Brawler Street carburetors are machined and assembled by craftsman right here in the USA. These carburetors work hard just as their name implies- just raw bare knuckled performance that you can rely on. Don't let the budget-friendly price fool you, the Brawler development focused on the performance you want and not the pretty box that it comes in. Brawler Street carburetors come with black billet metering blocks with the latest technology in air/fuel calibrations for today's street or race engine demands. They also come with black billet throttle bodies for superior durability and throttle shaft stability. Brawler Street models offer all of the options and tunability that you would find from more expensive carburetors in the market, including an electric choke, a beautiful finish, and four-corner idle adjustment on all mechanical secondary models.
