What's the fuel pressure? I had a 32/36 DGV on a Land-Rover, and had
problems with it running rich when the fuel pressure was too high. The
fuel inlet needle valve isn't very strongly pressed on the seat, and
more than 4 PSI or so is enough to push it open. I'm not sure where
the excess fuel ends up leaving the carb and joining the mixture. A
replacement fuel pressure regulator fixed that pretty easily.
