Main 165
Main air 180

Pump jet .5
Pump exhaust .6 to .8

You may not agree but....
Well, I am always willing to experiment and improve engine response with the webers.
Do you have this setup in your car or is this experience setting up Ford BB's with Webers?
A 75 idle jet with the 120 idle air (which is what I had in my jets box) worked very well, no more sneezing out the carb and idle mixture quite close to ideal A/F ratio. Before going on and purchasing any extra jets I would like to know how you arrived at the above settings.
Thanks
