I'd like to put a new Weber carb on my 95 and I'm wondering what the most sensible way to achieve it is.

I've done the job to VWs in the past using an off the shelf conversion kit - this route is appealing if possible, and I've noticed Ashcraft do a kit, but no idea of cost or quality. Any other options to this approach?

If I were to go DIY how much fiddling is involved in terms of linkage and air filter mounting, and what do I need in terms of an adapter plate or manifold?

Thanks!

I've been following this thread for a while...
... and today Parcelforce dropped of a nice new shiny 34ICH from Fast Road Cars. This is destined to go on my 95.
I'll let you know how we get on... just don't hold your breath

Thanks the comment Melle here and in the other place. The engine now runs and we beginning to go through the things that will hopefully get it running smoothly. May take a while but as you say we are learning as we go.

I know nothing about ICHs, but please do not try to clean jets with a piece of wire or a needle or you'll ruin the bore; only use compressed air/ carb cleaner/ ultrasonic bath.

Hi folks having read this thread with interest I hope someone might know the answer to our issues. On the yellow 95 project (sorry no photos still!) we have a Weber 34ich. It has a 27 stamped on the body which I presume is the right one.Having fitted a kit the accelerator pump still doesnt work manually or on the car. Float chamber seems to fill properly, the suspects are the small jet at the bottom of the float chamber and the pipe in the casting to the pump. Can they be cleared with air or manually? Is the brass plug the one referred to in a previous post on this pipe?

Cheers Dave

Really hard to start. Then it'd only idle with choke out. Obviously wasn't getting any fuel through the idle circuit so I removed the idle jet and the mixture screw and blew it out using a tyre pump. Put it back together and no change. Removed the idle jet, pumped more air through it and noticed some air/fuel coming out of a hole just above the idle jet. On the inlet manifold I found a little brass plug that fitted the hole. For some reason the Weber 34 ICH has a hole just above the mixture screw with a brass plug in it. I was lucky it only blew (or fell) as far as the manifold. I'd imagine an air line could blow it far far away, so I'd suggest putting some tape over it before blowing through to clear blockages. I still don't know whether it fell out and that was the original problem or whether I blew it out but either way, when I put the brass plug back in the hole it all works fine.

Man, it's been a while.
I got the 34 ICH mounted, but I've now been confronted with another dilemma.

The old exhaust pipe for the car was mostly rusted out, and I'd like to replace it with some new stuff. The problem is, I don't know whether to upgrade it to 2 inch, like I've seen a couple guys do, or simply replace it with 1 inch?

The 34ICH uses an alloy adaptor ring on the top and this usually, I think, comes with the kits. If you use that, the standard late filter housing fits perfectly. The same ring fits all of the ICH sizes, 25-27-29. FastRoad etc should have them if you don't have.

The early metal air filter can be adapted and looks a lot better than the plastic housing. You will need to alter the brackets (that attach to the rocker covers) and trim the lower edge as it sits a bit higher on the Weber (it touches the bonnets "hinge beam")

'73 96 (Vernon),'74 95 (Veronica)plus 4 other 95's and 2 96's

I put a Webber on my last 96 but have forgotten what I did for a later model retaining the plastic air filter.

I had to get different rocker covers off an older model, I think as they had different fixing points for the air filter.

I needed a reducing kind of foam gasket for it to fit the top of the Webber I think!

I think I needed a "manifold" or something for it to fit the top of the engine which were hard to come by.

Does this sound right, any idea re supply of possible said parts and where do I get the Webber from, a guy in Wales sells the genuine ones I think I read! Thanks

All the details in my post are illustrations drawn from other sources and my own experiences, so don't break yourself trying to get the exact match - each carb and engine will differ anyway.

Plus, you will be able to change the various jets with the carb in place, so go ahead and fit what you have, then enjoy the process of tweaking!

In any case, the pump jet controls the "squirt" of additional fuel used on initial acceleration to keep the mixture rich enough to cope with the first seconds of demand. Your 50 jet is fine as a starter, though you might find the engine stumbles slightly if you open the throttle suddenly. Chances are that you will only notice this when standing over the engine and operating the throttle by hand as the foot is rarely as fast as the hand. (or is that just in karate films?)

Best source of weber parts is Fast Road Cars - very helpful, and they are pretty cheap items, so if you are placing an order anyway, I suggest you buy a range of main jet sizes so you can experiment.

Regarding the choke question, a little confusing - do you mean that there is no obvious connections to the choke "flap" at the top of the carb...or are you saying there is no flap at all?

If so then I am afraid you probably have a Weber 34 ICT not ICH.

Thanks for the help Andy.

Yeah, I worded that choke question badly.
It has the whole choke linkage assembly on the carburetor itself, but it does not include a choke cable. This is why I was wondering if I should purchase one.

Here's a link to the listing on Webcon that I got the carb from:
http://www.webcon.co.uk/shopexd.asp?id=738

I realize that it says this model is for a 1.6L engine, but after looking over the internals of it, I really don't think that matters.

Additionally, here are a couple of pictures of the carburetor I received: http://imgur.com/a/w7egK

Hello again everyone,

Well, I finally got the 34 ICH, and here are the stock statistics:

Main Jet: 150 (155 included)
Air Corrector: 175
Emulsion Tube: F6
Idle Jet: 50
Pump Jet: 50
Venturi: 27

Now, going by Andy's instructions back on page 2, I will be needing a size 55-size Idle jet, along with a 40-size Pump jet.
But so far, I haven't been able to find a size-40 Pump jet anywhere, so would a stock 50 work for now?

Additionally, my carb didn't come with a manual or auto choke. Will I need to purchase one of those?

Nothing wrong with Eurocarb. However, I prefer to buy from Fast Road Cars in Wales, knowledgeable chap and top notch service.

Sorry, no knowledge of Eurocarb, but have dealt with Fast Road Cars in the UK http://www.fastroadcars.co.uk/shop/index.php?act=viewDoc&docId=2.
You could try Jack Ashcraft http://www.subrew.com/jackashcraft/ at least he's on your side of the pond!
All the best.

Hello everyone,
I've been looking around online for the correct 34 ICH carb for my 1969 96, and the only mostly-accurate listing I've found is from Eurocarb.com.
Currently, I am living on the West US coast, so I don't know much about the legitimacy or reliability of these European sites.

If someone could tell me if this site is indeed reliable, and if the listing is good, I would truly appreciate it.

Here is their listing for the carb:
