Default Carb Backfire

Gang.

Was returning from an afternoon ride and was accelerating hard through second gear when there was a loud pop through the engine(backfire versus mechanical break). The engine would continue to run, but with popping through the carbuerator. Pulled over and gave a visual on the plug wires, distributor, and wires. Guages read steady in operation. Removed the air cleaner and started the engine. Popping appeared to be backfire through the carb, with spark visual in carb. Jets on one side seem to flow gas in a retarded manner, while the other side seems to mist. Have a Holley 650cfm, on my 351w. Does anyone have an idea if this sounds like carbueration, or am I possibly not firing in one of the cylinders, or something other?

Fred
