[6pack] 6pack Digest, Vol 88, Issue 2

[Robert Perry]

Luis,

Built June 1972 during a transition period.  The small tube at the top of the charcoal canister comes from the fuel tank vent to capture and burn the fumes through the vacuum of the engine.

Regards,
Robert

I believe those are 73+ carbs if they have the float vent tubes and valves.

Take a look at TRF or Moss diagrams in their online catalogs. They are in the emission section.

> 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.? ?
