Hi guys,
I've been trying to figure this out for just over a month at this point to absolutely no avail. I recently built a new forge after I decided relining my Devil Forge wasn't going to work, and reused the Venturi burners from that. When I removed the burners, I noticed the flare on the burner I used most was crumbling and blown out, so I initially tried to remake my own based off the ones they had on there. When I installed them into the new forge, they ran perfectly for the first 10-15 minutes until it got up to heat, then started fluttering. The flame was still going, but it was burning way less efficiently than I was used to in the Devil Forge. It would jump back and forth between a nice roaring blue cone and a much quieter teal flame. After ruling out a failing regulator, debris in the hose/connections, airflow issues, and basically anything else I could think of, I swapped the homemade flares for some of the ones Larry Zoeller makes, and now I'm not even getting the blue cone. I'm at my absolute wit's (and wallet's) end with this. I didn't think to get better pictures of the current setup, but I got a video of what was going on before swapping over to some properly made flares. What's happening now is similar to what you see in 90% of the video, minus the fluttering sound. Any help at this point will be greatly appreciated.
