Weber twin 40 advice

[haggler]

Hi i have a set of weber twin 40 DCOE'S taken from a strada 130 abarth which i am gonig to fit to my standard 131 sport. Does anyone know if these carbs will need re jetting. Also where does the fuel return pipe go or do you block it off.

What size engine did they come off and what size engine are they going on? Was the donor engine stock or modified?

I blocked my return pipe off.
I advise a pressure regulator.
I fitted a pair of 45's so cant advise about the jets.

As far as i know he strada was a 2ltr standard 2 ltr twincam. My car is also a 2ltr twincam.

Should be pretty close. I think the Strada 130 engine had slightly different cams, but the standard jets will be close enough to get it running. It is always better to get it set up properly on a rolling road this will verify everything is correct.

They are more than enough, the strada 131tc was more highly tuned that the 131 , if you can get get the cams as well fot them thry are higher lift than the sport...
