 Thanks for input. I think my first step needs to be verifying that those A/F readings are real. I have read that even a very small leak in the exhaust can skew readings to lean. Seems strange that I went from basically OK to seriously lean with a pretty small change in jets. I'll make sure no leaks then take somewhere to get A/F verified. The Innovate meter required a calibration in air - the new A/F gauge has the "feature" that no calibration is required. Maybe I am being paranoid, but if 17.5:1 is a real reading, isn't that enough to burn valves and melt pistons?

Any input from anybody about how steady an A/F meter should read?

Thanks
