I've always avoided carbed cars because I don't understand how they work. But this is silly, I have access to the internet plus a $150,000 piece of paper called a mechanical engineering degree, anyone got any good links?

Half the fun will be identifying it! (I think it's like a Weber?)

once you realize all a carb is is a controlled fuel leak, it gets simpler. Lots of variations on a simple theme. I cut my teeth rebuilding Bing carbs on mopeds 20 some odd years ago.
Start there and learn from that

If it's a Lucas carb then he's really screwed.

Weber's are fine. Just those cheapy "hot rod" carbs people put on stuff are usually crap.

It is just a venturi. Due to the constricted flow, pressure is reduced and pulls gasoline from the bowl into the air stream where it is hopefully atomized and mixed with the air. There are a few more things going on, like the float and needle valve that keep the bowl full of gas (basically an on/off valve for the incoming gas). There's the idle mixture screw which controls how much gas gets sucked in at idle. There's the "jet" which is just an orifice which controls how much gas can get sucked in at WOT. There's an accelerator pump which gives it a little extra squirt of gas when you push the pedal to get things sped up and the venturi sucking harder. There's the butterfly plate which is connected to the throttle which controls how much air is going through. Then there's the choke which is a temp controlled control for the air because for some reason I don't fully understand a cold engine needs a richer fuel/air mix.

It's a toilet with different ways to regulate flow to the bowl/engine.

I got my friend into bikes a few years ago, and he has started working on/tuning his own so he asked me to share these sorts of articles with him. He is a Civ Eng, and I'm working on my second degree (Mech Eng) but it really doesn't matter, anyone can learn this stuff. I will have to do some digging, as I had a few really nice ones that I shared with him, but the most recent was this one: http://www.roadandtrack.com/boot/taming-th…
As has been mentioned here already, they are quite simple in principle. That article is a good basic starting point to understand how they work. I had some better ones for basic tuning. I got really quick at tearing down and tuning carbs when I was working on my old R6, with four nice little carbs all in a row. Dirtbikes and others, with easily accessible and relatively simple carbs, are a great place to start!

The tuning on a Solex is really basic. It's the rest of it that's batshit.

And now, a joke.
How do you know someone is an engineer? Don't worry, they'll tell you...

Start rebuilding simple carburetors and it will be easy to learn in no time
