Paul,
   I believe that carbs meter by ratio of volume and engines want the ratio
to be by mass. That is why 2 strokes especially need different jetting on
hot days. When I used to race motorcycles, we jetted three or four times a
day as the day warmed up and then later cooled down.

                                                Gary Wolf

Duh. Yes of course. That is why one must lean at altitude.

I stand corrected. Thanks.
