Not everyone is a mechanical genius.

I found it vey interesting.

Needs a follow up on carb balancing, tappet adjustment, points and plug, cleaning and gapping. Head off decoke optional.

I remember that stuff, give me ecus and injection any day. We all bemoan cars becoming appliances, but there are some definite upsides to not having to spend half an hour fettling a car at the weekend so it will start in winter.
Tappet adjustments are still needed on some cars and plugs still have to be replaced. Carb balancing shouldn't need to be done regularly unless all the linkages are worn out.

Next week on PH. "What is a spark plug and what does it do ?"

JHTFC.
An article on how indicators and mirrors work, and when to use them might me more useful.
Not for the average Audi driver surely......biggrin

Not bad for a simple article, just covering the basics. Ready for lesson two - how to set the thing up!

Like it or not, many people on here will never have driven a car with a carburettor. I’m 34 and I haven’t..

Anyone know what the newest car is that was fitted with one? For arguments sake let’s just restrict this to the U.K. market, not some Eastern European continuation that’s still getting stamped out...
I'd be interested to know them last car sold with carbs.
My money's on something Rover ish..
Most of them died out around 1992 when the cat requirement came in. Some Rover products did run carbs with a cat, the Mini, Metro and I think 214S. They were all gone though by 1993/1994.

I think the last ones were the Ladas, which left the UK market in 1997, but still had carb engines, with cats.

Odd article. Perhaps one on what the battery does as well please?

No mention of the tried and tested technique of unclogging a carb... ie take the air filter off, rev the knackers off it and shove your hand onto the top of the carb until it floods and stalls smile

fk me backwards, the PH Miserable bd squad has got stuck in to this quickly, haven't they?

It's not a bad article as a brief overview of what a carburettor is and as a broad description of its function.

Like it or not there's loads of drivers around now who have never driven, owned or even been in a carburetted car. They were being superseded by fuel injection when I was growing up; in the late 80s a lot of ordinary family cars still used a carb, ten years later none of them did.

As an example: My first car was a 1991 Fiat Uno, a bottom of the range model which had a carb and a manual choke. The better models were using injection by that point, and this was a cheap Italian shopping hatchback - the point being that it's well over 25 years since carbs were mainstream!

If you can find an old book called the AA Book of the Car (usually a few copies on eBay), that had some excellent descriptions and diagrams explaining how carbs worked. It was published in the 70s but most of the basics still apply to the mechanical aspects of modern cars.

We've got a whole generation of people brought up on fuel injected cars. IIRC there hasn't been a carburettor fed engine on sale in the UK since 1993 when the catalytic converter became compulsory. Fuel injection was required to prevent any unburnt fuel from fouling the cat.
Therefore there will be plenty of people who have never driven a car with a carburettor and manual choke, who may well be interested (or not) in how it functions.
I'm wondering if the fear of rear wheel drive started with that same generation? I was watching a film on the YouTube the other day, where this young lad was talking about replacing a 4WD Audi with a RWD BMW and his biggest fear was having to drive it in the rain because of how dangerous RWD is.

Good god. I drove my BMW to work in the wet today and don't recall dying once!

Also, to add balance, I'm 26, my first car had twin Stromberg carbs, with a manual choke.

Some of the people on here are ridiculous.

Just because i am a car enthusiast doesn't mean that i know the inner workings of how everything works. rolleyes

Especially for something like a carb, which is a rare right these day.

Look forward to reading some more articles like this.

BTW, 37 Here and never driven a car with carbs.

It does seem that there are many more that feel they 'need' AWD to be safe. Nowt wrong with RWD in the UK. Copes fine with snow and ice if you can drive accordingly.

As for the article, I don't get the elitist criticism of it. It's a basic layout of a redundant (in cars at least) tech. I'm interested and only semi knowledgeable about. Why the anger?

I'm 30 and I never have driven a carburettor equipped car either. AFAIK the last UK market car was the Lada

Accelerator pump for smooth running? Really? It is to enrichen the mixture under rapid opening of the butterfly, otherwise the mixture would be very weak.
Yes, so for smooth running. rolleyes
