Reading forums and surfing the web over the last week a couple of things that come to light which may be adding to our problem is: 1. The water bowl may be too close to the coals because I can't get a good thick layer of coals on the tray. 2. Also because of this the water tray is preventing the heat from the coals reaching the chicken. 3. The water boils too much thus suppressing the heat from reaching the chicken. 4. I also tend to keep the vents closed too much thinking I will let all the heat out. Well that's my limited take on it anyway.
Well that's me, I have a couple of responses to digest and reply to and look forward to communicating with everyone via the forum and learning a lot about smoking.
