A friend has a 1971 TR6 CC54624, manufactured Oct 70.
The distributor has both vacuum advance and vacuum retard units.
The port on the top of the front carb that normally goes to the vacuum advance
is plugged. (The PO had connected the vacuum advance and retard units to the
breathing ports on the side of the carbs)
The page 511 (86.35.00 sheet 1) of the Bentley manual says that the vacuum
advance for US engines was disabled by sealing the pipe with a protective
plug. As I read this, the vacuum advance unit should still be on the carb but
no hose connected.
Can anyone confirm the above.
