carb whistle

[Sean B <polecat2@xxxxxxxx>]

We put a used 360 in my friend's car today, with a freshly-rebuilt 
Thermoquad.  There is no ported vacuum line on this carb, so we hooked 
the distributor vacuum advance to a nipple on the carb base.  It now 
whistles until we give it the slightest amount of throttle.  The whistle 
will even stop when we just jiggle the throttle shaft on the carb.  When 
we unhook and plug it back up, the whistle goes away.  Any ideas?
Thanks,

Sean
