Carb issue

Alrighty, A little while ago while driving my 67 ss396 with a 750 holley (vac secondary), I noticed a "rough spot" in the mid rpm range. It was barley perceptable but like most I know my car pretty well and I could notice it. Anyways, I decided to fish around trying to find a culprit. I checked the fuel bowl float level and noticed it was a bit low, so I readjusted the floats so that fuel would barely dribble out of the sight plug. The gaskets for the float adjustment were pretty bad, and when I tightened everything back down, the primary fuel bowl adjustment gasket leaked a little, not bad, but it did leak. So I took the car back out, and the problem got worse. Now the car will barely accelerate, and when I punch the gas the car almost dies. The accelerator pump shoots out just fine when the throttle linkage is operated. Could the stumble be caused by low fuel pressure in the primary fuel bowl (from the leaking gasket)?

A carb rebuild is in order anways, just looking for some thoughts.
