Holley carbutretor question
I have a 700 holley double pumper on a 351w. Can't get it to idle down. Secondary throttle plates don't close all the way. At idle I can cover the primaries with my hand and it still runs. Cover the secondaries and it quits. Set screw for the secondaries is backed off so its not that. Is it worth a rebuild or is their an easy fix? Should I just replace it with a 670 Holley Street Avenger? Thanks Jim
