I have a few sets of 45 dellortos . I’m interested which 914 engine needs 48 idf. Carbs .
45 dellortos have 38 Venturi . This would need to be 2.4 liter or more
Check DPR fir your crank
So, the current motor is a 2056 that I spin to 7500 RPM. The next gen motor I'm building will be a 2270 that spins at least to 7000 RPM. I currently have an aftermarket 36mm venturi in 40 Dells.
https://www.csp-shop.com/en/enginetech/carb...alculation.htmlBoth of those engines show needing a 40mm venturi. I double checked with CB too.
