Title: Weber 28/36 DCD on A112 Abarth 70HP engine in Fiat 850
Post by: douwew on January 11, 2020, 10:03:56 AM
Dear fellow enthousiasts!

I'm running a A112 Abarth 70HP engine in my Fiat 850 Berlina. Engine is completely stock (Original camshaft, head, etc).
I'm now running it with a Weber 30DIC, but i want to switch to a Weber 28/36 DCD. I've heard it should drive well for a street car.
I have two carbs to choose from a Weber 28/36 DCD 23 and a Weber 28/36 DCD 7. They ae the same exept for the venturi's and jets, but that's all changeable.
My guestion is: what venturi's, jets etc should i fit to accomodate my engine (stock a112 70hp)?
I need something to start with or rather hear from someone with experience what works well.
Please help me out, share your experience and knowledge.

Thanx!
