[Mgs] [MGS] Air Cleaners

[Schauss, Peter (IT Solutions)]

I have been running the K&N filters on my 1980 B with HS4's for at least
5 years.  I did have a slight miss at highway speeds shortly after I
made the conversion.  It turned out that the needles which came with my
HS4's were not the correct ones, probably too lean.  Replacing them with
stock needles solved the problem.

Has anyone had any experiance with the airflow charictaristics of the
K&N
tapered air filters
used on the dual SU changeover on late model B's ?  They seem to be the
only
after market filters
avalible with the clearances needed for this set-up.  The  filter  is
only
about an inch and a quarter
thick and  the outer cover is about half the size of the base. The
airflow
thru the filter is almost
straight into the carb throat. I am sure that a (very) short venturi
would
help. However, for clearance purposes,
one base has the mounting and air hole offset to the limit to the bottom
of
the base. The inside edge of the filter
is at the edge of the air hole and because of the filter taper and
thickness
and mounting there is no room
for a venturi.  The car runs fine with no filters on but has a "search"
atitude at highway speed with the
filters in place. Partial taping of the filter area to change the
airflow
seems to cure this.
I know this sounds like a mixture/ needle problem but I have not been
able
to address this yet as I have a
new distribitor to install first. No, I don't think it is ignition
related,
just looking for experiances with these
filters.
