I can't find any thread on the forum of anyone with the same smoker as I have. It's model 20070612. The only hole it has is a tiny dime-sized one on the back. This prevents any airflow, causing my AMNPS to never stay lit. Anybody have any ideas on what I can do? I basically have a meat roaster at this point, since it can't actually smoke anything. Should I try drilling holes? How and where would I do that? I paid $50 for this smoker. Would it even be worth it to do that kind of mod on this model?
