WOT carb cutting out.



here’s a video. Happens under load at wot. Seems like it’s not getting enough fuel. Starts to cut of and lose power and backfire. If I step off the gas and reapply it goes away. I’ve been through the whole carb. Cleaned it up. New jets, metering rods, step up springs. Replaced fuel pump, checked all the lines they look good. Don’t know what’s causing it to do this. Any help would be greatly appreciated. It’s an Edelbrock 600 com carb on a mild 318.
