Does anybody open their needle valve all the way on their hose regulator? The reason I ask is because I started my smoker this AM with a new Bayou Classic line w needle valve....I had the needle valve fully opened and you could hear the propane whooshing out. Being the idiot I am, I still lit the smoker and....KABOOM!!! Lol I shut her down and started it again with the needle valve open 1/4 to 1/2 turn. It's working fine now....but should I be hearing the afterburners kick on when I start opening up the valve fully?? I have a MB XL 40"
