Rebuild solex fintail carbs - advise wanted

[ScooterABC]

Hi have a 1963 220S (and a 1960 220S) that both seem to have the same pair of Solex carbs. I can't identify the carbs other than inside one of the barrels I can see 32 23. Which I assume is the diameters of the barrels.

I realize that this is a stupid question but can someone point me to the correct rebuild kits for these carbs? The 1963 is a car that was parked for 10 years that I have brought back to life. It runs pretty well except it clearly lacks the accelerator pump functionality that it should have. The 1960 is a parts car, but oddly enough the engine on that car runs pretty well too.

I'm assuming the carbs are the same between 1960 and 1963, although that is based on observation. I thought that I had read that earlier cars had smaller carbs... Anyway, pictures attached of both sets...

The 1960 carbs look a little nicer only because it seems that someone spray painted them silver...

Once you identify your carb model (I think it's the 32 PDSIT), check out these guys. They have just about everything.

The shop manual from that era says your car came equipped with two 32 PAITA. Of course someone could have changed them out over the years.

Mercedes list the accel pump number for these as #841.

I can't be anymore help than this since most of my stuff from that year is limited to the Mechanical Fuel Injection service.

Note that the specs are a bit different for the front carb than from the rear. Different sized tubes and such.

This might be a good place to look around if you do have the original carbs.

I got kits for the 32 PAITA from the Carburetor Refactory in Richmond, CA

You will most likely be getting Royze kits so you might save a little by buying direct from them. These carbs are very easy to rebuild. Just make sure that you get the fuel enrichment valves positioned correctly or you will go crazy trying to get the idle and "choke" right.

Thanks all, I ordered the kits on ebay. Price was better than anywhere else. I understand that the bellows for the dash pot is not included and have read a few suggestions for replacement. Is this important?
