The SU was a very clever and efficient design but there was a lot that
could go wrong with them. The Stombergs were bad news with their
rubber diaphrams and such. Most US mechanics screwed all of them up
when they first got their hands on them, and of course being
manufactured in Britain they wore out prematurely. I never learned
anything about a solex carburetor, even out of all the bugs and buses
I had, because nothing ever went wrong with them and I never took one
apart that I can recall. But when it did, you could grab another one
and tune by ear and go.

I was called on to balance multiple solexes on friends' Squareback and
Notchback VWs, but being out of balance was hardly ever the problem.
It is for one of these that I'm hanging on to my Unisyn : )
