Re: Any Edelbrock Carburetor experts? Trying my hand at tuning

The mixture screws won't show you anything on the plugs. They're for the idle circuit. They don't have anything to do with the jets(power circuit).
Reading plugs is best done after a full throttle blast with power cut then plugs pulled for a look.
