I made this video awhile back, but after reading CrazyDoug's post asking for Flame Licker examples...I wanted to show this one running very well. It took me some experimentation to get this running repeatedly, but it's there now with the only issue being it blows it's own flame out frequently, something I can't resolve other than relighting the little tea kettle like burner.
Here is the YouTube video showing these can and do run well...usually!!!
