I have a pair of good Weber 44 IDF carbs but thinking they may be too small for the 2.7l Type4 being rebuilt. Anyone have some coaching on carb sizing?
Edit - maybe up to a 2256? Thanks! |

The single cylinder chart still works. It's similar, if not the same as what is in the CB Superformance book for Dellortos and I've used the model many times. Granted, I'm not really after low end for my cars, but I drive them around town easily.
