Well, the idle is quite low, about 700 rpm.
The question about enrichment was only to know what was done to the car, and to gain performance, but want to be sure at what cost.
Henryk, about the idle adjustment, I believed that it was a screw in the left of the, just under the airbox, but it is only present in early models. No screw in my car, unless you are talking about other screw. Can you confirm this, please?

Another thing: I have noticed that my idle is a bit more rough and low after having changed my air filter and distributor rotor. Is this normal until it wears a little bit? (I haven't changed the distributor cap as it seemed ok)

Thanks.
