Tony's list is very helpful as while I've played quite a lot with other vehicles, Austin 7s are still bit of unknown territory.
I change to top at around 27mph because that sounds like the point at which the engine is at its max output and it will hardly reach 30 on the flat no matter how hard I push the gas pedal.
The carb is mounted on a tall(ish) vertical inlet tract which I would have expected to give a good flow. My previous car had a horizontal inlet which was changed to take the downdraught SU. I should have kept that carb/tract when I sold the car, doh!
I'll have a further play with the thing this afternoon...
