Help a NOOB - A continuing saga

Look in the carb when it’s running. Use a small flashlight. If you see any fuel at all then it’s flooding.

When you do also look for the two screws you need to remove when you pull the top off the carb.
Here’sa Quadrajet manual in this list for you. Just open the one you need.

Another rebuilder is http://quadrajetpower.com/ out of Texas. They rebuilt mine, including re-bushing of the throttle shafts and I was happy with the result.

Lots of great advice in this thread, the biggest thing is to just keep at it. It sounds like several variables are in play and methodically working your way through them is the best approach. I agree with others that solving the flooding issue is priority 1.

If you have the time to dive into it--and to be methodical doing it--do what someone else suggested and remove your carb to the bench and check it out. Lots of good material out there on rebuilding to get you through the assembly, including the very important but often overlooked tip about how the needle hangs on the float.

IMO the Qjet isn't complicated but it is nuanced, patience and understanding of its systems will go a long way.

I definitely see something. Got some pictures, but a video may be more informative. I have to figure out how to get one up, we can link to youTube correct?

Thanks!

That carburetor does not appear to have been rebuilt. At all. It certainly shouldn't have all that soot in the primary bores, in any event. If you get any guff from the shop who claims they rebuilt this, refer to your state's version of the Bureau of Automotive Repair. You got ripped off, imo.

The item in Pic 2 is the Transmission Controlled Spark solenoid. It limits vacuum advance until the engine is warmed up (there is a thermostatic switch in line, which may have been removed), and the transmission is in high gear. It helps with quicker warmups and to lower hydrocarbon emissions.

How long ago was this carb supposedly "rebuilt"?

That pic showing inside the air horn tells me the carb was not dipped as part of the rebuild process...I would never perform a rebuild without dipping the entire carb body and top...

There is a considerable amount of built up crud inside the air horn, the air bleeds are filthy and the general condition is poor.

I can see fuel dampness inside the air port indicating the fuel float level is way too high...obviously not correctly set during rebuild.

Its no wonder you are having issues...

Re guaranteedcarburetors experiences...I have purchased 4 Quadrajets over the past 12 months from them...nothing but good results from these guys...
I use these on engine builds for clients and usually supply a wrecker yard second hand one in exchange...(why dont I build them myself ?...sometimes I do but its usually a time crunch situation...I order online, it turns up and works...)

I would be demanding a refund from this shop of horrors....

Just my two cents worth...

I just picked it up a week ago yesterday. June 27th.

I tried to call them today, but got no answer. Hopefully they are just closed for the holiday still... oh man... I am so disappointed.
