	My 79 Spider and my 73 Montreal both do this, it's the result of
running a rich fuel mixture in the cylinder as is normal for all Alfas.
During deceleration the fuel mixture is not completely burned so it
combusts in the exhaust.  Relax, that's one of the things I really dig
about these cars, it scares the shit out of the competition (other
non-Alfa vehicles) and intimidates the civilians.  Ever see the Porsche
935's on the race track?  They have a similar effect during deceleration
around corners, they have a little flame shooting out of the tail pipe.
I've been told that my Montreal does the same thing, I've never seen it,
I'm always driving.  I think it's cool as hell that it does that.  Ciao!
