I, too, have trouble getting my Masterbuilt Pro smoker down to low temps. I ordered the Bayou Classic needle valve to install on the regulator coming off of the propane tank. When I went to unscrew the hose from the regulator, I find that there is no hex surface to clamp on to to unscrew the hose. It appears that the hose & the regulator are one together. Someone told me that that is called a pivotal connection so that the hose won't get in a bind if the regulator has to be turned at an odd angle. I'm not sure about that. The hose on my Char-Broil Big E-Z has a nut-like base to put a wrench on to unscrew it from the regulator.
Does anyone know how to get the hose off of the regulator? Or am I going to have to go out & purchase a whole new regulator/hose? I am assuming that it is best to put the needle valve coming out of the regulator & not where the hose is connected to the burner on the bottom of the smoker. That would be a real pain to deal with.
