Dragging = sounds like the battery is run down but it's not, turning over very slowly (only with operating temp motor).

Get it warmed up to OT before adjusting. Operating Temperature for those who drive Fords.

Sounds like sluggish performance

Vacuum ports are all accounted for or plugged, with the exception of the small port that goes to the breather nozzle thing.

My choke was floppy and the flap stayed open until I adjusted the choke element. Now it starts closed and has a spring to it when pushed open. The truck hasn’t ran long enough to warm up to see if it opens by itself. The vacuum thingy near choke operates when I manually checked it with thumb over the end of the port.

I had to back the main screws up front back several half turns to get it this good even. So I’m pretty sure they wereentnletting air/fuel in. They still may need to be unscrewed some?  Maybe 3 turns out so far.

Idle speed screw? Not touched it. Fast idle cam screw? Haven’t touched it.   The screw under the choke element and the screw under the throttle linkage is what you mean??  I haven’t touched them. But they may have been wrong to begin with. (Field find sitting since 96)

It runs if I give gas. I let off and it dies within 3-5 seconds.

Assuming you have no vacuum leaks, and everything is hooked up correctly, is the choke working? Are you adjusting the fast idle speed screw? Off of the fast idle cam, are you adjusting the idle speed screw? Does it run if you give it throttle?

What do you mean dragging?

Fuel Systems and Drivability / Reinstalling Quadrajet- getting it to run right

Hello all,

I have just finished rebuilding my first carburetor!

Rochester Quadrajet.

I will say, I’ve put this off because it’s looked scary, but just like electrical work in the past, I got on here and snooped around enough, watched hours of YouTube videos and read manuals both hard copies and pdfs and cinched my belt up and did it.

I will say that the rebuild went smoothly and wasn’t nearly as daunting as I thought it would be. I will admit I didn’t get too carried away and just basically cleaned all the old gas and gunk out. Lots of elbow grease and chemicals and I feel like a very clean finished product was presented. I did not take out restrictors or cups or any super tiny pieces and just made sure they were clean and clear of obstructions.

I reinstalled the thing the other day and got the truck (1986 C20- 350/350) to start but it died quickly.

A few tubes of main screws up front and realizing my choke wasn’t set correctly I managed to keep the truck running for a little bit. And it was pretty smoothe compared to before the cleaning.

Here’s my question:

How do I dial it in where I can just turn the truck on? Lol.

Big question I guess.

I’m not sure I have any setting correct and I’m just out there blindly trying. I don’t really have anyone to help that would know about carburetors (or cars at all really) that could come stop by.

I’m currently looking at the Haynes charts on my specific carb but don’t know what it means. It’s like Greek.


I snooped on here and saw lots of quafrajet questions, but they seems specific to already running and just maximizing performance. Also,  I may have missed something obvious in the read only sections. So sorry if I did.

Thanks for any help yall can send my way!

I had this a few years back. Replaced starter and still had dragging. Replaced cables and solved problem. Cables were probably original, no way of knowing. Be sure battery is good also. Recommend getting AC Delco starter if you can. I also got a starter heat shield wrap just in case it may need it.

The starter turns over good when engine is cold BUT after driving 20 - 30 minutes it drags bad and won't start until it cools down.

Do I just need a new starter?
If so, where would y'all get one?  Just local auto parts house?

I've had quotes of 24K, I think theirs was just south of 10.

I painted my first resto at 22, '67 Olds Toro, have been used to doing my own work since before then.

Downsizing has me at a disadvantage, no place to do this kind of work anymore. 

I enjoy your posts of the projects, especially of your children included. Seems like you do most of your own work too.

I taught my daughters to change their own oil, brakes, and other maintenance items.
