Hey all!

I am having a lot of trouble sourcing the Solex 4A1 to Weber 38DGES conversion kit for my 1973 280 sedan (W114). I want the reliability of the Weber and I am tired of stalling every few weeks with the Solex.

I have tried Red Line Weber and they no longer carry the carbs. Is there anothr good source for these kits??? Any assistance would be great!

Thanks,
Brian

thanks. i'll give it a shot. the question is, does he sell the carburetors? i can get the kits from Red Line, but they don't carry the carbs any more.

I'll answer both the above,the carbs and kits were supplied together.In the US there must be holley dealers everywhere?.
The four barrell solex was recognised from the very beginnig to be a lemon,I have one on my 280 also ,which runs good,But my car has only 75,000 miles on it.from 1974!.

mine is only 88k miles.

the problem with the carb has been posted here before.

the problem is with the brass float needle guide/sleeve that keeps the float needle in line with the fuel entry point. the guide is pressure fit and not mechanically attached to the carb housing. after a few heat/cool cycles, the guide moves up and out of place, keeping the float needle from allowing fuel into the float chamber.

i've taken the sucker apart about a dozen times in the last year, and i have come to this diagnosis. i push the guide back into the right spot, reassemble the carb and i'm off and running.

does anyone know of a mechanical fix for this problem? and is there a link for a Holley carb kit? i was only aware of the Weber.

I was reading on another forum you can just grind the plenium flat and mount on something like an Edelbrock 4BBl (the better carb IMO), or a Holley right on there.
ie. any suitably equipped machining shop should be able to modify your existing manifold to take the Holley (Edelbrocks have the same stud pattern AFAIK).
Just rip it off the car, hand it to 'em with the new carb and say something like, "I want this, put on there."

So it's just a matter of setting up some linkages. Easy, I go cable every time myself. I don't much like your chances finding an adapter plate between solex-holley. And I wouldn't even bother.

Besides, if you're going to go to that much trouble, why not think about setting up an aftermarket throttlebody injection setup instead?

but you see, the adapter kit is not the problem. finding the carburetor is. does anyone know how i can source the Weber carb that fits the kit? not sure what car it can be sourced from.

Bad news - Weber's out of business

After a prolonged strike, Weber went bankrupt or whatever they call it in Italy. A US company did buy the rights to some of their designs but I hear the prices they are proposing are a real shock.

I amy reposting this text pulled from a BMW forum. "weber closed shop in '04. southern carbs and injection (uk) is now making dcow's (dcoe) but the price is so steep. so you way want to hang on to your webers. <snip> as far as side drafts Solex (Italy or Germany), Dellorto, Mikuni and SK are the other options jets and gaskets are still available for those carbs"

Sooo... grab any Weber hardware you can find and lock it away because it's going to be real scarce. Time to look for alternatives. I know the Motorcraft 2100 will work on AMC 258 inline sixes, which also run well on a properly jetted 32/36 DGV or 38/38 DGAS. So it's time to get creative.

I sold all my weber stuff on ebay,including two of those weber books published in the 60's.they are the definitive work on webers,you can surf the web for years and never find the same quality of info.In fact I've seen a lot of stuff in various sites that was plagiarised from them.
But ,you will never find a weber to fit the M110 engine,they never ever made a spread bore 4 barrell like the solex.
There was however a kit for the m115 engine which used a solex side draft single barrell and swapped in a common weber progressive two barrel carb.
Go for the holley!!,as vanir said,just pull the manifold and get any competant machine shop to fit your carb.it's been done here in OZ thousands of times .I have had a few 280's with the holley set up.Or buy am edelbrock,you will find that if you contact edelbrock they will have info as to setting up the carb,which i think they do for you any way.
Side draft DCOE's would look great and can be set up by any weber specialist ,but at 300-500 dollars each second hand you had better be prepared to spend[}:)]

Carbs Unlimited still has the weber carb at a price of $695.00. I had my solex rebuildt 6 months ago at a cost of close to $300.00 and it is already leaking fuel like a sieve on my 1973 280C. You can put an adapter plate on and use a rochester 2 barrel but you have to set it up for a manual choke and it usually runs too rich and mucks up your plugs. Joe Johnson
