I just built one of Ron Reil's mini atmosphere burners. I don't have a nozzle flare on it, but am using a 1" pipe nipple on a 3/4" burner shaft in the meantime as per the design suggestion. I tried lighting the burner with a propane torch and it won't stay lit unless i keep the flame on it. I tried increasing and reducing the gas pressure from 5-17psi with no success. If I turned the supply line off center then it would stay on, but not in a way where it was really burn-blowing, and it led to a flame up. Someone suggested that there was too much air coming in and someone else suggessted that the burner shaft wasn't slid deep into the nozzle enough. I haven't tried either of these suggestions yet, and was looking for some incite. The burner shaft is only stuck in the nozzle a little less than an inch. it's an 8" shaft with a 3" nozzle.
