I gotta stand up and represent for the incorrectly-maligned SUs.  Mine on my last MG were set-and-forget reliable once the worn bushings (causing air leaks) were replaced.  They probably have a lower performance ceiling than Webers, but they're simple as an anvil, easy to tune, and they don't have tiny little passages or jets that get clogged.

Me too, Lane.  I had a series of LBCs (Little British Cars), mainly MGs, and never had an issue with SU carbs.  They were a lot better than the Strombergs on the TR6.

Me three.

I currently have HS4 SUs on my 1966 MGB and they perform flawlessly.

I don’t recall having any trouble with mine. Either the stock single or the mini pair. The biggest problem I had with the AA was the header always cracking at the 90° bend due to the longitudinal engine. I suppose solid engine mounts would have helped, but it was my first car. I wasn’t that sophisticated back then.
