Baker's Pride Pizza Oven

I have a Baker’s Pride Pizza oven that I am trying to convert to propane to be used outdoors off of a propane tank. I changed the orifice and regulator but it still won’t light. It seems as though the gas doesn’t have enough pressure to make it all the way to the oven. Do I need a high pressure regulator? or no regulator at the unit just the standard propane tank regulator? Any suggestions would be greatly appreciated as I am driving my wife crazy with this!!!
