Thanks for the information. I went ahead and adjusted the distributor about a 1/4 turn counter clockwise and this stopped the fire in the carb. Mine maybe running rich too. I now got some smoke out of the tail pipes. I am hoping this is just condensation because it has been raining while I've been working on it. It is white smoke but it's coming out of both tail pipes so I think my head gaskets are good.
