I just bought this factory Honda vacuum gauge set off Ebay.
Not sure why they have adjustable valves on them other than possibly closing off individual gauges for 2 or 3 cylinder engines maybe?
Are the valves really necessary for synchronization of carbs?
All the other sets I seen do not have them.
