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! |

Thank you for the responses.
Guidance on this seems to be all over the map, but I think I’m more concerned about giving it too much carb rather than not enough. I’d rather have good off idle behavior and what worries me about the 48s is they may ultimately produce more power but it’s at a RPM that all rarely be at in a streetcar. I assume that’s behind your suggestion Mark Henry? Great resource @yeahmag |
