RE: Setting CIS fuel mixture

["Aaron Ness" <aaron@makuta.com>]

It is a vacuum leak (you have a hole in the intake somewhere after the
airflow plate) but it doesn't seem to behave as one.  Are you saying that
sometimes the mixture doesn't change when you plug the hole?  That seems
kind of odd - it should be pulling in just a little extra air (whatever you
can fit through that little hole) when the plug is out, so the mixture
should get a little more rich when you plug it.

The plug was gone from my '84 when I got it, and it ran great, although I
never had the CO content checked, and I never plugged the hole.
