Another  tid bit,
something of a shocker, what the target AFR graph for a typical  example. I
can't recall the exact numbers, but the highest it got was 13:1  ish and was
as low as 8 or 9:1 at idle! Fuel economy was "relatively" good  and fuel was
cheap anyway, so why not go for the max power AFR?
Good  thread.

Ah, yes. Despite being an "economy car", the Corvair was never designed to  
hit the magical 14.6 A/F ratio. It was always designed to run richer. Probably  
due to some fear of that old "debble" detonation and pre ignition. If in 
doubt  about this, see the GM engine test reports Clark's sells.
