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]
