Yes, elevation will make a bit of a difference. How much I'm not sure of, but basically the air ghets thinner (less dense) as you go up, so in theory you can lower the needle/raise the clip to run a little leaner (less fuel to mix with the thinner air). Once you mix in air temperature, then you have more 'tuning' of the air/fuel mix to think about since colder air is denser, so more O2 per stroke going in.


Any day that starts with a good ride is already a better day, and a bad day riding still beats a good day working.
