Do You Still Drive a Car with Carbs or a Choke?

[Rockefella]

I voted for the last option

[Fleet 500]

Just curious, does anyone on the forum drive cars with a choke or carberetor frequently, maybe as a track car or even better, a daily driver?

I sorta do. My dad's Accord has carbs. I pine for the simpler era all the time.

I do like the sound carbs make at WOT (wide open throttle) on a big engine.

My cars have:

'66 Plymouth Fury VIP 383-cu-in... 4 bbl Carter AFB carb. Has coil-spring type choke.

'69 Cadillac Fleetwood Brougham 472-cu-in... 4 bbl Rochester Quadrajet. Has coil-spring type choke.

'76 Cadillac Fleetwood Seventy-Five Limousine 500-cu-in... 4 bbl Rochester Quadrajet. Has electronic choke.

'95 Lincoln Town Car 4.6 L (281-cu-in)... Sequential multi-port electronic fuel injection.

Do they have fuel injection to carburetor conversions? I mean, there's nothing more simple (relatively speaking) than a car with carbs. You really can work on them with a hammer.

Yes, but of limited use now.
Emissions on modern engines is a nightmare and carbs would struggle in many cases to get the mixture right across the operating range.
New 3rd party ECUs enable competition tuners to do it all in the ECU now as opposed to the early "add-on" ECU units.
ON the Escort Twin Cam with double 45s you could see the throttle pump spray HUMUNGOUS amounts of fuel at WOT Most of which ended up coming out the exhaust 7mpg in forest stages !!

Sadly when you eek out the maximum from an engine then a carb shows it's limitations and you find lumpy tickover, fueling on over-run and horrendous to balance and adjust jetting !!

j, on the Midget which "MGB carb" as they had SUs or Dell'Ortos dependant on age
And modded on's usually put on Webers We had notorious problems with the Ds on the MGB as setup was VERY tempreamental to the car being level and we never managed to track it down. Instead fitted a tapered gasket to get them off "level"

They are SU's. One of my dad's friends worked at SU way back and set them up for us, they run pretty well.

We have a car at work that runs two 40dcoe's on 850cc.

My first bike a Ducati 860 had two 40mm Dell'Orto pumpers, they were quite trouble-free.

Perched atop the P-76 V8 is the good old WW Stromberg, two barells of beauty and ubiquitous hereabouts.

I just put a Webber two stages carburetor on my 1984 Chevette. Wow what an improvement over the original!

Now if I could get rid of the rust, the car will be perfect again.

That's quite an imagination you have there.

Too true! I drive a Fiat Abarth and its running with weber 45s it literally pumps petrol into the head and you sometimes get a blowback effect where the fuel ignites and combusts in the opposite direction spitting flames through the trumpets. Its not a daily drive but something you have to experience, the sound the smell etc modern motoring just isnt the same

my RX-7 has the original Nikki Carb.. not exactly known for being a good carb, but not terrible either. it has a manual choke, and would start on the first time if my battery didnt suck (new one here shortly). my old truck has a carb, no idea anything about it, with an auto choke. with the choke going, i could ride it up to about 30 mph.

would they fit a mini..?

Very cool.

Wow, I'm not even sure how to set the choke. I'd like to try just for the experience of it all.

I was wondering when you'd chime in.

you pull a knob, and after about 3 minutes it turns itself off. usually i use that as my signal that the car has warmed up, which rotaries must do. so i start it, let the engine scream with the choke on, go putz around for a few minutes, and once it goes back to being quiet get in and drive away.

I have BMW 2002 from 73, there's a standard carb on it now but I have a pair of Dellorto sidedraught carbs that are going on. I'm looking forward to the sound

Welcome to UCP, we are looking forward to a sound bite (40ties or 45?)

I got a carb on my car. With an electric choke! I prefer a manual choke but the electric one seems to be getting the job done pretty well.
