 8.5 hours?
