ILBob... I fired it up on unleaded just to make sure it worked OK...it is a backup to the propane dual burner camp stove... drained it well and relit it to burn out as much of the fuel as possible...put it back in the box, and hope I'll never have to use it...I bought a kero radiant heater, so have a 5gal supply of #1 on hand for it and the Dietz lamps...hard to find bulk kero where I live...
