I finally had time to revisit this problem after a nice long vacation. I replaced both needles and seats with no luck. Then I decided to swap out the fuel pressure regulator with a new one. The old one was the dial type And the dial felt loose. After replacing the pressure regulator the problem persisted, so that wasnt it. Im not sure what else to look at other than replacing the floats. But they are the non adjustable type and look ok. Could the power valve be blown? Im not sure what else would allow fuel to flood the carb and find its way down the exhaust.

Truckster - I do have an in-line filter, the clear type right before the carb after the pressure regulator.
