The forestry service here uses a mix of gas and diesel, don't know what the mix is. Then they put it in a heavy iron pot with a screw on lid. There is a piece of 1/4" pipe welded to the lid with a loop bent in the middle. In the end is a piece of rag twisted into it. You pour some mix out so the rag is soaked and light the rag on fire. Then you just pour out burning mix and it drips out fire. Works well, just walk along and leave a trail of fire behind you.
BTW the spring no burn season has started here.
