holley idle issues
Mostly on older carbs where someone cranks down the baseplate too hard. It warps the base and the throttle shaft bores start to wear really fast. They can be rebushed or you can just replace the base with one these really nice billet units from QuickFuel. They have a secondary idle adjustment on the top for easy tuning, come with three linkages (super progressive, progressive and 1:1), are much stronger, etc.
