Any tricks on getting squirter check valves out of a center

Without taking off the center carb off the engine?
Mine are gunked up from this crappy gas.
Want to get out to the local cruise tonight.

Pull the squirter part off and if it is has a square check valve shoot some carb cleaner on top of it and let it sit a little while, do that again and try and use a small diameter wire to move it around to make it loosen so it will squirt
If it has a round check valve take the carb off first and go from there

It's a stock OE 6 barrel carb. No modifications.

A magnet might work.

I've used this method several times, just try to wiggle it around with a stiff wire or tiny screwdriver.
Now be careful about opening the throttle without the nozzle in place, it might shoot out and fall in the carb or engine!
You don't want to make more work for yourself!
