Carb problems again!

[winslow33]

I think I'm having problems with the old holley 750 on my chevy 350... She idles like a champ, and I can get it to rev up slow to redline, but if i quickly punch the accelerator to the floor (Especially in gear), the car will just die.. :x

Sounds like a bad accelator pump. Was the carb apart recently? If so check the bowel gasket,it has to have the hole lined up with the accelator pump passage. Another thing to check is if the pump cam is still in place, check the pump override spring as well.
