What's the best way to learn about carburetors?

I'm 24 years old and recently ( 2 weeks ago) got a 1963 Ford Falcon Futura. I knew nothing about cars until I got it, I've learned the basics. Switched off the radiator pump, all the rust off the car, switched off the tires, put a new radiator, etc. But I can't figure out the damn carburetor, it's complicated from what I've seen and I was wondering if anyone has any suggestions as to how to figure it out. I learned everything as I went but I can't seem to find a new videos on youtube for my car ( only like 2 repair videos)

Youtube, bro…

Carbs are mostly all the same in the physical principles, but often very fussy about the details.

Find out what carb your car has. It might be the stock one, or might be something else. There are loads of books and probably some videos about that carb, regardless what it is.

I had a 1972 ricemobile with a Hitachi carb, needed to fix it, and found out that it was a copy, in reduced size, of a Chrysler carb from about 1959.

When you take the carb apart, be prepared for little ball-bearing check valves to spill out and get lost. Don't lose them!

I had to reassemble my Hitachi carb five times before I got it right. Your experience will be similar.

Carbs are not actually very complicated. You just need to think about what they do - from a standpoint of what they need to do. They need to mix fuel with air. However the demands of an automobile engine make it a bit more complex than if the engine ran at the same speed all the time. The engine sucks air into it and the carb's jets spray gas into the air column going into the intake manifold. When you step on the accelerator, the engine needs more gas so there's a part of the carb called the accelerator pump. It shoots in an extra amount of gas anytime the accelerator moved down. That's the basic operation. There are other parts and other things the carb does but once you get the basics down you can figure out the rest especially with all the information on the internet.

Although carburetors are essentially the same, some of the important differences are in the details. So, you're best to find out which carb is on your car and look for videos, books, or online articles about that particular model. In the old days, we would buy a "rebuild" kit that contained gaskets, springs, and other parts but I don't know if you would be able to find such a kit these days for a carb that old -- maybe on eBay?

Some sound advise so far, get the model # and series of your carb, a 63 Futura isn't going to have too exotic of one unless swapped. Look up how carbs work in a general way online, find a parts diagram of your carb and acquaint yourself with it. If you have a local U-Pull yard in your area now is the time to spend a few bucks and get something similar to your carb for year, engine size and general design, thinking the Ford even with a 260 V8 aren't running a 4 barrel. Use that carb to tear down and see how floats, bowls, and jets interact. And yes, you need a clean space and ability to keep track of pieces, not critical on a practice carb but still important. DO NOT pull your carb off yet unless you have a replacement ready to go in its place. And as others said, the physical process is just mixing air and fuel, but the ratios have to be right and under all conditions. There's often a vacuum line involved with the carb/manifold someplace too, sometimes to advance the timing and/or assist power brake units.
Practice with the junkyard carb a few times to see why sometimes floats need to be adjusted manually (per videos or rebuild manuals). Yes, you can get an old Ford shop manual too if needed. Biggest thing with carbs is that any adjustment in one input can change how others have to be adjusted so balancing one is tough. Yeah, LOTS of tiny parts too…

Find an old Motors manual at an antique swap or Ebay that covers your car, year. Fantastic info on air bleeds, etc.

If you can peee without wetting up your shoes, you can learn how to rebuild and adjust carburetors. Go to the public library and Get an OLD book titled "Fix Your Ford". You should be able to read and understand it since it also has lots of pictures. The engine has a water pump, not radiator pump. You need to stop where you are and take a basic auto mechanic course at a community college. The 63 Ford Falcon is one of the simplest cars built. If you ever put together a 50 piece jigsaw puzzle, you're smart enough to maintain a Ford Falcon.

Well a carbie is just a double tapered tube (venturi). Air drawn through the venturi by the movement of the pistons passes across the top of an open vertical tube (jet) whose other end is dipped in a fuel bowl containing gasoline. The fast moving air in the venturi has lower pressure than the stationary air in the jet (Bermoulli's Principal) . As a result gasoline is sucked up into the airstream from the float bowl and blasted into the engine. The bore size of the jet is carefully chosen so the correct amount of fuel is metered into the motor for the amount of air able to pass through the carbie throat. That's it in a nutshell. Naturally a jet can only deliver a prescribed range of fuel, and since engines don't run flat out all or nothing, and fuel coming out of a big tube into slower moving air is unable to vapourise correctly and forms big drops that are hard t burn cleanly, so there are another couple of other smaller jets that take care of part throttle fuelling but work in the same way. Depending on the throttle position, tall these jets are progressively uncovered/opened and covered/closed by the movement of a throttle valve in the carbie body. An additional feature there's usually a flap which partly blocks (chokes) the airflow to increase the fuel air ratio for cold starting.

Carburetors are actually fairly simple in operation. There are probably DOZENS of YouTube videos out there that explain the basic operating principles of a carburetor. If you want specifics to repair the carburetor that's on YOUR car, it might be easier to just replace it with a new or rebuilt one.

  • Should I learn to drive with a Ford Taurus or Honda Odyssey or it doesn't matter? I've asked this question before, but I made a mistake when it came to the cars. I took 4 hours of driving instruction driving a Ford Taurus, but I was just curious if I should buy more hours or just train with my dad with has a Honda Odyssey. I'm in my 30s, so I'm looking for mature answers. Would it be hard to learn on a larger sized vehicle? I drove it once, and it seemed all right. Any advice is appreciated. TIA
