My apologies for not responding to the requests for more information sooner -- I've literally been working around the clock this week trying to meet a deadline, so I haven't had time to give Mike a call to discuss this. My understanding is that running A/F ratios in the mid to high 14:1 range at idle and under light loads is not an issue. It is somewhat concerning that my ratio is north of that, but this may be attributable to using a sniffer. I appreciate all the sharp eyes and minds on the forum looking out for each other.
With all of the knowledge and experience that Jeremy has, I'm sure there's a good explanation for this. I've emailed Mike asking him to address these concerns first-hand in this thread, so we're all on the same page.
