Holley carbs. Love'em or hate'em?
Holley's need three basic things to keep them bullet proof.
1. A good air cleaner with a carb to aircleaner seal , keeps the air bleeds from getting dirt in them and messing up the idle.
2. A good fuel filter , I run a large one before the fuel pump and an inline one between the regulator and the carb.
3. A bottle of gumout thrown in the gas tank every month or so
