I advise a pressure regulator. I fitted a pair of 45's so cant advise about the jets. Steve Title: Re: Weber twin 40 advice Post by: haggler on February 08, 2009, 03:15:49 PM As far as i know he strada was a 2ltr standard 2 ltr twincam. My car is also a 2ltr twincam.

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.
