Features

  • 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.

  • Holley quality
Love the glass ports on the fuel bowls. Should come with return throttle linkage! Works so much better with it. Fast idle bolt much easier to get to. Great mechanical secondaries. Runs a little leaner than the 670 it replaced. What happened to the larger vacuum port on front? Needed reducer to connect to 3/8 PVC hose. All around great carb ... show more

  • DEFECTIVE!
This product was bought in October 13th of 2023 for a brand new rebuilt motor. Upon arrival on the 18th, I noticed the secondary fuel bowl looked odd. The whole carburetor has a shiny finish, whilst the secondary bowl did not. It looked like a replacement, poorly cast part. Winter came, so we didn’t fool with it much. Come feb 5 of 2024 I try to start the car, it starts, however the secondary fuel bowl profusely starts leaking at the fuel feed inlet. Upon further inspection, the surface is not flush, and looks like it has pieces of metal missing. I called southwest speedshop, to which they explained to me that they weren't the sellers. After digging deeper I found out someone duped their add?? Whatever that means? And that they’re basically not at fault. They redirected me to Holley, saying it should be covered. I call them and told them what was up. To sum it up, I have to buy a new bowl for this carburetor. Absolutely bs. ... show more

  • Fast delivery!
Carb showed up in two days however……finish on this thing is not what I expected given the brand and cost. Scratches and imperfections are all over this thing. I’m very disappointed as this was supposed to be installed on a 1969 c10 short bed show truck. I will not be using this on my build. Zero quality control. Looks like it was tossed around a garage and then thrown in a box. ... show more

  • Part of the item was broke
Carburetor runs and works great but the choke housing cap was shattered when I opened the package, luckily I had an extra that fit. The plastic cap was broken due to poor packaging. 2.5 ⭐️
