<VV> Bad smell

[Ewell Mills]

I have two Corvairs and both of them have a really bad smell when I first
start them (in garage with door open).  It seems to be the exhaust, not a
gasoline smell (I cured that when I went to an electric fuel pump).  I owned a
60 model in 1960 and do not recall it smelling that way.  (I did not have a
garage back then).  Is it possibly caused by using unleaded gas?  The smell
seems to go away after the car is warmed up.  Any ideas, or am I the only one
with this problem.  My other cars all have catalytic converters and don't
exhibit this.
