So I got my gas manifold finished and fired it up to check for leaks. No leaks but the flame is very weak. These are low pressure bg14's plumbed through a marshall 230 regulator into 1/2 black iron, with flex tubing running to the burners. Orifices are the lp ones from brewers hardware. The flame is only about 1/4" high when I open the valve wide open. Suggestions???? I know im not gonna get the kind of flame I'm used to with high pressure burners, but it has to be better than this
