Hesitating Holley
If my Holley stumbles just off idle, how do you tell if it requires a pump cam change or a different shooter? I have already checked/adjusted the following:
-secondary throttle plates fully closed at idle, -vacuum checked, 18-20" at 1,000 rpm, -set primary mixture screws to achieve the 20", -set idle rpm to 1,000, -acc. pump arm gap set at .0010", -rejetted the primary side from 70's to 68's, -something I've forgotten in my frustration [img]/ubbthreads/images/icons/mad.gif[/img]
