If your stock carbies are working, then I would leave them on. They are set up well for the stock motor.

hey pete, yeah well therev been tuned proffesionally etc, but they seem to eat the fuel a bit, just thought it might be easier and cheaper to run a
single, but i was reading the single carby manifolds tend to ice up in cold conditions, so i dont know if i should go this options, what do you
think?

A single weber will eat more fuel, the stock carbies are actually not that big. The other option would be twin Kadrons, Stan Pobjoy does a conversion
kit for the Kombi motor. All the 2lt motors he is doing with them are getting 28mpg.

You have to compare what "eating the fuel" is?
Our 1600 Beetle is using as much fuel around town as the Bus. I would say it is using more than it should, and the bus is being very respectable. All
comparative really.
You have your original twin carbs on now, not costing you anything. Any other carby setup is going to cost money to buy, put on and tune.

More efficient - drive it less, and when you do, drive easy on the accellerator pedal.
More power - equals more petrol.

What are you going to pay for the prog??
There is a set of 44's for sale at the moment for $650
How much more is that than the progressive
Progressives like heat - and the Type 4 motor cant be tapped for heat like a type 1 motor can.
Add to that the extra width of a type 4 motor and the fact you live in Melb and your fule will be falling out of suspension b4 it gets to the
clyinders.

I've heard the TIV gets pretty torquey with a single carb. But it won't do well in cold weather... As has been mentioned.
I get around 11litres per hundred km in my twin carby 1800. That's completely stock. 28mpg is like 8.4litres per hundred, that sounds like a bit of
a stretch to me... Great if true though!
Single carby'd have to be a crapload easier to tune than any twin setup though... If you're into doing that sort of thing yourself. They don't
need it that often do they? And in terms of reliability, I also had a stuck needle valve with fuel dribbling everywhere once. And it used to also
stick shut, meaning two cylinders would stop working. Reliability _might_ be better with a single..?
Anyone have experience with a single carby TIV?
EDIT: here are some people saying that stock twins are better than a weber progressive:

I have one on mine. The originals wore out and I got sick of having to tune them all the time. There is a slight flat spot on take off and it seems to
lag a bit, then when the secondary kicks in it takes off, sort of like turbo lag or two stroke powerband effect, you just have to adapt your driving
to suit. When you are going up hills if you can keep the revs in the peak torque range she really pulls hard, and holds the revs longer and better
than with the stock twins. I live on the NSW QLD border, so its realitively warm all year round. If I lived in a colder climate I think you would have
problems with this set up that would make it not worthwhile, but then again I see that they sell this set up in the UK so I beg to wonder? If I had
the money I would definately go for a set of 40 or 44 twin Dellorto's on a stock 2ltr. I got the progressive for $80 and put a kit in it, so it was
cheap as. This will have to do until I get the motor rebuilt and can afford the Dell's.

28.3 mpg is 10km/L or 10L/100km

Oh really, I was lazy and just used Google (its unit conversion facility). Perhaps it's a US/Imperial thing. Stupid nonsense units, grumble
grumble, dumb system... Grrr. :P

I used to have one of these on my 2L kombi. Horrible flat spot in the middle, not great power, terrible icing in winter (which you WILL suffer from
in Melbourne), difficult to start when cold.
I took it off and put stock dual solexs on. No flat spots, BETTER overall power, no icing whatsoever, great for cold starts.
The answer is simple. Go with stock dual solexs for a stock 2L.
