carbs for me, just for the lack of extra fuel pipes, sensors, wiring etc to go wrong.

with injection there's so many things that can be at fault if you get a problem, carbs are a lot easier to fix at the road side i think

Injection every time, far easier to get the correct mixture without faffing about with dozens of jets, and you can adjust all across the rev range. IMHO Ray

old school nearly always get you home depend on a pump, a spark and juice and no electrickery to make em go wrong, agreed that once injection is set up then its set for good.

Oh and there is that nice burble as you back off because ya knows shes overfuelled

Injection!!!!!!!!!!!

Best thing to spend your money on, parked my car up 6 months ago and then 6 months later i go out to it and turn the key and away i go, no p1ssing about with choke and keeping everything in balance.

Ive had carbs and never agen, plus much better mpg and the correct fueling across the entire rev/load range on the engine.

Move with the times

I've gone from carbs to injection. better power to fuel ratio. if you want a burble (off throttle) for unburned fuel its easy todo

Had injection fitted from start, 8 years now. Never gone wrong and I used s/h pump and injectors. Easy diags using a lap top to check sensors. If throttle position sensor, coolant sensor, air temp sensor or crank sensor stop working then you wont get a reading. To check the pump just listen, if it not running it's not working. The chances of all the injectors stopping is very slim, and they are easily tested or replaced if they do go faulty. Make a decent job of the wiring and fit a decent fuel filter and injection should be very reliable.

Injection is a quantum leap over carbs.

In theory efi, but! On a standard motor I think carbs are much easier and much cheaper. My bike carb set up seems to work just as well as TB setups I've seen with similar or better MPG and similar performance.

Bike carb set up is very easy to do - probably easier than efi. Mine have been on for a couple of years with no attention - the car starts very easily after standing for months.

I remember carbs! My grandad used to tell me about the one he had on his autocycle when he was a lad.

I thought carbs would be an arse to get emmisions through IvA. Not a bit, easy.
Both idle and 2500 revs is on idle jets. So just screwed in or out to get mixture correct. Did the at the test station.

I think injection however wuold be easier to set up overall. Every time I had to change the jets, all the carbs had to come off. 25 mins best time for carbs off, floats chambers off, change jets, float chambers back on, carbs back on.

EFi every time. More flexible, more efficient, more power. On the other hand more complicated Perhaps in the days of early EFi, carbs had the edge on "more reliable" but not any more. My old tintop is 14 years old and it's not been adjusted once, can't imagine the same could be true of carbs!

Bike caarbs for me, I reckon my venture into EFI has been a complete waste with no gain, and substantiatiol economy and money losses...

Hindsight is a wonderful thing, if only I could see it coming...

the question is name a mass production car in the last 20 years that has rolled out of a factory with carbs. I don't think you would need more than one hand. i had bike carbs on my pinto purely because the efi inlet manifold wouldn't fit and bike carbs were cheaper than tb's and a custom ecu. last year i drove the thing down to exeter and averaged 25mpg from a 1600. have just finished fitting a 2.0 saab turbo engine with ms3 efi and expect at least 30mpg for over 150% power increase.

why bother with carbs when with fuel injection you can have economy and power along with the ease of on the spot no tools required tuning.

I was running standard vauxhall injection but have now fitted r1 carbs they have got to be better than standard vauxhall stuff.
