Stumped and Frustrated with a Holley 670 Hesitation

With that black spring in the secondary,, they prob shouldn't have been opening till 3500-4000 rpm,, when was your hesitation,, did it change rpm with the different springs..??

Also, if your accel pump is adjusted way too far,, you may be getting a short squirt, cuz its only getting 1/2 a "pump".. adjust accel lever till it just touches the pump arm and takes out any slack....
