Dual Dellorto carb setup, the carbs tend to snap under load. After tinkering for a while with airflow and linkage and not resolving, I am going to go to basics and check fuel pressure. How do I measure this? Is there an inline guage I can buy?

the cb pump he's running does not have a return line feature. internally regulated at 3.5#. unless the pump is defective i doubt it is the problem. could be a vaccume leak, linkage is out of adjustment (if the flow is the same when attached that shouldn't be it unless when the shafts are off the idle speed screws the linkage falls to a natural position). if just one side is making the racket it can indicate which side is wrong...that's why i asked at what specific rpm it's occuring. could be at the transition circuit. if thomas looks down a throat, checks against his paper work and supplies the vent size that should be of some help eliminating potential culprits. i'd turn the engine speed up with the one idle screw and see what the side to side flow rate is.
