My Dad, a gentleman who is getting on in years and who still enjoys noodling with old cars, has a 1981 el camino with a 305 and 4 barrel electronic quadrajet carb. He has a couple questions, as he is stuck…yesterday he watched Eric’s video here:
He does not use computers and would have loved to call Eric to ask his question, but I didnt want to break eric’s rule about contacting him about specific automotive questions, so here I am!
If anyone is so kind to help, here they are:
1. Does the small barrel coming from the solenoid, going to the float, that sits down in the carburetor — does it have a spring under it?
2. In the video, the small rod (as big as the inner ink tube of a ball point pen), which you were screwing out above the solenoid — does that little rod have a spring under it?
3. Are there any other springs in that area?
My dad would absolutely love a phone call with a knowledgeable person person about these carbs…but if anyone has any idea at all and you just reply here, thats a huge help as well!

many thanks! he has this question…
regarding this page, http://www.hotrod.com/articles/ccrp-0908-qjet-carburetor-rebuild/
he wants to know if you guys know how to buy JUST this spring?
Secondly, anyone know how tight this needs to be?
Thanks!
I’m going to suggest calling these people to see if you can get just the spring.
I’m also going to suggest a service/rebuild manual for the carb. It would be a
valuable piece.I had an EM4E and man, what a piece of trash! I have a 1981 El Camino as well and the best thing I did was find a cheap, older quadrajet and rebuild it for like $30. The electronic ones are such a pain! I don’t think that the solenoid for the metering rods has a spring. It wouldn’t survive long going up and down 10 times a second full bore for too long. It’s just an electromagnet. So far as I recall the screws near the primary metering rods are the rich and lean stops. If any of the sites linked above make me wrong, that’s fine. I tried to forget about that god forsaken carburator a long, long time ago. Thing is, they are fine carbs with the stock ECU. But to modify the drivetrain at all, you pretty much have to throw all the electronic CCC (Computer Command Control) stuff out the window.
