Description of Holley Quick Fuel Brawler Carburetor 650 CFM 4150 Electric Choke Mechanical Secondaries 4 Barrel

Brand New Quick Fuel 650 CFM Brawler Diecast Carburetor with Mechanical Secondaries, Electric Choke, 4150 Model (Part #BR-67255). Features: Dual inlet fuel bowls with sight glass windows for safe and easy float adjustments | Electric choke for easy starting in colder climates. Brawler diecast 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. Do not 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. Brawlers come with the latest technology in air/fuel calibrations for current day street engine demands. The Brawler family of diecast carburetors are all made from light-weight diecast aluminum components and are available in both vacuum and mechanical secondary models. They offer all the tunability and options that you would find from more expensive carburetors in the market, including a beautiful appearance, electric choke, and four-corner idle adjustment on all mechanical secondary models. 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.

Excellent product for carburetor

Excellent product. Much nicer than the old Holley carburetors I'm used to. Permanent sight glasses make adjusting the fuel level clean and easy

Pros
  • carburetor and parts
Cons
  • The list will be long.

Works right out of the box. And yes, it's Holly. Swamps when you first strike. But probably because I have a high intake. Need fine tuning. But what do you expect.

Pros
  • Fuel System
Cons
  • Operating Speed

Not like before

This Holley carburetor was fitted to a Ford 460 with big block construction. The electric throttle took quite a long time to set up and adjust. Was far from the box. Finally it works much better. It is also very sensitive to fuel pressure. I think I prefer the Holley Street Demon because they are easier to set up and easier to manage.

Pros
  • Automobile
Cons
  • Blank
