UBA SU Carb from 1935 Morris 8 Completely Reconditioned

Just finished this very unusual 1″ UBA SU carb from a 1935 Morris 8 wedding car.

It was corroded, worn out and dirty, but as it was still giving faithful service at 83 years old, we decided to be nice and make it work properly and be beautiful again, while preserving the all important patina.

We were given the job just a few days before the car for was needed for the owners’ wedding so we were under a little pressure!

Here is to another 83 years happy motoring.
