We are converting a stock 2 liter 4 cyl from D jet to Webers. My gut is telling me a 40 IDF with 32mm venturis is the correct starting point. I am considering purchase of a complete set of 44 IDF's, but are unable to locate 32 mm venturis. Assuming 32MM venturis can be found are 44 IDF"s too large for a stock 2 liter?
thank you |

Question: is the diameter air the manifold interface different between the 2 ?
If the carb throat is larger than the manifold port size, a restriction is formed at that shoulder. Carb base diameter should match the manifold throat size. |
