Hi,

in this first week of driving I seem to be shaking out every problem. Now it is my twin SU's. The idle speed is fine when I first start up and drive around in 1st and 2nd. However, if I jump on the highway or take it up to 60, the idle does not return to the lowest revs. I will gear down, come up to a light, push in the clutch and the engine is still reving away. If I pop the gas pedal the revs go up but return to the high setting. Only thing that stops it is if I drive for awhile or stop the car and restart it.

Now my gas mileage is also terrible but it could be from the above problem.

Any idea what this is? Is there a fast idle adjustment screw, and if there is, does it change both carbs or do I have to do them separately?

Apart from lots of minor warts the car seems great and certainly turns alot of heads.
