If I feed the throttle in gently, the engine will pull cleanly and strongly throughout the rev range. However if I'm cruising and then stand on the throttle the engine literally dies in the arse.
It's a 350 Chev with an Edelbrock 600 cfm carb. I've just replaced a heavy float that was causing the carb to flood, and I was hoping that this might also sort out the problem I just described but no luck.
Accelerator pump maybe? It's currently set in the middle hole so I can move the arm up or down one hole to give it more or less of a squirt.
