Why Rebuild Your Holley 4160?
-
Fix Fuel Leaks: Dried-out gaskets are the #1 cause of Holley fuel bowl leaks
-
Crisp Acceleration: A fresh accelerator pump diaphragm eliminates bog and hesitation
-
Proper Air-Fuel Ratio: Replace the power valve to restore correct enrichment under load
-
Prevent Flooding: Worn needle and seat assemblies cause flooding and hard hot starts
