Step-by-Step Quadrajet Reassembly
Вставка
- Опубліковано 23 лип 2024
- The step-by-step Quadrajet 704 carburetor rebuild is done, and Part 3 is the final video of the series.
In this video, I cover the complete assembly process including the carburetor body, jets, needle, and seat, adjusting the float level, power piston, air horn, metering rods, accelerator pump, and more.
As I mentioned in the previous two videos, the best source for Rochester Quadrajet parts and knowledge are quadrajetparts.com and quadrajetpower.com
They have every part you may need available and their prices are super reasonable, plus the quality of the parts they sell and the service they provide is second to none.
I hope you find this series helpful for your Quadrajet rebuilding efforts.
And for the record, I am a regular, self-taught DIY mechanic with average tools, so if I can rebuild Quadrajet carburetors, so can you!
Thank you for watching! 🙂👍🏻

The repairs and other work I do are for my own benefit and entertainment, and even though my videos may sound and appear to give technical how-to advice, that's not my intention.
Working on a vehicle is inherently dangerous. If you're not confident, qualified, or lack the tools to do the job correctly and safely, hire a licensed mechanic.

Thank you! I am rebuilding one for a marine application. I disassembled the carb and every single step you made will make my assembly much easier.
Thank you for watching! 😊👍🏻
you produce some excellent videos.. spending time explaining things, zooming in, and showing issues are just a few components that create your quality. I watched several when I owned a C3 and then traded for a 1970 C10 which happens to have a Quad on it and your help goes on!.. Thanks again.
Thank you, Paul, for taking the time to share those kind words which are sincerely appreciated. Enjoy your C10 😊👍🏻
Great video, I have done that with the secondary lockout lever a bunch of times. It's one of things I always double check when I put a quadrajet back together. You might wanna check your base plate screws. Sometimes when the secondary lockout lever gets stuck like that the base plate screws need to be retightened because the lever prevents the base plate screws from tightening all the way when it is stuck like that. I learned the hard way a few times and had a vacuum leak at the base plate.
Thank you! And yes, I always go over every single screw to ensure there are no leaks. Thank you for watching! 😊👍🏻
Awesome video clarity. Thank you so much for making this video. The close up procedures are very helpful, and I like the step by step reassembly method which greatly reduces chances of forgetting something. Thank You!!!
Thank you for the kind works and glad to hear you found the video helpful.
Thank you for watching! 😊👍🏻
@@76vette I have the same carburetor and my mechanic tell me the float is sticking on the one That I have could it be that I mess with the idle screw for the fuel that’s got a few porn everywhere is that why thank you greatly appreciate it
@@cadillac9142 The idle screw would not make the float stick. The culprit, most likely, are the needle and seat, so I would start there. And if the float is damaged or defective, have it replaced at the same time. Actually, a carb rebuild may not be a bad idea. Good luck 😊👍🏻
Great video! I've never rebuilt a quadra jet yet, but plenty Carter AVS and Thermoquad carburetor's and Holley 4150's. But now that I'm getting back into Corvette's I may have to tackle one in the future, best thing is i can go back to your videos if i get lost on one along the way! Thanks for sharing!
Thank you so much for watching my Quadrajet videos. And I hope they’re helpful. I recently rebuilt a 702 that’s going on a 68 Vette with a 350, so there will be at least one more Qjet video. And that’s it for a while. lol 😆
Great set of videos on the rebuild. thanks for sharing.
Thank you for watching! 😊👍🏻
@@76vette if you work on the M4ME carb. Can or do you have a video on how to tune or adjust the lean mixture screw and solenoid ?
@@brianfong3954 I wrote a blog article a few years ago that may be helpful, www.76vette.com/2018/12/quadrajet-tuning-adjusting-idle-mixture.html
I subscribe to you now. Another great video with excellent views. That's a cool base with the Chevy flags. That's enough to inspire me to make a few bases for various models. I'm going to have to dig up some respective emblems. Thanks.
Awesome. Thank you for your support 😊👍🏻
Badass. Especially when you showed the mistake you made and how to fix it.
Thank you for watching! 😊👍🏻
hey there, good informative video. I have destroyed my secondary flap spring. do you know what part number for that.

Thank you for watching! 😊👍🏻
I need to replace the vacuum pulloff on the metal bracket of a divorced choke. How do you pry or remove it from the bracket? Thanks
It’s usually held in place by two prongs that are part of the bracket itself, so you want to pry those open to remove it. 😊👍🏻
Any advice for finding decent unmolested units to practice rebuilding on? I’d like to try it myself but don’t wanna go all in on my running carb.
That’s the smart approach!
I usually see Quadrajets at swap meets, and if you can find one that matches yours, even better. Write down the carburetor numbers and bring them with you to ensure you’re buying the right carburetor.
Learning how to decode the numbers is not hard so do some research to be prepared.
Sometimes you can find one on Craigslist or the FB Marketplace.
Prices can be all over the map, but expect to spend anywhere from $50 to $75 for a carb in good condition. Older Quadrajets usually cost more.
And buy one for a Chevy so you’ll be able to install it without much trouble and run it while rebuilding the original unit.
If your car has auto trans, make sure the one you buy is for an automatic. AFAIK, Quadrajets for cars with 4-speed manual transmissions will not have a kick down lever.
Good luck and thank you for watching! 😊👍🏻
@@76vette great info, thank you!
