If you are just running off the vacuum tank, I'd suspect the needle and seat need replacement, or the float is mis-adjusted or has a leak. If you're running off a direct-feed electric pump, the pressure is too high; the DL is meant to operate on the gas feed pressure of the gravity head from the S-W taml to the carb, an electric pump will overwhelm it. There's a pretty informative thread over on AACA forums about the issues of using an electric pump with updraft carbs designed to feed off vacuum fuel tanks.
