I am currently chasing a poor vacuum issue, and along my path am into the bypass valves on the carbs.
1976 TR6 Vac retard.
I am a bit confused as the gasket that mounts the bypass valve to the carburetor has a section missing between the two ports?
I understand that:
There is a signal port (the tiny one), A port on the manifold side of the throttle plate, and a port on the Carb side of the plate. When the manifold depression exceeds the setting the valve floats and allows more air from the carb to the manifold side...
I seem to have old gaskets that have the bridge between the two larger ports, yet I also seem to have some without, which makes no sense to me as there would be a constant leak across this gap.
(In looking at the Moss Kit, it seems to provide both?)
Does anybody have any insight?
