<div class="ubbcode-block"><div class="ubbcode-header">Quote:]The big question I have on this is, what good is one sensor on a car with two carbs. [/QUOTE]
Bill,
That is probably a valid question. I can only answer for having three carbs and the end result. My NGK sensor is down in the header collector, so I definitely get an "average" of the three carbs.
So where does one begin? You have to have a running engine to tune it, so I started by bottoming out my adjustments and worked backwards from a standard "rule of thumb" middle position to tweak mine in. Without doing that, I don't know how anyone could ever get any car with multiple carbs to run and then tune it.
The sensor that I have installed is extremely sensitive and pics up the slightest variation in change either richer or leaner. By having it and not relying upon the ear method, I was able to bring mine into a smooth running and better performing state.
Is there a better way to install or do this? There probably is, but for my wants and needs, this is just fine. Someday if someone writes it up and shows me, I may move in that direction, but for now, this will do nicely.
I don't disagree with you, I just don't know how else to answer you.
