And Gordon quoth from the Book of Rising Sun Racing, Emission Controls Chapter,
saying:
"On 1600's at the end of the production run there is a solenoid valve mounted on
the intake manifold that is controlled by switches on the clutch pedal and
gearbox. This by-pass valve is activated only when the car is in 3rd or 4th gear
with the clutch engaged (pedal released). The valve allows extra air into the
intake manifold during higher speed running (as in 3rd or 4th gear) to cause a
leaner mixture. The valve is connected to two tubes on the bottom of each
carburetor that draw air from the the throttle bore immediately in upstream of
the throttle valve."

It is part of the emission controls on the 70 1600 (I don't think that the
2000 got it). It is a Gulp or Backfire valve. I don't have the manual in
front of me now, so I can't explain how it works. One of our esteemed
gearheads will have to do that!
(Sorry Mike, not an electric Turbo!!)
