Dear fellow enthusiasts

I have now removed the Weber carburettors from my Urraco P250 s from 1973.
I have read in all the information about urraco that it is equipped with 40mm IDF Webers..
We didn't find any info on the carburettors other than it is Italian webers, but compared to another IDF Weber i have the once on the urraco is smaller!! Seems like it is 38 or 36mm Webers instead of 40mm.. Why is that? Anybody know? It ceartainly looks like the carburettors have been on the car all the time.


Cheers
Daniel
