Has anyone rigged up an O2 sensor on their carbureted LUV with a meter for determining the air/fuel mixture? I know that they are sold as kits at parts stores. If so, did this modification help you to get through the emissions tests any easier.?

Yeah I have one on my truck. Welded the bone for the sensor just below the manifold joint.

Well I didn't have any issues with smog before I put it in so no it didn't help me. And the smog tech didn't pay any attention to it.

Did it help in adjusting your carb to best burn?.....Or was the carb too worn out to be correctly calibrated to achieve best burn? I have a fairly new factory carb and I can't get it to burn 'clean'. Did the 02 sensor and gage work out?

Yeah, I suppose. I was able to Target real close to stoich at idle. And verify that it wasn't too rich or lean @WOT.
It also helps me realize that I was having vacuum leaks and other issues, because I noticed the AFR would randomly change from what I normally was. (Carb was actually vibrating loose despite being lock-tited)

No my carburetor was actually almost new, a Weber 32/36.

It's a factory dash.
I threw in that little tack not long after I bought the truck just to know what kind of RPMs I'm running down the highway or down the trail.
I just had some gauges left over from previous vehicles (act, egt, and vacuum/boost) and then when I had the engine rebuilt I added actual water temp, oil temp, and oil pressure gauges.
