Thought I'd post this here in case anyone is thinking of having their carby rebuilt or reconditioned...
I've just had my 1 1/4" SU Carby rebuilt for my '64 Mini by a crew called SU Midel. I had read about these guys in Australian Classic Car Mag (years ago when I used to buy it regularly) and thought I'd give them a go. Boxed it up and posted it to them, and it came back like this (!!!!):
All parts bead blasted to give the factory appearance, alloy housing polished, ferrous parts nickel plated. Throttle shaft bushings removed and replaced with new, new throttle shaft (i.e. NO MORE THROTTLE SHAFT PLAY!!!!). All new fasteners, completely rebuilt using new seals, needle, jet etc etc. I am absolutely over the moon with the result! The whole thing cost me just under $280 all up - which I think was well worth it considering the end result and the attention to detail (better than new!) - most carby places would charge around $100-150 just to put a kit through or replace the jet/needle/seals etc.
Whilst they are SU specialists they say they will do any other make of carby too - this is their website:

Now I just have to find someone who knows how to tune it once it's on the car.... (thankfully I'm not running triple SU's!).
Hope this helps!
