Here is a set of carbs that I recently stripped down completely and rebuilt. I’ve been rebuilding Solexes for years, these are the best I’ve ever found with little to no wear. All brass is polished, new gaskets, cad plated carb bodies along with all other hardware. They are as close to new as you will find.
Here is a great overview of these carburetors on Porsche 912 Anthology.
On eBay with a starting bid of $999.
