Pretty cool and wholesome see-through carburetor video.

So your grandkids can understand how we used to mix lead with acid and burn stuff to make our cars go.

30 years ago, the Subaru Justy was the last carbureted car to be marketed in the USA.
This is according to Tom & Ray Magliozzi. Unimpeachable.

[Paul Pless]

nope

jeep grand wagoneer and crown vic police interceptor kept their carbs one year longer than the humble subie

[Keith Wilson]

Not all gone yet though; I rebuilt the carburetor on my snowblower last fall. Might be the last time I ever do that.

[ron ll]

So the days of holding the pedal to the floor to start a flooded car are gone?

I miss a lot of things from days past. Carburetors, not so much.

[Dan McCosh]

Just installed a new Zenith carburetor on the boat motor.

[Canoeyawl]

When they started putting electronic controls on carburetors things quickly went south

[skuthorp]

I remember twin SU's…………… not fondly………….

Last car I did most of the work on was a Volvo 122S. Those SU carbs were a new thing for me, and not fondly remembered.

[Figment]

I just stumbled onto my old uni-syn the other day. (in the bottom of my electrical-stuff bin?)

I'm a snail guy nowadays.

[Canoeyawl]

I really like SU's!

Dead simple carbs with a broad selection of needles, easy to tune they have good performance potential
Once they get past about 50 years of use they do need new throttle shafts and bushings. A slightly advanced procedure requiring a few tools. When that is done along with new float valves they are as good as new.

[Yeadon]

The jets on my 1982 Chevy S10 used to freeze up as I crossed Snoqualmie Pass each winter. The truck would power way down until it basically died. I’d sit roadside until the warmth from the engine would melt the ice in the jets. Then I could get going again. I don’t miss carburetors.

Carburettor icing does not ice up the jets, it actually blocks the choke, i.e. venturi, of the carburettor. It occurs because there is a temperature drop when the air goes through the venturi, so cool, moist air gets even cooler, drops below freezing, the moisture in the air condenses and freezes in the throat of the carb, blocking it.

My old Datsun 510s used to do it quite frequently, when I forgot to switch the valve from "summer" to "winter" on the heated air intake on the air filter housing.

[Canoeyawl]

Fuel injection unless directly injected into the combustion chamber can also have issues with induction icing, but under most conditions the nearby engine heat will prevent icing at the nozzles.
It's the law...

[robm]

I think the throttle plate can have the same effect on temperature as the venturi.

Many years ago, I calculated the theoretical airflow through a Holley 750 4 barrel carb, based on the pressure differential and venturi dimensions. I was astonished to find that maximum flow calculated was 748 CFM!

[Canoeyawl]

As a gas expands it cools, the mechanism is moot

Three Stromberg 97s.

Nice!
One of my "charges" is a '57 convertible with the factory 2-4bbl power-pak, and overdrive. Odd air cleaner and throttle linkage that one
Black w/black top and Salmon (or Coral?) interior!
What a beauty, I had to make up and install power steering using early Corvette components. Finding a replacement standard shift steering column/shaft to modify was the largest hurdle.
A California Car out of the box built in L.A. there is no rust anywhere

[Jimmy W]

My lawnmower that I bought last summer has a carb.

[Canoeyawl]

It would be fun and educational to add thermometers on either side of the venturi
