I have the 82751 holley and have been having issues with off-idle stumble. We tuned at the track and just couldn't get it dialed in. So decided to pull it apart and inspect everything just to be sure. I noticed I have 3 different sized air bleeds, 71, 35 or 6 the bottom of the number is gone, and 4 of a 22 or 25 sized ones. Is this normal? I haven't found the specs for this carb to verify thats what came with it. Anyone else running this carb?
