Default Quadrajet carb leaking


Hope anyone can help me with this. My quadrajet carb is ultrasonic cleaned and put a revision kit into it. After the first test drive I found out that is leaking quite a bit at the plug of the accelerator pump well. This plug seems to be open. Is this correct or should this be closed?

thanks for the he

lp

The plug is missing. That hole should be plugged.

Thanks! Is this a separate plug or can I just fill it with JB-weld?

It's a pressed-in plug. Not uncommon the the UT cleaning systems to knock the plugs loose and cause leaks in the other plugs. Filling the hole with JB is a bad idea - it will not prevent it from leaking over time. The hole needs to be drilled and tapped about 1/8" deep. Then, a 1/8" long socket head flat tipped set screw needs to be installed - this set screw should have the threads coated with JB. Install it until it bottoms hard against the bottom of the short-tapped threads.

Thanks for the advice I followed it 😉
Drilled a hole and tapped it. Put a screw in it with a flat tipped head and put some jb-weld on the threat.
