Try plugging off the bypass valve to see of this brings down the idle. If it
does, then the diaphragm in the bypass valve needs replaced. Do it to the
front carb, and then the rear carb.

Subject: [TR] 1972 TR6 Overzealous At Idle
Good day all,
My 1972 TR6 is stock, aside from a Pertronix Ignitor ignition module and a
Flamethrower coil. The car runs pretty good, aside from being terribly
cold-blooded and the idle speed is very high. The idle speed was just as
high before the Pertronix parts were added. It had a Crane ignition before.
The idle remains very high even with the choke cable disconnected, the
throttle linkage removed and the idle speed screws on both carbs backed out
to where the venturi are closed. The carb linkage moves freely and is not
binding.
Disconnecting the vacuum advance causes the RPMs to decrease only very
slightly.
Any thoughts?
Jerry
