I inspected it, it is the stock one should I upgrade it with the better one edelbrock makes? I tried moving the slots on slot made it worse the other just about the same
under the hood with the engine off, what happens when you push on the linkage- like you are pressing on the pedal. you should get gas out of the accelerator nozzle in the carb right away.
I had a 750 cfm that I replaced the plunger in the carb during a rebuild and it would hesitate every time, took me a minute to figure it out, but the 650s and the 750s have a different plunger. More than likley hopefully not your problem but you never know.
