Quadrajet Problem Solving > Diagnose a Quadrajet carburetor problem
1979 Firebird Trans Am aka the turdbird has problems
Ponchonutty:
Little update. So found out not only is the secondary cam non-existent, I've got a plugged POE. When I sent this carb in the first time, I was told it had rust in the bottom of the bowl. I took a mason jar and cranked it over a little and sure enough, rust (pictured). That prompted me to replace EVERYTHING. Tank, sender, all lines including return and vent, and pump. Still had the sticking problem so I sent it back. He sent me pics saying the carb still has junk inside as shown in pic of cut open fuel filter. I don't know how that could have happened since again, ALL OF THE FUEL RELATED ITEMS WERE NEW AND EVEN FLUSHED PRIOR TO INSTALLING THE CARB THE FIRST TIME. Anyways here I am rebuilding this carb for the 3rd time :-[
Ponchonutty:
Second rebuild. No warranty due to contamination according to the rebuilder
Ponchonutty:
Plugged POE
Ponchonutty:
Filter as shown last year allegedly from fuel contamination on an entirely new fuel system.

What I found in the first rebuild which prompted me to replace everything.
