Reduction of CO emissions during warm-up for carbureted engines.



mum mum vador, knock it off. for all practical purposes there are no carbueted
auto engines on the road for a very long time. I believe that last such sold
as new was the miserable CVCC engine, and that was well more than 25 years ago.

You really should stick with what you don't know.
I happen to have - in my driveway - a 1987 Caravan - that is not only
OE with a carburetor, but open loop (no fuel control computer and
exhaust gas oxygen sensor) to boot. It has a manual transmission, too.
(and something close to 180K)

That puts you wrong by about a decade.
