WB - maybe that is the problem. I was assuming I needed to be as close to 14.7. as possible to make most HP. Perhaps that is not the case? Like I said, the car sees to drive fine, but hard to tell performance-wise, (which is why i was asking about dyno tuning in another thread). When the richness was really bad - 10ish all the time, i was getting black plugs. plugs now are much cleaner on strap, ring around the edge still has some minor black depending on cylinder. I did move up a spark plug in heat. so maybe I should stop fixating on 14.7?
