Hi Chris this is a great idea!! a lot simpler , you dont need a really powerful blower to get the gas to the front after it has been flared here is a link to what Paul Halvorson did to move the gas to the front, to start on woodgas
you will need to scroll down to reply#344 he has some photos and tells how he did the add on.
I dont know if I am brave enough to give up gasoline altogether either but it is a good idea though
