As far as I am concerned, this sums up my feelings about CIS vs Carbs.
1) The guys with working CIS systems are probably out driving their cars so they won't reply.
2) The guys that tinker with their CIS systems and have them royally screwed up will keep you running in circles with suggestions.
3) The guys that have spent a fortune on Webers will tell you they're great to justify their expenditure to themselves.
Also be aware I have two early 70’s cars with carbs. They do not approach CIS for starting and drivability.

Haha, this is funny. I'm definitely in the number 1 camp! Had my SC for 15 years now. After engine refresh, CIS parts were just checked and lightly cleaned and refitted to a new airbox ( which is now made of stiffer PA6, not ABS ). Not a single issue in 60,000 miles. No surges, no hiccups, hot or cold. Starts on the button.
Now my Alfa on the other had with it's twin Dellortos. Well, starting it is like trying to wake up a surly teenager. Once you're running it's ok - until it stalls at a junction - or idles at 2000 RPM, or spits flames in your face. It does make a great sound though!
