Replacing the Accelerator Pump Cam on a Holley Carburetor

I&running into a carb backfire issue due to not having a smooth enough fuel delivery by the accelerator pump. I&bringing the carburetor back to mostly stock to start tuning from a known baseline. In this video I&replacing the green cam on the primary back to the pink cam which I believe originally came with the carburetor. The next video I&cover replacement of the accelerator pump nozzles / squirters. As an Amazon Associate I earn from qualifying purchases. Subscribe to the channel! #1969Mustang #holley #carb
