I have found several times now that it's common when the flame is weak or doesn't go all the way around the burner or it takes a bit for it to go all the way around. The stock regulators on these are going bad. Nothing to do with the burner. It is definitely the weak point of the Q series grills. They are so commonly bad or going bad that I just do a regulator delete and use a proper regulator hose that will actually last. Plus they perform better that way anyway.
