I've always got about 20 in town and 30 on highway trips with my MGBs, with no overdrive. Got about 32 once with the roadster on a trip, and have sometimes dropped to 18 or so when the trips were short and the weather cold.

I can't understand why people are frightened of new ideas. I'm frightened of the old ones. John Cage

MkI - Overdrive - Supercharger;

Regularly get 25mpg - took a few tries to get the mixture and timing right
but now is perfect. Plugs are a nice malty colour, engine has good torque/power.

You may want to try an O2 sensor and a good gauge to tune the mixture.
