Carburetor, Holley Brawler, 650 CFM 4150 Mechanical Secondary, Electric Choke

Universal 650-CFM Brawler Street 4150 Carburetor (Mechanical Secondaries) by Brawler®

650-CFM four-barrel with mechanical secondaries, dual-feed bowls and serviceable fuel metering.

This 650-CFM Brawler® 4150 four-barrel carburetor uses mechanical secondary throttles and dual-feed fuel bowls for a direct response to changing throttle demand. Its aluminum main body is fitted with adjustable fuel-bowl level controls and serviceable calibration passages, allowing the carburetor to be tuned for an engine’s camshaft, gearing and intake combination. The Street configuration includes an electric choke to assist cold starting and retains a street-oriented fuel calibration. The mechanical secondaries are intended for engines that can use an immediate increase in airflow under heavy throttle. Confirm choke power and linkage compatibility before installation.
