Thanks for the responses.
I did that one too. I found that a soup can fit perfectly inside the smoke stack. I have it about an inch from the grate.
One thing, I am measuring the temp at either end by having put themometers through in either corner of the chamber door. I may have them too far apart, meaning measuring at the extreme ends of the grill. Just a thought. Maybe I should do the whitebread test instead.
All that you bring into the lives of others will come back to you in your own. Good or Bad.
