Wideband works great
I got the O2 sensor installed just downstream of the header collector. Connected the gauge, and within a few minutes I had the carb idling best yet, 11hg of vacuum, and 13.75ish AFR. I took the car for the first drive out of the neighborhood and put about 10 miles on it. Woohoo
I also had to raise the primary fuel bowl level a hair and lower the secondary fuel bowl level a good bit. (The car/carb was level when adjusting)
I still have the occasional exhaust pop/backfire and some engine run on when shutting down.
I'll take some AFR readings while driving soon.
The wideband makes a huge difference in tuning ability.
