It's great to hear that the Green 2.2 didn't go to waste for nothing 

Great looking job by the way Anders...

Problem is indeed solved, and never has the configuration run this well. Hot, cold - it just pulls nicely from 2000 rpm and up and fires up easily. I have a flat spot around 1500 rpm, but nothing bad, so this might be the right time to go on the rolling road. Still, I have to gain some confidence in the setup, but the running problems are history now! and I'm very happy

Oh yes, that would have been a pity if it did. I'm using it's engine loom to make a new one, the thermostat housing is the one I have running now, the distributor has been restored and will go on my car eventually, and the spring cups I have on my rear end comes from that (as you know, Valdemar!)

Great looking job by the way Anders...

Thanks. I too am quite satisfied with the look, and it performs quite well too: I took it out for a spin this morning (to work), and boy what an acceleration and SOUND in 3rd from 2500 to 5500 or so...

Second stage progression isn't good though, but the new ignition coil does wonders to overcome it. The cure could be to go down to 34 mm venturis, but they aren't cheap so I have to try a few other things first. Also, it's loosing fuel in the float chambers over time - the level drops some 5 mm when the car is standing. I think the fuel seeps out of the acceleration pump jet? This is probably due to the 15 degree inclination of the carbs, which is 10 more than Weber recommends, and with the way the starting system and accel pump is made on these carbs, it can cause problems. In hindsight, I think Dellortos could have been better in this respect?

I'm not optimistic about the project though - the Espace has hit us hard with the timing belt change, which due to ridiculous prices on spare parts and a lot of faults discovered in the process will cost us a fortune, so I will probably have a difficult time negotiating funds with my wife... Shelving the DCOE's and converting back could be a possibility, at least for a period...

I have a pair of 40mm's I'm not using, if you want to experiment

THANKS, I really appreciate that

I'll keep it in mind. But I'll look more carefully into the problem and discuss it with knowing people before I do anything. And it has worked for others... (thinking...)

Just tried a new idle jet - and result is very good. Blog is updated:

I've written two entries since last pointer here:

Sounds like I should get myself a set of DCOEs and ship them to Dk for some love, care and adjustment...  hehe

[Anders Dinsen]

Gentlemen, there's a new post on my Weber blog, if you're interested.

How much did you have to pay for the Webers? I come across some(new perhaps since it was a tuning companys ad) in a norwegian car magazine, at the price of 3100,- NOK(387euros) for each. Will try to find them again, and see what more I can dig up on them.

I have diagnosed the "carburettor ice" problem - it was not ice at all, but a failing component. Krede in particular will enjoy reading this latest blog entry:

That sounds okay for a new carburettor. I buy parts from this company: http://www.fastroadcars.co.uk and he sells a new 40DCOE carb for 257 GBP (2625 NOK). Mine are old, though, probably even older than my car, so I got them considerably cheaper than that (and in fact didn't "pay" them with real money - I swapped them with Hans for a good cylinder head). I've had to spend a fair amount on parts, so in the end it may turn out to be not much cheaper than a set of new carbs.

Webers are generally expensive, and not better than Dellortos, so I actually suggest you go for a set of those instead. They can be found rather cheap on eBay, and don't worry about buying a used set because they are usually easy to clean and get back in shape. Parts for Dellortos are available from http://www.dellorto.co.uk/

But don't forget that you need a good manifold. A manifold is a very critical component! Simon lists a reproduction Murena S-manifold in his catalogue, but you should check with him if he has them in stock or not. Also, I don't feel that my (reproduced) manifold is quite up to standard, so you might want to check the work before you start your project. For example, the fixing studs for the carburettors were not perfectly in line, as they need to be to achieve good syncronisation between the carbs.

And the absolutly first thing you would want to do is buy some of the books I mention here:

You can get a set of used ones for much less than that on ebay.

I think they usually turn out too expensive in the end of the auction, though the 40's are usually considerably cheaper than the 45's. You'll get more value for your money with Dellorto's on eBay.
