I was surprised…. It only required , minor, adjusting with the electric choke setting and the high idol…. Which is located on the opposite side of the regular idle screw.. This would be standard adjustments required on any new carburetor… I also believe they have contact information to help you solve these minor issues - if they arise…… take a deep breath and ask grandpa to help……. Or the neighbor …. Review: Does what you think it will do - First things first, I put this on my 350 sbc and it ran without adjustment. Did its job. I wanted to finish restoring my truck, so it sat waiting repairs/upgrades. Admittedly, I could have prepped the carb for a couple month hiatus while I spruced up on the interior. Regardless I took the carb apart and cleaned the irresponsibilities out before trying to start and tune this damn truck for the final time. Now I’m not the best hot rod mechanic this side of the Mississippi, but I know a q-jet like I know Riley Reid. This mf looks great, but the material quality is dogwater. The accelerator pump rubber is probably rubber cement glue molded to look like a seal. There is no corrosion inhibitors on anything so why use it. And the choke pull-off. The choke pull-off stopped working on my way-too-big cammed 1970 something goodwrench truck crate motor and it flooded my engine after a 3 start cycles and trying to time my engine. I did this for 4 days and the same thing happened. It was fine for the first few starts and I can’t start the thing. Did I mention my cam is too big? Anyways after rebuilding everything around this carb I just rebuilt the original q-jet that came with the truck and it runs great. TLDR this carb is a great plug and play, but it shouldn’t sit at all after it’s been through a heat cycle. ## Features - Replace : This is brand new 4-BBL carburetor from THUNDERMINGO can directly Replace For 1904R 1906R Rochester Quadrajet 4MV electric choke 4-BBL carburetor.

I knew right away as I pulled it out the box it was a bad carb. Its basically a Rochester Quadrajet rip off. I should have just bought a real rebuilt Rochester off of JEGS or Summit. Do not buy this carb for all you car guys out there I know the price looks good but the quality just isn't there. ## Frequently Bought Together - 4 Barrel Carburetor for Rochester Quadrajet Carburetor 4MV 1904R 1906R 4BBL Carb Fits for Chevy Chevrolet 305 350 c.i Engine V8 GM Cadillac 1980-1989 Vacuum Secondary 750 CFM New with Electric Choke - Pindex Carburetor Gaskets 1932 4-Barrel to 4-Barrel Carburetor Gasket Kit - FEL-PRO MS 90314-2 Engine Intake Manifold Gasket Set for Chevrolet Camaro --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/414570215-rochester-quadrajet-carburetor-new-4-barrel-quadrajet-carburetor-1904r-1906r](https://www.desertcart.tn/products/414570215-rochester-quadrajet-carburetor-new-4-barrel-quadrajet-carburetor-1904r-1906r) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-10-26*
