Aeroflow 650 CFM 4-Barrel Double Pumper Carburettor with Electric Choke

Designed for street and strip action, this Aeroflow 650 CFM 4-Barrel Carburettor pushes beyond mild street performance. Featuring a square bore 4150 flange and an electric choke, it delivers reliable starts and immediate throttle response. The double-pumper design employs two accelerator pumps to deliver fuel quickly when you need it most, while mechanical secondaries ensure solid power delivery under load. Crafted from lightweight diecast aluminium with a sleek silver finish, it blends head-turning style with real performance.

Precision tuning is built in. Four-corner idle adjustment and screw-in air bleeds allow you to dial in idle quality and air-fuel mixture for your engine. Dual inlet fuel bowls with sight glass windows make float adjustments quick and safe, so you can monitor fuel levels at a glance. It’s a bolt-on, run-ready solution that’s easy to tune for smooth throttle response across the power band. Available in 600 to 750 CFM to match your engine needs.
