At the risk of covering the same ground as the responses to 350mrh's posting, I am still experiencing a stumble during acceleration. Not from a stand still and not while moving at a decent speed. This is only present right around 1100 to 1200 rpm...I've adjusted the accelerator pump in all three positions; I've gone with full manifold vacuum as well as ported vacuum and again, no affect. Advanced and retarded the timing (currently on 6deg). Seems to be carb related. In my younger days I learned that bigger isn't always better with regard to jets on a Holley. Could this be the same phenomenon - oh this is an Edelbrock carb. It's new...and I have only recently bought the truck so I know no history. Thanks in advance for your input / advise. Kelly
