Is your engine a basically stock 907... ie, 2.0 Litres? The 911 is a 2.2 Litre, and carbs jetted properly for a 911 will probably be too rich for a smaller, 2.0 Litre 907.
This I don't know for sure. Based on the low mileage (40,000 mile), and the generally basic nature of the engine, (stock ignition, stock exhaust) I'm going to assume stock, but of course there is the chance it's been warmed over.

That's not good. The Idle Mixture Screws should end up about 3 1/2 to 3 3/4 turns out. Less than that (and fully seated IS LESS than that) indicates the Idle Circuit is too rich, and you're trying to compensate by adjusting the Idle Mixture Screws too lean.
Yes, I'm going to lean this circuit out as a first step.
Thanks for your replies.
