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! |

See the following for a formula on cylinder volume vs. rpm vs. venturi.
http://www.performanceoriented.com/throttl...-venturi-sizing My guess is you would want a 40mm venturi, so a 48mm IDF or DRLA. |
