Now that the milder 2056 is in the car, I could use some advice on carb tune.
compression is at 8.8:1, valves are 44/38, cam is Webcam 86a. Weber IDF 40's have 37mm venturis, 135 mains airjets 200 F11 emulsion tube I am told by the builder that I should step down to 34 venturis, but, have no idea where else to start. Car will go to a good tuner soon enough, just want o have a good starting point. |

Pierce manifolds is my go to for all weber parts. I'm pretty sure i have 32s. You can try them out. If you want to use them then buy me a replacement and have them shipped to me.
