Michael:
You might also check the diaphragm for holes, as a hole can make
the
slide sluggish, and the carb will run rich. Stretch the diaphragm while
holding
it up to the light to look for pinholes. But if you fuel pump were
malfunctioning,
both carbs would be rich, so the fuel pump theory seems unlikely.
After you try adjusting the mixture, if it is still rich, we can
discuss where to go
from there. Our cars have changed hands many times, and often these
issues are the result
of the DPO buggering something up. So there are many potential causes.
For now stick to
the easy ones, and worry about the subtle ones later.

Listers:
On one of my previous posts, I mentioned that I had gotten some advice
to
check the fuel pressure from my pump as part of the full checklist on
determining why my front carburetor runs rich. The idea was that the
fuel pump can
malfunction by pumping at too high a pressure.

I am still waiting for the mixture adjustment tool, which should arrive
in a
day or two. I thought I would go through everything methodically before
just leaning out the mixture.
Thanks.
