A couple of comments Bruce: I have an Innovate brand wide band oxygen sensor in my opinion you need a similar tool to correctly tune a carb. Even a single barrel Carter or Holley can be leaned out I think, although I have not yet tuned a single barrel carb with it. You will need an oxygen sensor bung welded in the exhaust pipe a few inches below the exhaust manifold. A blind plug comes with the unit or you can plug the hole with a 14mm spark plug when you are not using the unit. Very lean mixtures are OK in most engines at average highway power. You just don't want to be overly lean when you are making max power. The other comment you made about an economy run sounds like fun, but I would suggest that it be combined with a rally so that participants would have to meet some performance for timed distances or time intervals and still get the best mileage. That wold be fun and it could be a way to involve our better halves or close friends because a two-person crew could be required and it is not allout racing.
