As a question that me and a mate had a funny argument over some beers....we came to the question of which fuel/air system is better. Naturally, I went for a carburetor. Now I pass the question to you guys.

I like the way that something well set-up with carbs and a dizzy will start instantly - now of this two-full-turns of the crank so the ECU can work out what's going on.
OTOH, for a tuned engine carbs and dizzy are a lot of work to get right - loads of jet (or needle) swapping - while EFI's just a case of adjusting some numbers on a computer.
Horses for courses - I like both. Thankfully, I can choose different fuelling systems for different cars. However, if I were forced to chose one though, it'd have to be carbs: more repairable, and more fun.

I don't think you can beat carbs for simplicity, induction noise and throttle response, let the engine take what it wants!
They can be easily set up roughly by feel, unlocking aftermarket injection which needs a lot of dyno time to set up.
Replacing stock injection with carbs normally releases a fair few horses too!

I think the American market is close minded of carburetors (except the muscle car enthusiasts). Coilpacks, computers and electronics just aren't worth the money and time to install.
My overall point is to say if it came out of a factory a certain way, keep it such

never got on with carbs at all, but that i blame on only owning vws with worn out pooburg carbs fitted to them. 1990s fuel injection for me all day long! still pretty simple, easy to tune but none of that fancy stuff you find on modern fuel injection systems.

Early 90's fuel injection. Crank sensor, etc is a lot of trouble when it breaks, but hate carbs.

bit of both really, Love fiddling with carbs, getting the best out of them turning the dizzy to get the best bite of idling and kick up, but for just getting to work n back and mundane stuff injected just turn and go
So weekdays injected, weekends Carbs!! Man has to potter

I think the carb set up is a grey beard thing, over 40 + years of age, You always had carbs n chokes when you passed the test 30 somethings came into the motoring world with injections

Carbs for fun cars and Injection for sensible cars.

i love carbs but for power its got to be injection/throttle bodies a set of twin 40s sound nice but unless you keep on top of them they go out of tune and use more fuel and in the winter...... injection you plug the laptop in you can see what needs doing you do it and it stays fixed.

My Golfs' Carb is the first car I've had with such, enjoy it for it's old school attitude of throwing air and petrol at the engine to make bang bang!, but I also F ing hate it because it's never quite right....chuggy in the cold, over rev's in the warm. Pooburg for the bin - GTI next.

Fuel injection is obviously better. But it uses magic involving 1s and 0s. So, ....those will do nicely ta.

OMG - please tell me you bought these and I can now buy them from you I've been after a set of those DU6s for - very long. Must be a decade allready... ;D And btw: a aftermarket EFI does not neccesarily need a dyno to set it up. It's witchcraft after all (self learning via target lambda ) Generally I think a EFI is much easyer and friendlier to engine modifications, as it can adapt (albeit not unlimited) to an altered environment (like a different air filter, exhaust manifold). A carb has to be tuned manually every single time. Of course there's the added simplicity of a carb - but it has it's price I do love carburettors for they'r simplicity and I sparked a hugeargument when I recommended the Mini folks (you can guess where) to use SU HS carbs over HIF carbs - as they'r much easyer to maintain, repair and have way less stuff to them that can go wrong. But my most favourite carburettor is this one:

OMG - please tell me you bought these.... I wish! My pockets are not deep enough/bottomless. Those are the only ones I've ever seen. If I had bought them I'd never sell Tempted to try and make my own twin choke SU at some point. Agree. Just having the float chamber separate makes it so much easier to fiddle with.

I have twin weber 40s on my 1.4k series, the induction noise is brilliant and I love the way it spits and barks on the overrun. But it's a devil to start in the cold, uses too much fuel and didn't make as much power on the dyno as cars running standard injection.... so they're going and I plan to switch back to injection. Carbs on a classic, injection on modern engines. I wouldn't advocate going to carbs from injection, run TBs & injection instead

^ what he said.
For an every day car, injection all the way.

I'm a fan of both. However, each has their place. Carbs do have a charm about them and have been the backbone of many a tinkerer over the years in addition to being seemingly unstoppable (I.E fixing them at the side of the road etc). But the fact that EFI can get it right first time? Tempting? Do either belong to their representative cars (I.e Injection for new stuff and carbs for old?) No . As for those saying nothing sounds like carbs, I shall say two words in response. Throttle bodies . Anyway, time for pics:
