weber 34 ICT / ICH

[Jinx]

Hi,



Does anyone here have experience with a single 34 ICT / ICH on a 1.1/1.2 litre OHV engine? It's supposed to be a direct replacement.
I am most curious about possible performance gains and/or fuel consumption it provides.

(it will be used on a 1.2S or 1.1S kadett B engine)



Thanks!

A Weber has just about got to be better than a Solex - 'specially if new!

I got a pair of them to fit onto my 1.2 'SR' motor (1.1 bored out for bigger pistons) but have not got them on yet as their flanges have the bolts at a different angle to the Solei they are replacing and I had to get another manifold to modify (got the manifold - but job not done yet ... )

The only reservation that I has is that the Webers are a more modern carb that are probably jetted lean for emissions control on later motors.

PS: Don't mind Otto - he corrects us all!

Go for it - though well running 'old' single barrel Solei are no where near as problematical as the 2 barrel version used on the 1.9L motor (IMHO)

Solei - plural of Solex - love it!

I have used solii in the past - but the spellchecker insists upon solei

Latin tends to use the double ii for the plural - and solei may be something to do with the sun.

Maybe Otto can cast some light upon the matter?

Thats the thing. The PDSI's are known for their reliability here, so that would be no reason to spend money on an ICT (which doesn't even have a choke), based on reliability . So the only reason would be more performance or less fuel consumption.
Either way i'd swing towards a progressive carb for economics and oomph
(like the 28/36 DCD, for which special manifolds were made back in those days by a dutch company. impossible to find though)

Either way i'm quite reluctant to get the ICT. From what i can find, possible gains are marginal on a stock engine and on a modified engine i'd go for a bigger carb (like DCD or equivalent with a custom/reproduction manifold).

The reason for a downdraft is Belgian Technical check i have to pass each year, a DCOE is a dead give-away that i played with the engine (which isn't allowed), while a downdraft looks more stock and requires an expert eye to see.

The ICT/ICH is pretty hot in the VW scene but even there, nobody seems to have put tested them on a dyno so there's no information about performance gains (that i could find). There's much debate about dual solex vs dual ICT, so no obvious winner.

I guess i'll leave it for what it is, and keep the 100-150 euro i would spend on that carb to restore my car. Then i'll evaluate the finances to see what kind of engine mods i can afford

in any case, thanks for the advice, guys

the 34 ICH usually has slotted holes on the base, so it will fit a number of applications. Weber has felt that sometimes this carburetor will replace a 2 barrel stock carb. I would say the reason to replace with the weber one barrel is for parts availability more than anything. We sell these mostly for old Land Rovers, and they work fine.

You will be able to tune for economy as well, as the jets are the same as the DGV series.
