Question: has any one of you experienced the Vent control wheel not working after smoking for 6+ hours? I smoked my pulled pork last week and i tried to close the vent since I was done with the pork and wanted to kill the fire. But instead of spinning, the little lever just bends. I think I have it a little tighter than necessary so I'm going to loosen it before I Q tomorrow but I just thought it was strange that it wasn't able to handle the heat. I have an extra vent wheel since I got one from both the super pro and the firebox. But just thought I'd ask and see what others are experiencing.
