I was using my Big Block yesterday and could not get the temps to go above 180. I had plenty of gas in the tank. I reset the regulator by disconnecting, etc. It improved for a while but noticed when I adjusted the control know the flame would get real long and lanky... If I shook the tank, the flame would turn back to a nice yellow with small blue tip. Every time I adjust temps, the flame would get all out of whack. I then started tapping the regulator on occasion and presto, the flame would once again become as it should. Would you guess that my regulator is going bad and needs replaced? Is there a difference between a regulator for a gas grill and one for a gas smoker?
