I have a offset smoker that was built by hand that I purchased from a neighbor. It's my first smoker. I have used it about 5 times now and can never get the heat above 200 without putting charcoal directly in the cooking chamber. The fire box had no ventilation or dampers so I drilled a few holes to create some air flow hoping that would help get the temp to rise. I haven't seen any jump because of that. I'm a little stumped as to how to get the temp up to somewhere in the 270 degree range. You can see a pic of my smoker on my profile pic. I am using charcoal as my fuel. Should I be using wood as well? Thanks for any advice.
