CARB'S 32 to a 34 adf

[106usj]

 
Im running the 32adf which i know now from this site is not the correct carb for the 2.0 T.C.
 Will the 34 increase power by much compared to the 32 ?. and is it worth changing i assume it is as the 32 is too small ?
Its annoying me knowing its not running the right carb.But the 32 is running ok.
Am i better just changeing it out ??.
 I read on an other page that Miro may have a 34 adf reconditioned and rebuilt.Or buy one on OZ ebay?
Miro if you still have leave me a message please.
ill be off line tonite till tomorow but will reply.
Thanks 106

34 ADF is a brilliant carb and when running right is a good performer. It looks like you've got a 1600tc carb fitted.

A Sport needs a 34ADF if not running twin carbs. I've got a few of these spare, but it's a case of finding them.

I feel like putting the 34ADF back on my green Sport as the 45'S require rolling road set up and are doing my nut in at the moment. Seems to be running to rich and is fouling the plugs.

Check out the inlet manifold as well as although they all interfit I am sure from memory 34adf one had slightly bigger ports than the 32 carb manifold

I forgot about that 131 2.0 tc engine i bought as a spare.Hopefully that will have the weber 34 and correct manifold on it so i can do a straight swap after a carb rebuild that is.
Only problem it is in my mates lock up 300 odd miles away.
No rush as i have the start problem i had sorted i hope and the 32 weber is fine just now (Touch wood !!)
I hope to collect and take home the spare engine in Jan or Feb nxt year its low miles guy swore it only had done 69k when he took it out of the 131.But it was used in competition for its last 6 months before i got it, Still it will come in usefull for many parts.

Where is the best place to get a rebuild kit gaskets etc for the 34 carb (ebay ?)
Also will it increase power by much replacing the 32 for the 34 carb ?

[mirafioriman]

Rebuild kits come up on ebay or try Matt at Eurocarb they usually have them in stock.

How much of a difference you will notice by swapping the carbs I don't know, but it must be better to have the correct one

Ok cheers Dave.

The 32, 34 refers to the size of the throttle plate on the throttle shaft, what will have more impact on performance is the size of the main venturis, (the poms call them chokes). The 34 ADF/ADFA has 24/26 venturis from memory, where as the 34ADM has 27/29 venturis, same size throttle plates, big difference in performance.

With regards to Davids comment about the inlet manifold for the 34 having bigger ports.
Can any one identify the following part numbers on the bottom of my manifold as follows when all the festive drinking is over that is 

FIAT 132 DB
4407484 C 8
G- A 591

The 32 adf 4 250 weber i have is from a 1600 as stated by Sav and backed up by Haynes manual page 188 bottom left
When i get round to fitting the 34 adf from my spare engine if the above manifold i have is ok it will save me removing it.
Can any one shed any light on wheather the manifold is for the 2.0 or 1.6 going by the above codes or let me know where i might find out ie web address. Thanks ...

This is probably a silly question but are you sure you've got a 2000 engine and someone hasn't swapped it for a 1600?

[106usj]

Theo. 
I am sure it is the 2.0 tc as ive checked the numbers on the block first thing i did.Also checked all other numbers on the car.
For some reason the previous owner has fitted a 1600 cc carb setup on it.The inlet manifold im not sure about.
Also the distributor cap im not sure about but all else tallys up....
I will investigate into why it has the 1600 carb and find out and let you know.
Cheers..

Ok Theo.
I was half right about it being a 131 2.0 engine. When i went to look at the car i checked the chassis numbers and data plate to confirm it was a Sport 2.0 when i checked the engine number stamped onto the block i just looked for the 000s and all was fine.
As discussed the carb is the wrong type i know that now so i re checked engine number and by the sounds of things the engine has been changed at some point, when i dont know.
The codes on the clinder  block adjacent to the distributor are as follows.

Engine number (132  02  000)  Manifold number is in previous posts and distributor number too
                         (073  47  15.)
So it is a 2.0 but looks like its out of a 132 as the 131 Sport  engine number should be 131 B2 ooo

Here is one on ebay in scotland also

I thought 2 litre Lancias had a different carb to the 2 litre Fiats. I'll check my Trevi....

Not the best of pictures.
?50 i think i will wait till i get the 34 off my spare engine in jan or feb that one would prob need a strip down and clean and new gaskets although it does come with the manifold if its correct.
