Fuel pressure reactions

Wideband O2 sensors are dropping in price. I am trying to work them into all my old cars (except my diesels). It is hard to really know what a carb is doing without one.


I have one in the car. I wouldn't have it any other way. It is such an invaluable tool for tuning.

I finally took the car for a ride the afternoon, all is well. Except for half throttle. It seems a little lean. But WOT looks a little fat. Going to the dyno tomorrow :)
