As an  amendment to my original question about fuel mileage in winter: for 
a Corvair,  what sort of difference does it make whether or not one opens 
and uses the  winter/summer opening in the lower shroud.  The '65 owners 
manual says to  open the slot at 60* F and lower temps.  Thoughts?

When new (and almost new) my LMs benefitted from following the owner's  
manual advice about the "winter/summer" plate.  Cold weather engine warmup,  
initial driveability and mileage benefitted from uncovering the opening on the 
 driver's side as recommended by the manual.  I still do it, but no longer  
take note of mileage differences.  Here in Maryland I typically  change the 
plate at Thanksgiving and in mid March.
