Thank you for the input i have checked the jet and removed the burner and worked fine. My forge is made of brick 6.5"x6.5"x14" and i have a single burner i wouldn't think that the forge would be to small, the forge is open on both sides and i have bricks on either side to act as doors the the burner works fine with both doors open and as soon as i close one side it starts acting up and goes completely out if i shut both sides
