Helpful thanks Don. Checked my carb parts box, as luck would have it probably have all or most of what's needed to rebuild / refresh the DCNFs. Good info on the emulsion tubes. Also, my chokes are 30mmI could never get the transition region to work well with F25 emulsion tubes. I'm currently using F36 tubes and I've heard that F24 tubes also work well for this application. Probably best to get the carbs cleaned up and in working order before swapping parts. I'm currently running 50 idles, 130 mains, 220 air correctors.
Also, measured the distance between carbs on the Alquati vs. the Abarth intake manifolds. The Alquati places the DCNFs 26mm further apart, which does not permit use of the aforementioned repro linkage.
