Hi all. On my '55 Sprint I have these carbs. I believe they are named SOLEX 32 PAIAT. But I can't find any drawings or instructions of them on the internet. Can anyone help? Thank you.
I might have a spare PAIAT carburettor for you - will look in my boxes.
Hi ThierryHi Toom356,
The Fispa fuel filter you show in post # 1 is certainly not original for the 1955 cars.
If there was one in your car, it would have been the earlier Fispa type: FB 37
Is an original air cleaner able to be used on your Weber, or is it way off size-wise to fit without air gaps? I’ve read about some type of adapter, but I don’t want to destroy my original can.My $0.02. I spent a bit of time and money to keep the original Solex on my '64 Giulia Spider and it never performed to my liking. I borrowed a Weber DCD from a friend's 1300cc Sprint and it worked better without jetting changes on my 1600 than my Solex . So, I bought a DCD (a period upgrade), rebuilt it, and it has been fantastic (after easy rebuild). If you want to keep originality, keep the Solex. If you want ease of tuning, parts, etc, I found the DCD to be a great improvement. The mechanical secondary gives physical right-foot-"Turbo!" feedback. You can even go modern Weber DGV for pretty reasonable money. I am running a DCD 32/36 on the Solex 32/32 intake which I think you have. That's not a theoretically deal setup, but it is working very well.
My Porsche 356A T2s for sure feels much more sportier than the Sprint (though I only have very limited experience with the Sprint for comparison). But needs to be challenged in the future.Is an original air cleaner able to be used on your Weber, or is it way off size-wise to fit without air gaps?

So far I have not felt a great response from any Solex I’ve been experimenting with, including my original, which is still out being restored after its first rebuild didn’t work at all. I’m also an originality-dedicated owner, but not against an upgrade that makes my Spider a better driving experience.
I know it’s not supposed to feel like a V-8 being only a 1300, but my 356 T5 didn’t have a V-8 either and it actually responded with true intent when you hit the pedal like this car can only dream about. I wish I could drive another Giulietta just to see if there’s a true first gear difference with its typical Normale diff gearing, or if that’s “just the way it is”… A good Weber is sounding much more promising. How much tinkering needs done with the linkage to the pedal?
My car came with an adapter to fit the stock air filter onto a Weber (AlfaStop used to carry them) but it never fit correctly and was too tall. Adding a Weber to a 1600 means using a smaller air filter. A 1300 is easier fitment because of the shorter engine. I'm using a pancake filter as shown in the picture.Is an original air cleaner able to be used on your Weber, or is it way off size-wise to fit without air gaps?
