Has anyone had personal experience and success converting a Banjo Classic Burner from propane to natural gas? I know you have to change out the orifice, but this isn't something in stock at Depot, and Banjo has nothing I've sen on a website. The only thing I've seen is an orifice Blichman offers for the top tier system ... which I'm wondering if I can use on the Banjo. NG at 4 pounds of PSI isn't going to cut it unless I figure out a way to enlarge the orifice.
