On my Sprite I would turn the mixture nut up two turns at altitude and all 
was good.  Last day of vacation, headed "downhill", two turns richer and all 
was back to normal.  With the Megasquirt fuel injuection, the built in MAP 
sensor adjusts the mixture based on ambient pressure and no need to even 
think about it.  For LotO, I crossed the Rockies and Sierra crests twice 
each with no loss of power and no re-tuning.  Carbs are simple and 
dependable, but some of this modern stuff is pretty cool too.
