which does not apply to the discussion at hand..
non-smog aftermarket dual carbs on a vanagon.

most likely it is a bare-bones installation with no smog complication at
all.

and yes....the very end of carbs ....they were quite badand complex.
See Honda too.  They work well though.
Notoriously ...the 'electronic feedback' carb was the last step ..a
missetp even ...
in going from carb to EFI.

if it was Friday I'd ask what SU ( the carb brand) stands for, but  it's
not fridae, and that's an old trivia question anyway.

carb-smarb. sometimes...user. Mostly .........no.

and if I had the time to mess around..I am quite sure I could retro-fit
subaru sequential, distributorless, knock sensor EFI and igntion to a
waterboxer engine.

it's all fun,
S.
