Is the popping still only coming from one side or is it from both sides? Maybe your exhaust manifolds are secure and fine......on these carbs there is a small diaphragm for the enrichening circuit......it adds a extra amount of fuel to the cylinder when you let off the throttle to keep the ultra lean condition from happening. Maybe one or both of these small diaphragms are not working or damaged? I believe they can be checked without removing the carbs.
