Holley Brawler Double-Pumper Carburetor Installation and Basic Tuning

These days, the talk seems to be all about EFI and fuel injection retrofit kits. Dalton at Pole Barn Garage wonders where all the love is classic double pumpers?

Dalton demonstrates just how simple and easy a carburetor can make your life — bolt one on, make a few connections and simple adjustments, and you immediately get excellent throttle response and performance.

Marvel at the beauty of a carburetor in its natural habitat — onboard a large displacement American V8, this one under the hood of the Holey Goat 1970 Pontiac GTO.

Holley Brawler Installation and Basic Tuning

Here’s a quick “how-to” that covers installing a new Holley Brawler double-pumper carburetor. The full Installation Instructions appear below.

Tech Note: This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with 5 3/16″ x 5 5/8″ bolt pattern. If you have a spreadbore style intake manifold, you will need an adapter to install this carburetor. Similar to the Mr. Gasket #1932.
