I had problems about a year ago with my flame. Folks here suggested shutting everything down, disconnecting the regulator, and starting from scratch. I had been happy with my flame and output, so I had stopped turning down my regulator. Apparently there is a default with regulators that they need to be shut off as well, or they go into a sort of safe mode, where the output is drastically reduced. Once I shut everything off, and started over, no more problems. Might help, might not be your problem, but give it a try
