Jimmyjack, I'd get the proven burners talked about on this site. However the 82MJ would be fine also as I think that is just the two ring version of the 55Mj burner. Not sure about the LP one, but the figures say it will work of course but it's up to you. You'll miss out on the ROAR effect with a LP burner :super:
From Gameco or Auscrown the part number is RH13LT (55mj/hr), Regulator is part number 6060902 plus 970U for the POL fitting, and the hose to suit is part number 1222/2000 which is two metres long. I was quoted $126 delivered to Hobart for the lot.
Allstart, you definitely have the wrong Wok burner as the guys have alluded to above. The wok burner I'm talking about above is well proven by the other members here on the site. I'm guessing you have a different model or are running the wok burner I'm talking about on a low pressure reg or something.
Anyway, good luck Jimmyjack. They are a cool toy.
Cheers, Justin
