Here's A Step-By-Step Rebuild Tour Through A Typical Holley Vacuum-Secondary Four-Barrel Carburetor
If there is an icon in the performance world, it has to be the Holley four-barrel carburetor.

Better yet, its modular design makes the Holley exceptionally easy to work on. Basically, if you can fog a mirror, you can rebuild a Holley. Given that, we’ve assembled a step-by-step rebuild tour through a typical Holley vacuum-secondary four-barrel carburetor. So grab your wrenches and screwdrivers and let’s get started. Oh, don’t forget the fender covers.
