Air/ Fuel ratio Wideband on Carbed motor?

[GMR-PERFORMANCE]

Daytona twin tech makes a kit ( I use it every time I dyno tune) and you can go out and log with it.. so you can a more stable look at whats going on.. NB sensor can be used however when you drop the MV down in the low 900 range the sensor is way far to one end, however a WB is a slower reading sensor than a NB.. Another thing you can so is figure how much a jet swap is giving you and use the NB down to 14.0 and then calc out the rest.. EGT is another way to get the job done..
