Quadrajet question

I could use some advice from the carb guru's.
I have a recently rebuilt and tuned quadrajet. It has a slight stumble off idle. I blamed it on timing and possibly low idle.
I worked this weekend to address those issues and it still had the off idle stumble. I looked down the carb at the squirters and it only squirted on the drivers side. Any ideas what is up?

You can try removing the 5/8 fuel inlet nut and blowing compreesd air in the neck and see if it clears the passage out

Have a look at the accelerator pump cup I bet it is ripped.Did you replace the accelerator pump? If it is ,it doesn't push through enough fuel to the squirters . Unfortunately you'd have to the carb apart again.

Wear safety glasses. Those carb channels do u turns and your air blaster might put fuel in your eyes.

Thanks for the suggestions guys. I will try blowing through the inlet this weekend and if that doesn't work pull the top off and check the pump and passages.

Inlet only goes past needle and seat into the bowl.

Not all that connected to the accel. circuit.
Easy enough to try though.
