[6pack] 73 emissions question

[Yahoo]

Hi all    just went back to ZS carbs after 20 years with hs6.   I had a decent set of ZS on the shelf so used them rather then rebuilding hs6    Looking at the carbs from the passenger side of the car, the metal tubes that go straight out to the left are vented to air.   Should the metal tubes on the right side that go up at a 45 degree angle be capped or vented to air? I ran the vacuum line from retard capsule over to bottom of carb.  The rocker cover vent tube vents to air outside the engine bay.  No emissions test or inspection in my sparsely populated province.   Thank you, Bruce Simms
