What's wrong with SUs or Solexes?????? Are they so bad? One of the reasons I
like my Roadster is because it's simple without all the damn wiring and
vacuum hoses running around the engine compartment screwing up the look.
When I open the hood I appreciate the simplicity and the fact you can
actually see an engine in there.
If I want to see fuel injection lines and vacuum hoses I can always look at
my Integra or Miata.
I never had a problem with SUs and that's probably with a running time of
30+ years between my Roadsters and my Zs. That's a lot more than I can say
about FI.
