Weber Carb Jetting

[pcar9119]

Can anyone tell me what jetting they have there Weber Carbs on a 3.0. I'm starting my project, and want to start at a good spot on the jetting. I'm looking for main jet setting and air jet setting. Thanks

Try 145 mains ,180 airs, f7 emulsion ,60 idel jets that will get you started.
Cheers Chuck ,also 34mm venturis
