I have a stock 350 with a Holley 750 double pumper (not my idea). It's secondaries have been flooding out for no reason. Sometimes if I clean it out real goo it quits but then it just goes back to flooding out. I don't know if its doing that just because my carb is too big for my engine or what. Any help is appreciated thanks!

IMHO, the 750 may be just a tad big, but it still shouldn't flood. I would start by double checking the level that the floats are set at. They may be too high causing the fuel not to shut off properly. Beyond that, chack the needle and seat to make sure they are clean and sealing properly. Finally (or first, because it's probably easiest) make sure your fuel pressure isn't too high. I don't have the spec right with me but if it's too high, the carb can't shut off the flow.
