My engine can run but I think it would be better to overhaul the carburettor. I have Solex but it is not easy to find a repair kit for it that is why I am looking for more infos about Weber carburettors.
First, you can get the Solex 34CICF service kit easily from a company called B2H (at least, the last time I had no problem) and this comes with most of the gaskets, seals and a needle valve, if I remember correctly. http://www.b2h.fr/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=34&category_id=14&option=com_virtuemart&Itemid=2However, the tiny 'O' ring for the pump jet feed was usually too big, so you may need to get that elsewhere. (in the latest photo of the kit it looks about right now - maybe they've corrected it?) Weber do a seal of the right size I think. Also be careful when replacing needle valves. I remember someone once replaced one only to find the car didn't run properly afterwards. The new valve was leaving too little fuel in the float bowl. Second, since there never was a Weber fitted or specified for the Murena you cannot simply replace the Solex with a Weber. Yes some Weber 34DMTR will fit physically, but there are many different types of 34DMTR and whilst some can be altered to suit the engine, others are really not suitable. The Venturis are cast in and cannot be changed as this is a 'cheap' Weber specifically made for a manufacturer for a specific car/engine. As an example one version has a connection to the distributor diaphragm that is totally wrong. The carburettor take off point should have no vacuum at idle and then increase progressively as the throttle is opened up to about 2500 rpm when it stops increasing. (there is a vacuum advance curve in the workshop manual) At least one version of the Weber 34DMTR has full vacuum at idle, then dropping as the throttle is opened, which is the opposite to correct and is totally wrong. So far the most ideal 34DMTR I have found from the ones I have seen is not quite right and needs some changes but can work. However, if the Solex 34CICF is still good but just needs to be cleaned and serviced this is often better as you know they work correctly with this engine. Regarding fuel levels in the float bowl, the latest fuels, particularly where they contain ethanol have a different specific gravity which will affect the height the float will ride at, and consequently alter the fuel level. You may need to adjust this to get back to the original level. Roy

I was going to throw out my old steering wheel as some of the rubber has come off the back, and the gear lever has gone rubbery and soft. But may be I will do what you have done and simply get them recovered. They look great, as does the whole interior.
Yes the old original steering wheel feels a bit like SM stuff. Touching it gave me the chills. I replaced it for solid wood. Feels a bit like my old MG in the 70s. First it looked like this but with a Alfa center. Was a bit to 70s so I chanched it to this. Not everybody's choiche I think but I like it. The car has a brown leather interior so mounting a black one is not done and brown is hard to find. by the way, your interior looks very need, but if I change it the buttons will go. Herman

1m83 = 6 foot do fine. Much more will have a problem. Most of the people that converted to leather complain seats were much higher but that's normal I think. My 1.6 has the old type leather from Car-joy and after some years it got settled. It is quiet old now and needs filling but sitting is OK. The seats can't get much lower because of the construction. I saw no opportunities to do so. Herman
