expected MPG on 2 + 2

Hi All,
I was wondering what MPG you are seeing on average when driving your elan? I have a 2 + 2 (S130) with a 4 speed box on twin dellorto 40's. I am burning what I think is an insane amount of fuel. I have recently had the carbs off to try and solve it. I have cleaned them, replaced the o-rings each side of the thackery washers, checked the float level and checked everything else is ok. I then re-tuned it (to the best of my ability) It now runs a lot better, accelerates smoother etc, BUT, i have not acheived better economy at all!
The only other point to mention is that years back I have the car tuned on a rolling road, and the man who did it replaced the standard jets, but having said that it is still running on the standard air filter etc, so i cant see that making much difference.
Now for the figures, well here in the UK, I fill my tank up with say approx ?50 worth of fuel for a full tank. (difficult to tell when its totally full due to the bad nature of how the tank fills) and on a whole tank of unleaded I can just about get 230 miles. My rough calcualtions equate to about 20-22 MPG on my car! This to me is crazy. Im a fairly average driver and dont thrash it too much, I met a fellow plus two owner the other day who recons he can get 40 MPG out of his!!!!
Finally to answer all queries it is also on electronic ignition. So of anyone can let me know what MPG they get from their car, and how many (roughly) miles out of a tank I would be very interested, plus what they think may be my problem.
Many thanks in advance
Simon
