Ferrari Mailing List: Re: Carb 308 ignition timing

Thanks Rick.

All the anti-pollution gear is removed. It was just a point of reference. So
it doesn't seem to MIND the 12deg....and if it's not uncommon, then I'm
worrying about nothing.

   Peter, my MGB is timed at 10 degrees BTDC at 600rpm idle and can advance
as much as 20 degrees under operating conditions.
   In your line, "they've set it up at 12deg BTDC. I know usually it's 5deg
or so, and the aussie spec pollution requirement is actually 1-2deg ATDC."
is interesting.  My MG idles at 10 degrees BTDC with the vacuum advance
operating so that much advance is not uncommon.  HOWEVER, the retarded spark
may be a little 'greener'.  I'm guessing here but what other reason might
there be for, "...and the aussie spec pollution requirement is actually
1-2deg ATDC."  If you have to pass an emissions test you may have to retard
the spark to pass then reset it to operating condition. 
Here in Houston we have all kinds of emissions tests BUT there are no tests
for antiques - defined as 25 years and older.
   Good luck.
