ya that does make sense, if you have more air you would need more fuel to have a good a/f ratio.
but the guy that tuned it, after i told him i was at sea level says "With the altitude being so different you will need to lean out the high speed needle since there is more oxygen in the air when you are at sea level"
i dunno? sounds like i have some playing to do tomorrow
